Why Do You Need to Translate a PDF File?
PDF files are widely used for business, education, legal documents, and official records. However, when a document is in a language you don’t understand, translating it becomes essential. Here are some key reasons why you might need to translate a PDF:
1. Business & International Communication
Companies operate globally, meaning contracts, reports, and presentations often need translation. Whether it’s a business proposal, marketing material, or employee handbook, translating PDFs ensures seamless communication with international clients, partners, and employees.
✅ Example: A company expanding to a new market may need to translate legal agreements for local compliance.
2. Academic & Research Purposes
Students, researchers, and educators frequently encounter PDFs in different languages. Translating these documents helps access global research papers, textbooks, and academic articles, making knowledge more accessible.
✅ Example: A student studying global history might need to translate foreign historical documents for research.
3. Legal & Government Documents
Legal contracts, court rulings, and immigration papers are often in a specific language. For official processes, accurate translation is crucial to ensure clarity and compliance with local laws.
✅ Example: Someone applying for a visa might need their birth certificate and legal documents translated.
4. Personal Use & Everyday Needs
People often receive PDFs in different languages, whether it’s a manual, recipe, or personal correspondence. Translation makes it easier to understand and use the information.
✅ Example: If you buy a product from another country, translating the instruction manual helps in proper usage.
Translating PDFs bridges language barriers in business, education, law, and personal life. With free translation tools available, accessing information in any language has never been easier!

Let’s get started!
Best Free Tools to Translate PDF Files
Translating a PDF file doesn’t have to be a tedious process, especially with the many free tools available online and offline. Whether you need to translate a business contract, an academic paper, or a personal document, there are options that cater to speed, accuracy, and formatting preservation. Some tools focus on delivering quick and simple translations, while others provide high-quality language accuracy or ensure that the document’s layout remains intact. Choosing the right tool depends on your specific needs and whether you prefer an online or offline method.
One of the most widely used tools is Google Translate, which allows users to upload an entire PDF and translate it into over 100 languages for free. It’s a fast and easy solution, making it perfect for general translations. However, Google Translate often removes original formatting, which can be inconvenient if your document contains tables, images, or special layouts. If formatting is a concern, DocTranslator is a great alternative. It uses Google Translate’s translation engine but preserves the original structure of the document, ensuring that everything stays in place. Plus, since it works entirely online, there’s no need to install any software.
For those who prefer an offline translation method, Microsoft Word offers a built-in translation feature. By opening a PDF as an editable Word document, users can translate it using Microsoft Translator before saving it back as a PDF. This method is useful for those who frequently work with Word and need a quick, offline solution. However, because Word converts PDFs into an editable format, it may slightly alter complex layouts or formatting.
If translation accuracy is your main concern, DeepL is one of the best free tools available. While it supports fewer languages than Google Translate, it provides more precise and contextually accurate translations, making it ideal for business, legal, and academic documents. DeepL captures language nuances better than many other tools, which is crucial for professional settings. Now that we’ve covered the best free tools, let’s explore how to use them step by step!
1. How to Translate a PDF Using Google Translate (Step-by-Step)
Google Translate is one of the fastest and most accessible tools for translating PDF files. Whether you need a quick translation for a business document, academic paper, or personal file, Google Translate makes it easy to get the job done in just a few steps. The best part? It’s completely free and supports over 100 languages, making it one of the most versatile translation tools available. However, while it’s excellent for general translations, it does have one major drawback—it doesn’t preserve the original formatting of the PDF. If your document contains tables, images, or special layouts, the translated version will only display plain text.
Step-by-Step Guide
1. Go to Google Translate – Open your web browser and visit translate.google.com. Google Translate is an online tool, so there’s no need to download any software.
2. Click on the “Documents” tab – Instead of pasting text, select the “Documents” option, which allows you to upload an entire file instead of translating manually.
3. Upload Your PDF File – Click the “Browse your computer” button and select the PDF you want to translate. Keep in mind that the document must be under 10MB, as Google has file size limitations.
4. Select the Original and Target Language – Choose the language of the original document and the language you want it translated into. If you’re unsure about the source language, Google can automatically detect it.
5. Click “Translate” – Once everything is set, click the “Translate” button. Google will process the document and generate a translated version.
6. Download or View the Translated Text – After the translation is complete, Google will display the translated text in your browser. Unfortunately, it won’t retain the original formatting, so you may need to copy the translated text into a document and manually adjust it.
Pros & Cons of Using Google Translate for PDFs
✅ Fast & Free – Google Translate processes PDFs within seconds, making it a great option for quick translations.
✅ Supports 100+ Languages – Whether you need a translation in French, Chinese, Arabic, or Spanish, Google Translate has you covered.
❌ Does Not Keep Original Formatting – Google only extracts and translates the text, meaning that tables, graphs, and images will be lost in the translated version.
Alternative for Preserving Formatting
If you need to keep the original layout of your PDF, Google Translate might not be the best option. Instead, consider using DocTranslator, which uses the Google Translate engine but retains the original structure and design of your document. This makes it a better choice for business reports, presentations, and official documents where formatting is important. In the next section, we’ll explore how to translate a PDF without losing formatting!
2. Translate PDFs While Keeping Formatting (DocTranslator)

