Unique PDF

What is Unique PDF?

Unique PDF is a free, forever PDF editor for Chrome. It puts 20 tools in one tab: Chat with PDF, AI Summary, Merge, Split, Organize, Rotate, Reorder, Delete, Extract pages, Compress, Images to PDF, PDF to images, Edit, Sign, Watermark, Page numbers, Protect (AES-256), Unlock, Redact, and Edit metadata.

Every tool processes files on your device. Nothing is uploaded to Unique Labs or any other server. There is no sign-up, no paywall, no daily limit and no watermark. After install, the PDF tools work offline. The extension asks for one permission only (storing settings) and includes no analytics or tracking. Dark mode and a Ctrl+K (Cmd+K) command palette are built in.

Chat with PDF and AI Summary use Chrome's built-in AI on desktop Chrome 138 or newer. Answers include page references so you can verify the source. On computers without Chrome's built-in AI, chat falls back to labelled text search and a non-AI quick summary.

Made by Unique Labs, developed by Shahriar Ahmed in Dhaka, Bangladesh.
