Why Collaborate on PDFs?

Imagine this: You’re working on a project, and a teammate sends you a PDF for review. You add comments and send it back. Then another teammate makes their edits and sends yet another version. Before you know it, you’re drowning in an email chain filled with multiple versions of the same document, unsure which one is the latest. Sound familiar?

Collaboration on PDFs has traditionally been a hassle, but in today’s fast-paced digital world, real-time teamwork is essential. Whether you’re a professional working on contracts, a student reviewing research papers, or a designer finalizing a presentation, being able to edit, comment, and share PDFs with others seamlessly can save time and eliminate confusion.

Thankfully, modern tools make PDF collaboration easier than ever. From cloud-based solutions like Adobe Acrobat Online and Google Drive to dedicated PDF editors like PDF-XChange and Foxit, there are multiple ways to work together without constantly downloading and emailing files.

In this article, we’ll explore the best methods and tools for editing PDFs with others, covering everything from real-time commenting to full document editing. Whether you need simple markup tools or advanced co-editing features, you’ll find the perfect solution to streamline your workflow.

Can You Really Edit PDFs Together?

PDFs are designed to preserve document formatting, making them ideal for sharing across different devices and operating systems. However, this very feature also makes them less flexible when it comes to real-time editing. Unlike Word or Google Docs, PDFs weren’t originally built for live collaboration, which presents some challenges.

The Challenges of Editing PDFs

Unlike cloud-based word processors, PDFs are static files, meaning real-time edits aren’t as straightforward. Here are some common challenges teams face when collaborating on PDFs:

• Lack of Live Editing: Unlike Google Docs, PDFs don’t support simultaneous editing by multiple users. This leads to version chaos, where different people work on separate copies, making it hard to track changes.
• Merging Multiple Versions: If several team members make edits on different copies, combining them manually can be frustrating and time-consuming.
• Limited Track Changes Feature: Many PDF editors allow annotations but don’t have a built-in “track changes” function like Microsoft Word, making it harder to see who made what changes.
• Editing Restrictions: Some PDFs are locked or require special software to modify, which can slow down collaboration, especially for teams working remotely.

Despite these challenges, PDFs remain one of the most widely used formats for sharing and collaborating on documents.

Why PDFs Are Still a Go-To for Collaboration

Even though editing PDFs together isn’t as seamless as in cloud-based documents, they still offer several advantages that make them a preferred format for collaboration:

• Security and Document Integrity: PDFs maintain formatting across all devices, preventing accidental layout shifts that often happen in Word documents. They also offer encryption, password protection, and restricted editing, making them ideal for sensitive business documents.
• Universal Compatibility: Unlike proprietary file types, PDFs can be opened on almost any device without needing specialized software, ensuring that collaborators can access the file regardless of their operating system.
• Annotation and Commenting Tools: Modern PDF editors like Adobe Acrobat, Foxit PDF, and Nitro PDF offer markup tools that allow multiple users to highlight, comment, and annotate PDFs without altering the original content.
• Cloud-Based Editing Solutions: Platforms like Google Drive, Adobe Acrobat Online, and Smallpdf now enable real-time PDF editing and annotation, reducing the need for endless email chains and multiple file versions.

While PDFs weren’t originally built for collaborative work, evolving technology has made it much easier to edit and share them efficiently. The key is choosing the right tools that align with your workflow, whether that’s simple commenting features or full-fledged editing capabilities.

Best Ways to Collaboratively Edit PDFs

1: Using Adobe Acrobat for Team Editing

Adobe Acrobat remains one of the most powerful tools for collaborating on PDFs, offering a suite of features that allow teams to review, annotate, and edit documents efficiently. Whether you need to add comments, track changes, or enable real-time collaboration, Adobe Acrobat provides a structured workflow that ensures all edits are organized and accessible.

How to Add Comments and Annotations

One of the easiest ways to collaborate on a PDF in Adobe Acrobat is through its commenting and annotation tools. These tools allow multiple users to provide feedback without altering the original document.

Step-by-Step Guide to Adding Comments:

1. Open the PDF in Adobe Acrobat (Pro or Standard).

2. Click on the Comment tool from the right-hand toolbar or go to Tools > Comment.

3. Choose from various annotation options:

• Sticky Notes: Click anywhere on the PDF to drop a note with feedback.
• Highlight & Underline: Select text and choose the highlight or underline tool to mark important sections.
• Strikethrough: Cross out text that should be removed.
• Drawing Tools: Use shapes, lines, or freehand drawings to provide additional visual feedback.

