Why is this server-side?

Re-encoding to arbitrary bitrates efficiently requires ffmpeg, which is not available in the browser without shipping a very large WebAssembly build.

Do you keep my files?

No. Uploads are processed in-memory and deleted as soon as the result is returned.

Submit
The file uploads to the MakeMySounds server, where ffmpeg re-encodes it and returns the result.
Download
