Drop on MP3

What Filee does for WAV → MP3
A WAV recording takes about 10 MB per minute; as MP3 it needs a fraction of that and still plays on every device.
- Uses FFmpeg, a free optional engine that Filee downloads once into its own folder (about 100 MB). Programs installed on your PC are never used.
- The MP3 128k preset makes smaller files, ideal for speech.
- Batch: one file or hundreds, converted in parallel; a failure never stops the rest.
- Private: files are converted on your PC and never uploaded, even without internet.
- Saved next to the original, or in a folder and with a file name pattern you choose.
WAV can also become
- M4A
- FLAC
- OGG
- OPUS
- AAC