4. Each comment is tagged with the reviewer’s name and a timestamp for easy tracking.

5. Once all comments are added, the file can be saved and shared for further review.

This method is ideal for team reviews where feedback needs to be gathered without modifying the original document.

Enabling Real-Time Document Sharing in Adobe Acrobat

Adobe Acrobat also allows real-time collaboration through Adobe Document Cloud, ensuring that multiple users can review and comment on the same document simultaneously.

How to Share a PDF for Team Editing in Real-Time:

1. Open your PDF in Adobe Acrobat DC.

2. Click on Share in the upper-right corner.

3. Enter the email addresses of the team members you want to collaborate with.

4. Choose Allow Commenting (if you only want feedback) or Allow Editing (if full document changes are needed).

5. Click Send, and the file is uploaded to Adobe Document Cloud.

6. Team members receive an email link, allowing them to open and edit the document in their browser without needing to download Acrobat.

By using cloud-based collaboration, you eliminate the hassle of sending multiple versions via email and ensure that everyone is working on the most updated file.

Tracking Changes and Resolving Feedback Efficiently

One of the major advantages of Adobe Acrobat is its ability to track changes and keep feedback organized. Here’s how to make the most of these features:

Reviewing and Resolving Comments:

1. Open the PDF and navigate to the Comments panel.

2. Click on any comment to see who made it and when.

3. Reply to a comment directly by clicking on it and adding a response.

4. Once feedback has been addressed, click Resolve to mark it as completed.

Using the Compare Files Feature:

If multiple versions of a document exist, Adobe Acrobat’s Compare Files feature helps identify changes:

1. Open Acrobat and go to Tools > Compare Files.

2. Select the two versions of the PDF you want to compare.

3. Acrobat will highlight insertions, deletions, and modifications between the files.

4. Click through each change to see details and decide which edits to keep.

Exporting Comments for External Review:

If you need to consolidate feedback from multiple reviewers, Acrobat allows you to export all comments into a summary file:

1. Go to Comment > Summarize Comments.

2. Choose Create a PDF Summary to generate a separate document listing all annotations.

3. This makes it easier to review feedback at a glance and make final revisions.

Why Use Adobe Acrobat for Team Editing?

✔ Best for professional teams handling contracts, reports, and design approvals.

✔ Organized commenting system that keeps feedback structured.

✔ Real-time collaboration with cloud-based sharing and editing.

✔ Secure document handling with access control and encryption.

While Adobe Acrobat is a paid tool, its robust features make it the best choice for teams that need a structured, efficient, and secure way to collaborate on PDFs. Whether you’re working on business documents, legal files, or creative projects, Acrobat streamlines the editing process and ensures that no feedback gets lost in endless email chains.

2: Editing PDFs in Google Drive

Google Drive offers a convenient way to store, share, and collaborate on PDFs, but editing them directly can be tricky. Since PDFs are not natively editable in Google Drive, users often need to convert them into an editable format or use Google’s built-in annotation tools. While this method is useful for teams who work with Google Docs frequently, it has its limitations, especially when dealing with complex PDF layouts or heavily formatted documents.

Converting PDFs to Google Docs for Easier Edits

One of the simplest ways to edit a PDF in Google Drive is by converting it into a Google Docs file. This allows multiple users to make changes in real-time, just like they would with any other Google document.

How to Convert a PDF to Google Docs:

1. Upload the PDF to Google Drive.

2. Right-click the file and select Open with > Google Docs.

3. Google Docs will convert the PDF into an editable text document.

4. Once converted, users can edit the text, add comments, and make formatting adjustments.

5. After making changes, the document can be exported back to PDF format by clicking File > Download > PDF Document (.pdf).

✔ Best for: PDFs with mostly text-based content, such as contracts, reports, and meeting notes.

❌ Limitations: If the original PDF contains complex formatting, images, or tables, the conversion may distort the layout.

Sharing PDFs with Google Drive and Using Suggestions/Comments

If editing the text of a PDF isn’t necessary, users can still collaborate on PDFs using Google Drive’s built-in commenting tools. This is useful for providing feedback and making suggestions without altering the original file.

How to Share and Comment on PDFs in Google Drive:

1. Upload the PDF to Google Drive.

2. Right-click the file and select Open with > Google Drive Viewer.

3. Click the comment icon (a speech bubble with a plus sign) in the top right corner.

4. Highlight text or click anywhere in the document to leave a comment.

5. Team members can reply to comments, resolve feedback, and track discussions in real-time.

✔ Best for: Teams reviewing PDFs that don’t need direct text edits, such as proposals, legal documents, and design proofs.

