About

Why BlitzTools PDF?

Privacy by Design

Your PDF files never leave your device. All processing happens in your browser using WebAssembly. There are no uploads, no server-side processing, and no data collection. This is fundamentally different from cloud-based PDF tools that require you to upload sensitive documents.

No Limits, No Sign-Up

• No file size limits (constrained only by your device memory)
• No daily usage caps
• No account registration
• No watermarks on output

Performance

Built with Rust compiled to WebAssembly, BlitzTools PDF processing runs at near-native speeds. The WASM engine handles complex operations like PDF rendering, text extraction, and compression directly in the browser.

Works Offline

Once loaded, BlitzTools PDF Tools work without an internet connection via service workers. Process PDFs on a plane, in a meeting, or anywhere without connectivity.

All Platforms

Works on any modern browser — Chrome, Firefox, Safari, Edge. Desktop and mobile. No software to install.
