Cut a piece out of an audio file

Drag the two ends, keep the middle. Nothing is re-encoded, so the piece you get is identical to the original.

Your file never leaves this tab: it's processed by your own browser and nothing is uploaded to us. You can go offline once the page has loaded and it still works.

Almost every recording has a beginning nobody needs: two minutes of people arriving, the microphone being adjusted, the «can you hear me?». And usually an end just as useless. Cutting that off isn't editing — it's the thing you do before doing anything else with the file, and it shouldn't require installing an audio editor.

This one doesn't re-encode: it copies the piece you marked, byte for byte, into a new file of the same format. That means two things. It's instant, even on a two-hour recording, because there's nothing to compute. And it's lossless — the cut piece sounds exactly like it did inside the original, which is not true of a trimmer that decodes and re-encodes on the way through.

What we handle that others don't

  • It copies instead of re-encoding: the cut is instant and loses nothing at all.
  • The output keeps the original format — an MP3 comes out an MP3, a WAV a WAV — so nothing downstream has to be told anything new.
  • A player right there, so you can find the exact moment instead of guessing at numbers.
  • Nothing is uploaded. A two-hour recording is cut without a single megabyte crossing the network.
