How to translate a PDF for free?

Upload your PDF, select source and target languages (or use auto-detect), and click Translate. The tool processes everything in your browser — no signup, no payment, no file upload to any server.

Which languages are supported?

20 languages are available in the selector. The bundled translation models currently focus on English-to-language and language-to-English pairs, so arbitrary non-English pairs may not be available.

Is my PDF uploaded to a server?

The PDF text extraction, translation, and output PDF are performed in your browser. The translation library, model files, and PDF worker may be downloaded from public CDNs on first use; your document is not sent to a FileForge backend.

Does it work offline?

The translation model can be reused from browser cache after it has downloaded, but first-time setup and some browser workers may require internet access. Offline support is not guaranteed after cache eviction.

Is the layout preserved?

The translated text is rebuilt into a clean, readable A4 PDF. Complex layouts with tables, images, or columns may be simplified to focus on text content.

How accurate is the translation?

The tool uses Helsinki-NLP neural machine translation models, which provide high-quality translations for common language pairs. For professional or legal documents, we recommend having a human review the output.

Can I translate a scanned PDF?

This tool works with text-based PDFs. Scanned PDFs (images of text) require OCR first. If your PDF has no extractable text, you will see an error message.
