About HushPDF

Private by design

  • Files are processed in your browser — never uploaded, tracked, or stored.
  • Free & open source (MIT) — audit, self-host, or fork it.

Limitations

  • Password-protected PDFs aren’t supported.
  • Up to 50 MB per file (150 MB total when merging).
  • It edits the finished PDF, not the Word or design file it was made from.
  • Forms, annotations, or signatures may not carry over when pages are copied.
  • Signatures are images (e-signatures), not certificate-based digital signatures.
  • Typed text supports Latin, Greek, Cyrillic, Bengali, Devanagari and Arabic.
  • Compression helps most with scanned or image-heavy PDFs.
  • OCR (beta) downloads a language model on first use; your pages stay on your device.
