Privacy First
True Client-Side Architecture
PDFTools is built on a "Local-Only" principle. When you use our tools, your browser downloads a compact, high-performance processing engine. This engine does all the work right in your device's memory.
- Zero Server Storage: Since nothing is uploaded, there's nothing for us (or anyone else) to store or leak.
- Offline Capability: Once the page is loaded, most tools can work even if your internet connection drops.
- RAM-Only Processing: Files are processed in volatile memory and never touch a physical disk outside your device.

Performance
Blazing Fast WASM Engine
Our tools are powered by WebAssembly (WASM), which allows C++ and Rust-based processing libraries to run at near-native speeds directly in your browser.
- No Upload Latency: Skip the long wait times associated with uploading large PDF files to remote servers.
- Instant Results: Most operations, like merging or rotating, happen in the blink of an eye.
- Multi-Threaded: We leverage modern browser capabilities to process complex tasks in parallel.
Near-Native Performance
