No. PDF text extraction happens entirely in your browser using PDF.js — your file never leaves your device. Only the extracted text is sent to the MyMemory translation API over HTTPS. No PDF bytes are ever transmitted.

Over 100 languages via the free MyMemory API, including English, French, Spanish, German, Dutch, Italian, Portuguese, Japanese, Chinese (Simplified & Traditional), Korean, Arabic, Russian, Hindi, Turkish, Polish, Swedish, and many more.

The tool uses PDF.js — the same library Mozilla uses in Firefox — to parse the PDF in your browser and extract the raw text content from each page. Scanned PDFs (image-only PDFs with no selectable text) cannot be translated since there is no text layer to extract.

Scanned PDFs contain images of text, not actual text data. This tool requires a text layer in the PDF. To translate a scanned document, first run it through an OCR tool to convert the images to selectable text, then upload it here.

No hard limit on pages, but the MyMemory free API has a daily character quota. For very large documents, translate page ranges rather than all pages at once using the From/To fields in the sidebar.
