In today’s increasingly multilingual world, the need to translate PDF files is more common than ever. Whether it’s a school transcript, a legal document, or a user manual, users often face the challenge of translating PDFs without losing formatting or accuracy. This guide walks you through the most effective online tools and real-world use cases—plus a tip for translating PDFs on the go with AI Phone.
Why Do People Need to Translate PDFs?
PDFs are widely used for sharing official and structured documents, from application forms to medical records. Common scenarios include:
- Immigrants translating government-issued forms (e.g., immigration, healthcare, DMV)
- International students converting school certificates into their host country’s language
- Freelancers or business professionals translating project briefs or NDAs
- Travelers reading travel guides or medical information in foreign languages
However, PDFs are not always easy to translate. Many are scanned, non-editable, or contain complex formatting that typical translation tools can’t handle well.

How to Translate a PDF Using Google Translate
For basic translation needs, Google Translate works well. Here’s a simple step-by-step:
- Go to translate.google.com
- Click on “Documents” → Upload your PDF (max 10MB)
- Select the source and target languages
- Click “Translate”
- View and copy the output (Note: layout will likely be simplified)
What If the PDF Is Scanned or Non-Editable?
In many cases, especially with official forms or printed materials, your PDF is an image (not actual text). You’ll need OCR (Optical Character Recognition) to make it translatable.
Free OCR Tools:
- iLovePDF OCR
- SmallPDF OCR
Once you’ve extracted the text, use translation tools like DeepL or DocTranslator to proceed.
Tips to Preserve Formatting
Many translation tools strip out design elements. Here’s how to maintain the original layout:
- Convert the PDF to Word using Adobe Acrobat or iLovePDF
- Translate the Word file using DeepL or DocTranslator
- Save back as PDF once done
This method gives you more control over formatting and allows you to manually adjust translations if needed.
