About Helpdf

Helpdf was built with one simple idea: editing a PDF should never require sending your documents to a stranger’s server.

All Helpdf tools — merge, split, compress, rotate, convert and more — run directly in your web browser using modern web technologies. Your files are read and transformed on your own device, then saved back to it. They are never uploaded, never stored and never seen by us.

Free for everyone

Helpdf is free, with no account, no daily limit and no watermark. The site is funded by advertising, which lets us keep every tool free.
