Engineering
Excellence.
We stripped away the server. By moving processing to your browser via WebAssembly, we eliminated upload times, bandwidth costs, and privacy risks. Compliance teams finally get conversion super powers without data leaving their network perimeter.
Privacy First
Files never leave your device. The conversion happens in a sandboxed worker thread within your browser memory.
WASM Engine
Powered by FFmpeg compiled to WebAssembly. Multithreaded performance that utilizes your device's full capability.
Instant Feedback
No queueing. No "server busy". Drag, drop, and done. The speed limit is your CPU, not our internet connection.
