Extension Metadata

About this extension
LocalPDF is the all-in-one, privacy-first PDF editor, reader, and organizer that runs 100% on your device. Merge, split, rearrange, rotate, fill forms, extract text with offline OCR, and read comfortably with a true eye-friendly dark mode—without ever uploading your sensitive files to any cloud or third-party server.

🔒 100% LOCAL & PRIVATE — ZERO CLOUD UPLOADS
Unlike typical web converters that upload your tax returns, legal contracts, or company documents to remote servers, LocalPDF does all processing inside your browser. No accounts, no subscriptions, no tracking, and no external API calls. Your documents never leave your computer.
