Trim Audio

Cut an audio clip between a start and end time.

Audio file

Choose a file to convert. It's processed locally — never uploaded. Tip: add several files to convert them all at once.

{ } How to use

  1. Choose the audio file.
  2. Enter the start and end times, in seconds or as hh:mm:ss.
  3. Select Process, then download the clip.

{ } How it works

Trim Audio works on the file you upload. Adjust the options, then select Process ▸ and it runs entirely in your browser — nothing is uploaded to a server — then shows the result in the Output panel.

Inputs

  • Audio file — upload a file (audio/*); it is read locally in your browser
  • Start (s or hh:mm:ss) — a value (default: "0")
  • End (s or hh:mm:ss) — a value (default: "30")

Output

A downloadable MP3 file — use the Download button in the Output panel.

{ } Common uses

  • Cut a section out of a long recording or an interview.
  • Make a short sample from a track.
  • Trim silence off the start or the end of a recording.

{ } Limitations

  • The audio is copied rather than re-encoded, which keeps it lossless and fast — and means a cut can only land on a frame boundary, so the start and end can be off by a fraction of a second. That is small for audio, but it is not sample-accurate.
  • The format is read from the file’s own bytes and kept: MP3, M4A, WAV, OGG and FLAC are all trimmed as they are. Anything else is re-encoded to MP3, which is lossy but always works.
  • An end time beyond the end of the file just gives you the rest of it. A start beyond the end produces nothing, and the tool tells you so.

{ } FAQ

Is my data uploaded to a server?

No. Everything runs locally in your browser — your files never leave your device.

Can I process more than one file at once?

Yes — add several files and they’re all processed and downloaded together as a ZIP.

Is this tool free?

Yes — it’s completely free and needs no sign-up.

Can I trim to an exact sample?

No. Trimming copies the compressed audio instead of decoding it, so cuts land on frame boundaries — a fraction of a second, not a sample. That is the trade for keeping the audio bit-for-bit identical and finishing almost instantly. Sample-accurate editing needs a proper audio editor.