❌ Limitations: Google Drive doesn’t allow editing within the original PDF, only commenting and suggesting changes.

When This Method Works Best (and When It Doesn’t)

✅ Best Situations for Google Drive PDF Editing:

• When you need real-time collaboration with team members who primarily use Google Docs.
• If the PDF contains mostly text, making it easy to convert into an editable Google Doc.
• For leaving feedback and comments without changing the original document.

❌ When Google Drive Isn’t Ideal:

• If the PDF contains complex formatting, tables, or graphics, since conversion may distort the layout.
• When working with confidential documents, as converting PDFs to Google Docs may strip security settings.
• If you need advanced editing features like adding watermarks, adjusting layouts, or merging pages—Google Drive lacks these capabilities.

Google Drive provides an easy way to collaborate on PDFs, but it works best for reviewing and commenting rather than full-scale editing. If your team primarily uses Google Workspace and you only need to make text-based changes, converting to Google Docs can be a simple solution. However, for heavily formatted documents or secure files, a dedicated PDF editor like Adobe Acrobat or a third-party tool like PDF-XChange may be a better choice.

3: Online PDF Collaboration Tools

Collaborating on PDFs online has become easier thanks to a variety of web-based tools that allow users to edit, annotate, and share PDFs without installing software. Platforms like Smallpdf, PDFescape, Sejda, and PDF-XChange Editor provide powerful features for teams to work on documents in real time. These tools eliminate the need for endless email threads with multiple versions, offering a streamlined way to review and finalize PDFs. However, while online tools are convenient, they come with limitations compared to full desktop PDF editors.

Overview of Popular Online PDF Collaboration Tools

Here’s a look at some of the best online platforms for editing and sharing PDFs:

1. Smallpdf – A user-friendly online PDF editor with features for adding text, annotations, and e-signatures. It supports cloud-based storage and easy file sharing.

Pros and Cons of Online PDF Tools vs. Desktop Solutions

While online PDF editors provide accessibility and ease of use, they don’t always match the power of desktop applications like Adobe Acrobat or Foxit PhantomPDF. Here’s a breakdown of their strengths and weaknesses:

✅ Pros of Online PDF Tools:

✔ Accessibility: No need to install software—works directly in a web browser.

✔ Easy Sharing: Generate shareable links for team collaboration.

✔ Cloud Integration: Many tools connect with Google Drive, Dropbox, and OneDrive.

✔ Cost-Effective: Most platforms offer free basic editing and commenting features.

❌ Cons of Online PDF Tools:

❌ File Size Limits: Many free versions restrict file uploads to a certain size (e.g., 50MB).

❌ Limited Advanced Features: Some features, like advanced editing, encryption, or OCR, are only available in premium versions.

❌ Internet Dependency: Requires a stable internet connection for access and collaboration.

❌ Security Risks: Uploading sensitive documents to online tools may pose privacy concerns.

Online PDF collaboration tools are excellent for quick edits, real-time feedback, and easy sharing, making them ideal for teams working remotely. However, they may not be the best option for confidential or highly formatted documents that require more advanced editing and security.

For casual users, Smallpdf or Sejda are great choices for simple modifications and comments. For teams needing more control over document formatting and security, a desktop solution like Adobe Acrobat or PDF-XChange Editor is the better long-term investment.

Choosing the right tool depends on your team’s workflow, security needs, and collaboration style. If you need frequent PDF editing with team input, combining cloud-based tools with a desktop editor can provide the best of both worlds.

4: Microsoft Teams, OneDrive & Other Collaboration Tools

Microsoft’s ecosystem, particularly OneDrive and Teams, offers a robust, integrated environment for PDF review and collaboration. OneDrive serves as a secure, cloud-based storage solution where you can easily upload and manage PDF files. Once uploaded, you can share these documents with your team, control access permissions, and maintain a detailed version history to ensure that every change is tracked. This centralization simplifies document management, reduces the risk of working on outdated files, and streamlines the review process.

In Microsoft Teams, PDF collaboration becomes even more dynamic. You can attach PDFs stored on OneDrive directly into Teams channels or chats, allowing team members to access the files without leaving the application. Teams supports integrated commenting and discussion threads, so users can provide immediate feedback, tag colleagues, and discuss specific sections of the document in real time. During meetings, you can share your screen to review PDFs together, annotate live, and resolve questions on the spot, creating a seamless interactive review experience.

