Description

PDF reader that intercepts PDF navigations and renders them locally with a built-in PDF.js viewer. No data leaves your browser. Freedom PDF Viewer is a lightning-fast, ultra-lightweight PDF reader, editor, and organizer built directly into Google Chrome. Designed from the ground up for maximum privacy, speed, and offline convenience, it intercepts standard PDF navigations and handles them completely within your browser sandbox. Whether you need to review documents, sign contracts, merge pages, apply watermarks, or listen to papers read aloud, Freedom PDF Viewer does it all natively, locally, and offline. Your files never touch a server, and no personal data is ever collected. <hr /> <h2>🔒 100% Private, Secure, and Offline</h2> Most web-based PDF editors require uploading your confidential documents to external cloud servers.
