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.

Resize PDF pages

Make every page A4 or Letter

How it works

Make every page the same size — perfect after merging files with mixed page sizes.

  1. Add one PDF file.
  2. Choose the paper size and orientation.
  3. Pick a margin.
  4. Choose “Resize pages” and download.

Questions

Will the content be stretched?

No. Each page is scaled proportionally and centred, so nothing is distorted.

What isn’t kept?

Links, form fields and comments aren’t carried over to the resized pages; the visible page content is.

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.
