Comments
Hi Fazier! I built NativeConvert because every online converter I tried uploaded my files to its servers first. NativeConvert does the work inside your browser tab with WebAssembly (FFmpeg.wasm, pdf.js, Whisper and others), so photos, PDFs and recordings never leave your device. You can check it yourself: open DevTools, Network tab, and convert a file. Honest limits: very large videos are slower than on a server, and there is no Word to PDF yet. Feedback very welcome!
