About PDFPup
Last updated: November 2026
PDFPup is a free collection of 40+ online PDF tools — merge, split, compress, convert, edit, sign, protect, OCR and more.
Why we built it
Most online PDF tools ask you to upload private documents to a server. PDFPup does everything inside your browser, so your files stay on your own device. It is fast, private and free for everyone.
What you can do
- Organize: merge, split, remove, extract and re-order pages
- Convert: Word, Excel, PowerPoint, JPG and HTML to and from PDF
- Edit: add text, sign, watermark, rotate, crop, redact and number pages
- Secure: protect with a password or unlock your own files
