No more “your file is stored on our server”. We built the first complete PDF suite that runs entirely client‑side — meaning your sensitive data never leaves your device. From students to Fortune 500, we treat privacy as a human right.
Founded in 2022 by a team of privacy engineers and designers, we noticed that most “free” PDF tools secretly stored user files on unsecured clouds — or sold data to third parties. We set out to change that.
We rebuilt everything using WebAssembly and cutting-edge local processing. Today, PDF Official is the trusted choice for millions who want to edit, compress, sign, and convert without worrying about data leaks. Our open‑core technology stays transparent and always will be.
Certified zero‑knowledge infrastructure — ISO 27001 ready, GDPR compliant.
⚡ Fully client‑side processing
No upload = no breach. Your files never leave your browser.
Trusted by security‑first enterprises
No servers, no logs, no tracking. Your documents stay yours.
80% of our tools are 100% free — no paywalls for core features.
