About PDF Tools
PDF Tools is a free, browser-based suite for working with PDF files. Split, merge, compress, convert, edit, sign, and more — all without uploading a single file.
Privacy-First by Design
Unlike most online PDF tools, your files never leave your device. All processing happens locally in your web browser using JavaScript. There are no servers receiving your documents, no cloud storage, and no data retention. When you close the tab, your files are gone from our site entirely — because they were never here.
How It Works
PDF Tools leverages modern web technologies to process PDFs directly in your browser:
- PDF-lib — for splitting, merging, rotating, watermarking, and page manipulation
- Canvas API — for rendering, cropping, and image conversion
- JavaScript — all tool logic runs client-side, meaning zero server interaction
This means the tools work offline once the page loads, and performance scales with your device rather than a remote server.