Integration with Office apps further enhances this workflow. Although native PDF editing isn’t a core feature of Word or PowerPoint, these applications work hand-in-hand with OneDrive for tasks like converting PDFs to editable formats when necessary. For example, if textual revisions are required, you can convert the PDF to a Word document, make the edits, and then save it back as a PDF—all within the Microsoft ecosystem. This integration ensures that teams can leverage familiar Office tools while maintaining consistency and security across all documents.

When comparing different collaboration workflows, Microsoft’s approach stands out for its centralized and cohesive design. Unlike standalone online PDF editors such as Smallpdf or Sejda which typically function as isolated tools with separate interfaces, Teams and OneDrive provide a unified workspace. This integration not only reduces the need to switch between multiple applications but also minimizes compatibility issues and enhances data security. Additionally, the ability to set granular permissions and track every version makes it easier to manage revisions and ensure accountability throughout the collaboration process.

Keeping Track of Changes in a Shared PDF

When multiple people collaborate on a PDF, tracking changes effectively is crucial to maintaining clarity and avoiding conflicting edits. Unlike Google Docs or Word, PDFs don’t have built-in real-time version tracking, which means teams must use annotations, version control, and structured naming conventions to ensure a smooth workflow. Here’s how to keep everything organized.

Best Practices for Tracking Edits and Avoiding Conflicts

1. Use Commenting and Annotations Instead of Direct Edits

Instead of making direct changes to the content, use commenting tools available in PDF editors like Adobe Acrobat, PDF-XChange Editor, or online platforms like Smallpdf and Sejda. Highlight sections, add sticky notes, and use strikethroughs or underlines to mark changes without altering the original document.

2. Assign Different Colors or Initials for Reviewers

Some tools allow users to choose different colors for their comments or add their initials. This makes it easy to differentiate feedback from multiple team members. Adobe Acrobat, for example, automatically tags comments with usernames, making it clear who suggested what.

3. Avoid Simultaneous Editing Without a Plan

Unlike live collaboration tools like Google Docs, PDFs do not update in real time. If two people edit different versions at once, changes may be lost or overwritten when merging files. To prevent this, set a workflow where one person at a time makes edits, or use a shared cloud platform (OneDrive, Google Drive) with clear access control.

Using Version Control and Timestamps for Clarity

1. Save and Label Versions Clearly

Instead of overwriting the same file, save different versions using version numbers or timestamps (e.g., “Project_Proposal_v2.pdf” or “Report_2025-02-25.pdf”). This helps track progress and revert to previous versions if needed.

2. Enable Version History in Cloud Storage

Platforms like OneDrive, Dropbox, and Google Drive automatically store previous versions of a file. This allows users to restore earlier edits if necessary.

3. Use File Comparison Tools

Some PDF editors (like Adobe Acrobat Pro and PDF-XChange Editor) offer document comparison tools that highlight differences between two versions of the same PDF.This is useful when multiple people are editing separately and need to merge changes later.

Naming Conventions and Saving Finalized PDFs

1. Use Consistent Naming Conventions

Standardizing file names helps teams quickly identify the latest version and avoid confusion.

A simple and effective structure includes:

• [Project/Document Name][Version/Date][Editor Initials].pdf
• Example: Marketing_Plan_v3_JD.pdf (for John Doe’s version)

Example: Annual_Report_2025-02-25_Final.pdf (final approved version)

2. Mark Finalized PDFs Clearly

• Once the document is finalized, add “FINAL” to the file name (e.g., “Contract_Approved_FINAL.pdf”).
• Lock the file to prevent further edits (Adobe Acrobat allows password-protecting or flattening PDFs).

3. Share the Final PDF in a Central Location

• Store the final version in a designated folder within your team’s cloud storage (OneDrive, Teams, Dropbox).
• Send out a final confirmation message to notify all collaborators that no further changes should be made.-

Keeping track of changes in a shared PDF requires a structured approach. Using annotations, version control, and proper naming conventions ensures that teams avoid confusion and maintain a clear record of edits. By leveraging tools like Adobe Acrobat’s comparison feature, cloud-based version history, and well-organized file naming practices, teams can streamline collaboration and prevent unnecessary back-and-forth revisions.

Conclusion

Collaborating on PDFs doesn’t have to be a chaotic process filled with endless email attachments and conflicting edits. With the right tools and best practices, teams can seamlessly review, edit, and finalize PDFs without losing track of changes.

Key takeaways for smooth collaboration:

• Use cloud-based storage like OneDrive or Google Drive to ensure access and version control.
• Leverage tools like Adobe Acrobat, Sejda, or Smallpdf for commenting and minor edits.
