360+ private file tools that run in your browser


OpenFile is a free, open source toolbox for PDFs, images, video, audio, fonts, archives, eBooks, data and local AI. Every tool runs on your device with WebAssembly and Web Workers, so files are never uploaded. It installs as a PWA and works offline. I built it because I did not want to upload private files to random converter sites.
