What compressing audio actually does
Whatever audio you feed it: MP3, WAV, FLAC, M4A, the lot: Flippy re-encodes at the bitrate you pick. Savings depend on the source: uncompressed and lossless files give up the most (a WAV can lose 90%), while voice recordings can go far lower than music before anyone notices. Not sure? The medium preset is the sweet spot.

Questions people ask
How much smaller will my audio file get?
It depends on the format it arrives in: uncompressed sources give up the most, already-lossy ones the least. Most files land 30–70% smaller at the medium preset before quality visibly suffers.
Will I lose quality working with audio here?
Where possible Flippy copies streams without re-encoding; when a re-encode is unavoidable it happens once, at quality matched to your audio.
Is this audio compressor really free?
Yes: free for everyday use with no daily cap, no signup, and your files delete themselves from our servers within an hour.