This is where DocTranslator comes in—it allows you to translate an entire PDF while keeping its layout intact. Whether you’re working with business reports, academic papers, contracts, or brochures, this tool ensures that the translated document looks just like the original.

Looking for an Offline Solution? Try Microsoft Word!
If you need to translate a PDF without an internet connection, Microsoft Word offers a built-in translation tool that works offline. This is useful for sensitive documents that you don’t want to upload to an online server. In the next section, we’ll explore how to use Microsoft Word to translate PDFs directly on your computer—no internet required!
3. Translate PDF Files Using Microsoft Word (Offline)
If you prefer an offline method for translating PDFs, Microsoft Word is a great option. Unlike online tools that require you to upload your document to a server, Word allows you to translate a PDF directly on your computer, making it a more private and secure choice. This is especially useful when dealing with confidential business documents, contracts, or sensitive personal information.
While Microsoft Word’s built-in translation tool may slightly alter formatting, it provides the benefit of allowing you to edit the translated text immediately. Plus, once Word is installed on your device, no internet connection is required to use the translation feature.

While mobile translations may not always maintain formatting, they are perfect for quick reading and understanding. Below are the best free mobile apps for translating PDFs on iPhone and Android devices.
For iPhone & iPad: Using Google Translate App
If you’re an iOS user, Google Translate provides a fast and simple way to translate PDF content. While it doesn’t directly translate entire PDF files, you can use the camera function to scan and translate text instantly.

This method is ideal for physical documents or screenshots of PDFs, but it may not work well for long or complex files.
For Android: Using Google Translate App
Android users have the option to translate entire PDF files directly through Google Translate.
1. Open the Google Translate App – Download the app from the Google Play Store if you haven’t already.

Common Translation Issues & How to Fix Them
While translating PDFs is now easier than ever, some common issues can affect accuracy, formatting, and usability. Here’s how to tackle them effectively.
Issue 1: Formatting Gets Messed Up
One of the biggest problems when translating PDFs is that the original formatting, images, and layout can get completely disrupted. This happens because some translation tools focus only on text and ignore design elements like fonts, tables, and spacing.
✅ Fix: If maintaining formatting is essential, use DocTranslator or Microsoft Word. DocTranslator preserves layouts while translating by converting the PDF into an editable document first. Microsoft Word also allows manual adjustments after translation, ensuring the final version looks clean and professional.
Issue 2: Poor Translation Quality
Not all translation tools provide accurate or context-aware translations. Google Translate, while convenient, sometimes struggles with complex sentences, technical terms, or idiomatic expressions, leading to awkward or unclear translations.
✅ Fix: If accuracy is a priority, use DeepL instead. DeepL is known for its superior language processing, making it ideal for business, academic, and legal documents. It provides more natural and professional translations, ensuring that the meaning stays intact.
Issue 3: File Too Large for Free Tools
Many free translation tools have file size limits, preventing you from uploading large PDF documents all at once. If your file exceeds the limit, you might get an error message or be forced to upgrade to a paid version.
✅ Fix: A simple solution is to split the PDF into smaller sections using a free tool like Smallpdf or iLovePDF. Once the document is split, you can translate each section separately and merge them back together after translation.
