PaperKnife

Privacy-first PDF utility (Zero-Server Architecture). Merge, split, compress, and edit PDFs 100% locally on your device. No uploads, no servers, no tracking.

PaperKnife is a collection of tools that run entirely in your browser or on your phone. Your files never leave your device's memory, they aren't stored in any database, and no server ever sees them. It works 100% offline.

Features

- Modify: Merge multiple files, split pages, rotate, and rearrange. - Optimize: Reduce file size with different quality presets. - Secure: Encrypt files with passwords or remove them locally. - Convert: Convert between PDF and images (JPG/PNG) or plain text. - Sign: Add an electronic signature to your documents safely. - Sanitize: Deep clean metadata (like Author or Producer) to keep your files anonymous.
