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.

Add header & footer

Add text to the top or bottom

How it works

Put text at the top or bottom of every page — with automatic page numbers, dates and the file name.

  1. Add one PDF file.
  2. Type into any of the six header/footer boxes.
  3. Use {page}, {total}, {date} and {file} for automatic values.
  4. Download the result.

Questions

What do the tokens do?

{page} becomes the page number, {total} the page count, {date} today’s date and {file} the file name.

Can I skip the cover page?

Yes — turn on “Skip the first page”.

Are my files uploaded to a server?

No. Every operation runs locally in your browser using JavaScript (pdf-lib, with page previews from PDF.js). Your documents are never transmitted to us or to any third party, and there are no accounts, watermarks, or file-retention tricks. You can even disconnect from the internet after the page loads and the tools still work.
