Translate PDF Online — 70+ Languages, Layout Preserved, Free
Translate a PDF using DeepL or Google Translate, with the source language auto-detected if you're not sure what it's written in. Choose Preserve Layout to keep the original page — position, size, weight, colour, images, tables and form fields — with the text translated in place; the typeface changes, because the new text is redrawn in a Unicode font so every script renders. Or choose Extract Content to reflow the translated text into a clean PDF, DOCX, CSV, JSON or TXT file.
Translation runs as a background job: upload your PDF and Dudle queues it, translates it, and shows live progress while it works. Layout, fonts and images carry over correctly on most documents, though very complex, image-heavy or unusual layouts can be harder to reflow perfectly than a straightforward text page, and larger files simply take a bit longer to finish.
No sign-up is required. Files up to 50 MB are accepted, and both your original PDF and the translated result are processed securely and deleted automatically after an hour. Nothing is installed: the whole translation runs from this page on desktop, tablet or phone.

Frequently asked questions
Is there a free way to translate a PDF online?
Yes — upload your PDF, pick a source and target language (or leave Auto-detect on), and Dudle translates it via DeepL or Google Translate for free, with no sign-up required.
Can I translate a PDF without losing the original formatting or layout?
Yes — choose Preserve Layout and Dudle returns a PDF that looks like the original, with fonts, images and form fields intact, just with the text translated. Very complex or image-heavy layouts can be somewhat harder to reflow perfectly than a plain text page.
How many languages does the translator support?
70+ — pick from a searchable list covering everything from Spanish and French to Vietnamese and Zulu, and leave the source language on Auto-detect if you're not sure what the PDF is written in.
Can I translate a scanned (image-based) PDF?
Not directly — translation reads the PDF's existing text layer, so a scanned or image-only PDF needs OCR first. Run it through Dudle's OCR PDF tool to add a searchable text layer, then translate the result.
Does translation happen instantly, or does it take time?
It runs as a background job rather than instantly — you'll see live progress while your PDF is translated, and larger or more complex documents take a bit longer than short ones.
