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.

Split a PDF by page ranges

Break a PDF into separate files

How it works

Turn one PDF into several smaller PDFs. Enter ranges like “1-3, 5, 7-9” and each range becomes its own downloadable file.

  1. Add one PDF file.
  2. Enter page ranges, separated by commas — for example “1-3, 5”. Page numbers start at 1.
  3. Choose “Split PDF”. Each range is generated as its own PDF.
  4. Download each new file from the results list.

Questions

What range formats are accepted?

Single pages (“5”), ranges (“2-6”), or a mix separated by commas (“1-3, 5, 8-10”). Pages cannot appear in two ranges, and every page must exist in the document.

Can I split a password-protected PDF?

Not directly. Open it in the Unlock tool first (you’ll need its password), then split the unlocked copy.

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.
