Convert FLAC
Lossless compressed audio. Every pair below runs in the browser. The file is not uploaded. Video and audio use FFmpeg in WebAssembly, fetched from this origin once, about 30 MB, then cached by the service worker. The clip itself is not part of that download.
This hub is the index, not the workbench. Each conversion is its own URL so a search for “FLAC to something” can land on a page that only does that job. The file picker on those pages expects FLAC when you are leaving this format, or produces FLAC when you are arriving. A generic dropdown still exists under Video convert and Audio convert if you would rather pick the destination after you drop the file.
You can check the same way on every pair: open the network panel, drop a FLAC file, convert it. You should see this origin. You shouldn't see a POST of the file. Google Analytics, if it's on, is page views, not your FLAC bytes. If a tool needs a server, it isn't on this site.
This site can read it. This site can write it. Engine: ffmpeg.
