Frequently asked questions
What files can I use here?
Reads MP3, M4A, WAV, OGG and 4 more formats. As many files at once as you like.
What do I get back?
You get MP3 · WAV · OGG · FLAC.
Does the file lose quality?
The sound is decoded and encoded again. At high bitrates that is inaudible; low ones thin out cymbals and sibilants first.
When does it not work?
Which audio codecs work depends on your browser. MP3, WAV and OGG are safe everywhere; AAC and Opus depend on the machine.
Which bitrate should I pick?
192 kbps sounds transparent to most ears, 128 kbps is the classic size for sharing, and 96 kbps still fits almost any inbox. Going higher than the original never adds quality — it only adds bytes.
Does the length change?
No. Converting and compressing keep the full length; only trimming shortens the file, and there you set the start and end yourself.
