FAQ
Common questions
Is the audio cutter free?
Yes — trimming audio is completely free, with no sign-up, no watermark, and no limit on how many files you cut.
What file types can I trim?
MP3 and WAV files up to 10 minutes long. Longer files aren't supported yet.
Does trimming lose audio quality?
No — the cutter trims the file without re-encoding the parts you keep, so quality stays the same.
Can I split the trimmed file into vocals and instruments too?
Yes — trim it here first, then run the result through the AI vocal remover and splitter on the homepage.
