How it works

The tool extracts the text from your PDF in your browser, then sends that text to an AI model to translate.

  • Upload: You upload your PDF and its text is extracted locally, in your browser. The original file itself isn't sent anywhere.
  • Select language: Choose the language you want to translate to, from a list of 30+ supported languages.
  • Translate: The extracted text is sent to PDFly's server, which forwards it to Google Gemini to translate.
  • Review: You get the translated text back on the page, where you can read or copy it.

The process is significantly faster than manual translation, but it's worth noting that speed comes with some trade-offs. The translation quality is generally strong for common languages, but it's not perfect. For most business and personal use cases, it's more than sufficient. For legal contracts or medical documents, you'd still want a human review.

Languages supported

PDF Translator supports 31 languages, covering the needs of most users.

  • Popular languages: English, Spanish, French, German, Chinese (Simplified and Traditional), Japanese, Portuguese, Russian, Italian.
  • Also supported: Arabic, Hindi, Urdu, Bengali, Korean, Turkish, Vietnamese, Thai, Indonesian, Dutch, Polish, Ukrainian, Greek, Hebrew, Swedish, Norwegian, Danish, Finnish, Czech, Romanian, Hungarian.
  • Total: 31 languages are available in the dropdown. Languages outside this list aren't currently offered as a target.

It's worth noting that translation quality varies by language. Common languages like Spanish, French, and German tend to translate more reliably, since the underlying model has seen far more training data for them. Less common languages may have somewhat lower accuracy.

What the output actually is

This is the part worth being clear-eyed about: the tool translates the text content of your PDF, not the PDF itself. What you get back is plain translated text — not a new PDF with the original layout, fonts, images, or table structure rebuilt around it.

  • What's translated: The readable text content of the document, in the order it was extracted.
  • What's not reproduced: Fonts, page layout, image placement, table structure, and hyperlinks aren't carried over into the output — those exist in the original PDF, not in the plain-text result.
  • Best fit: Understanding a document's content in another language, or pulling a translated version of the text to paste elsewhere — not producing a publish-ready translated PDF.

If you need a document that looks like the original but with translated text in place — same fonts, same layout, same tables — you'd need to rebuild that manually or with dedicated desktop publishing software after translating the text here.

When to use a PDF translator (and when not to)

This tool is most useful when you need to understand a document in another language without waiting for a human translator. Business proposals, internal communications, personal documents, and academic papers are all good candidates.

However, there are clear limitations. The tool should not be used for legally binding translations unless you have a human review. It shouldn't be used for documents where precision matters — medical records, patent applications, or anything where a single word makes a difference. And it works best with well-structured, clearly written text. Handwritten notes or documents with unusual formatting will produce lower quality results.

It's also worth thinking about your audience. If you're translating a document for yourself, the tool is perfect. If you're translating a document for a client or a colleague who doesn't speak the source language, the tool is also perfect — but you should still review it before sending. If you're translating for a public-facing audience where the translation represents your organization, the standard is higher.

A note on privacy

The file itself is opened and its text extracted locally, in your browser — the original PDF is never uploaded. To generate the translation, that extracted text is sent to PDFly's server, which forwards it to Google Gemini, our AI provider. PDFly processes the extracted text for the request; see the Privacy page for the current data-handling policy. If you're translating something highly sensitive that shouldn't leave your device at all, that's worth weighing before using this tool specifically.

If you're translating something that shouldn't leave your device in any form, this tool isn't the right fit — the extracted text, even though the original file stays local, still goes to an external AI provider to be translated.

Limitations

  • The extracted document text is capped at 40,000 characters (roughly 10,000 tokens). Longer documents are automatically truncated to the 40,000-character limit before translation.
  • The tool translates the text content — it doesn't rebuild the original PDF's layout, fonts, or images in the output.

Frequently Asked Questions

How accurate is the translation?

The AI provides generally strong translations for common languages, but it may not be perfect for technical or highly specialized content. For critical documents, consider a human review.

Can I translate a scanned PDF?

Only if it has selectable text. This tool doesn't include OCR itself — run a scanned PDF through OCR PDF first, then translate the result.

Will the translated PDF look like the original?

No. The output is plain translated text, not a re-typeset PDF — the original layout, fonts, and images aren't reproduced.
