About this tool

Translate PDF — Keep the Layout, Translate on Your Device

Translate the text of a PDF into another language and keep its layout: each paragraph is set back into its own lines. Everything runs locally in your browser — no upload, no sign-up, no watermark and no file size limit.

Layout Stays in Place

Paragraphs are translated as a whole, so sentences that run over several lines come out right, then wrapped back into the original lines. A longer translation is set a little smaller instead of spilling over.

Translated on Your Device

Chrome and Edge use their built-in translator. Other browsers download an open Firefox Translations language pack once, checked against Mozilla's checksums and kept in the browser; the text itself is never sent anywhere.

Review Every Paragraph

Translated paragraphs are listed for review. Click a line to adjust the wording, or undo the whole run in one step.

How to use it

  1. Drop the PDF. The editor opens in Translate mode.
  2. Check the source language (it is detected automatically) and pick the target language.
  3. Click Translate page, or Translate all pages for the whole document. The first run may download a language pack.
  4. Read through the translated paragraphs and click any line to adjust it.
  5. Download the edited PDF.

Frequently asked questions

Are my PDFs uploaded to a server?

No. Toolula processes the document inside your browser tab with pdf-lib and WebAssembly, so the file never leaves your device.

Which languages can it translate?

Target languages include English, German, French, Spanish, Italian, Dutch, Portuguese, Polish, Danish, Swedish, Finnish, Norwegian, Czech, Romanian, Russian, Turkish, Arabic, Chinese, Japanese and Korean. Which pairs work depends on your browser; if one isn't available, Toolula tells you.

Does the translation keep the original font?

Where the PDF contains the original font with every letter the translation needs, the lines are redrawn in it. Otherwise a font with matching letter widths is used.

Is it as good as a human translation?

No. It is machine translation, good for understanding a document or a first draft. Have contracts and official documents checked by a person.

Is it really free?

Yes. You can use every Toolula PDF tool for free, without an account. The free plan has fair-use limits; Toolula Pro, an optional plan, raises them and adds advanced features.
