What is nouploadpdf.org?

A free, browser-only PDF editor that processes merges, splits, compressions locally — no servers, no uploads.

Is nouploadpdf safe for sensitive documents?

Yes — files stay on-device, processed in memory, deleted on tab close. Beats uploading to third-parties.

Small ones fly; 50MB+ slows on weaker hardware due to browser limits, but viable for most users.

Upload your resume to a random PDF merger? Risky bet. One dev's client-side tool fixes that — entirely in-browser, zero servers.
