Open tool →How it works
- Pick a tool and drop your file. Nothing is uploaded — the file is read straight from disk by your browser.
- It processes on your device. PDF rendering runs on PDF.js, structural optimization on a small Rust/WASM core, and image codecs are your browser's native (SIMD-accelerated) ones.
- Download the result. When you close the tab, no trace of your document remains anywhere — not on this site, not on a server, because there is no server.
