Free private local English to French PDF translator

A English to French PDF translator extracts text glyphs from your English document, translates them into French using local AI, and renders the translated text directly back into the original layout. Everything runs in your browser without uploading the file.

Drop your file into the tool above. The language selector is already locked to English → French. The document is read with pdf.js, grouped into complete paragraphs, and translated by on-device models. No server requests carry your content.

French expands roughly 15–20% against English and uses non-breaking spaces before punctuation such as « : » and « ! », which survive extraction intact. The on-page reader scales font sizes proportionally within original bounding boxes to keep the translated French layout faithful without text clipping.

Most academic and technical PDFs are already typeset in English, which makes it the most common target for documents people need to actually work with. Clean digital exports from word processors or desktop publishers produce high-accuracy results. Scanned pages are automatically detected and processed via on-device OCR.

The translation model runs directly on your machine via WebAssembly or Chromium's built-in translator. Once cached, you can translate English documents to French with no internet connection.

The reader provides three views: Side by side pairs every translated paragraph next to its English original with synchronous cursor highlighting; On the page overlays the translation with instant hover peek to reveal original text; and Translation provides clean reading text.

Yes. Client contracts, medical documents, research papers and internal reports never leave your computer. You can monitor your browser DevTools Network tab during translation to confirm zero file uploads.
