The converters on the web, the yoink in the app. Free.
Free, signed and notarized. macOS 12 or newer.



Like the website, nothing ever leaves your machine. No uploads, no accounts, no telemetry, no ads. Files convert on your own CPU and stay in your folders. It even bundles ffmpeg and yt-dlp, so there is nothing else to install.
Both are built and published on GitHub Releases, but nobody has run them yet. The code is portable Rust so they ought to work, though nothing on those platforms has been tested. The Windows build is unsigned too, so SmartScreen will warn you once. Bug reports welcome.
