How do I use Compress audio?
Drop your files, choose the target format, and press Convert — you get clean results to download in seconds. Drop an audio file, choose the one option that matters, and download the result in seconds. Conversions keep the audio clean with no re-encode artefacts at sensible settings, and FLAC or WAV masters come down to a share-ready MP3 or M4A without a fuss. The encoding happens on your own machine: your browser fetches the ffmpeg engine once (about 31 MB) and works locally, so the track never travels to us and there is nothing on our servers to delete. The free tier handles files up to 200 MB; a paid plan lifts the cap to 2 GB per file.
