Security at PDFree

Most PDFree tools process your PDFs entirely inside your browser using WebAssembly. Your files are never uploaded to a server — they exist only in your device’s memory for the duration of the operation and are discarded the moment you close the tab or navigate away. This means zero exposure to network interception, zero server-side storage, and complete control over your documents at all times.

Two tools — Protect (password encryption) and Unlock (password removal) — require brief server-side processing because the underlying cryptographic operations are not yet fully supported in browsers. When you use these tools, your file is encrypted in transit over HTTPS, processed in an isolated environment, and deleted immediately after the result is returned. We never store your files, and we never log file contents or metadata.

PDFree does not require registration, login, or any form of personal identification. We do not track which documents you process. The only cookies we use are for anonymous analytics, and those are activated only after your explicit consent. Rate limiting is enforced by an anonymized IP hash — we never build user profiles or store browsing histories.

PDFree is designed with the EU General Data Protection Regulation at its core. We follow the principle of data minimization: we collect no personal data, store no documents, and require no accounts. Cookie consent is always required before any analytics script loads. You can review our full privacy practices in our Privacy Policy.

Transparency is a cornerstone of trust. PDFree’s source code is publicly available and auditable, so you can verify our security claims for yourself. We welcome community review, bug reports, and contributions.
