Trim audio features

• 01

  Interactive trim timeline

  Drag the start and end handles on the visual timeline instead of typing timestamps manually. Scrub the playhead, preview the selection, and fine-tune the boundaries by ear.

• 02

  Keeps the original format

  Trim an MP3 and you get an MP3 back. Trim a WAV, OGG, or M4A and the output keeps that same format, so the result drops straight into the workflow you already use.

• 03

  Private, browser-only processing

  Powered by FFmpeg compiled to WebAssembly, trimming happens entirely on your device. Your audio file is never uploaded or stored on a server.

Trim audio FAQ

How do I trim an audio file online?

Drop your audio file into the tool, drag the start and end handles on the timeline to the exact section you want, preview it with the play controls, then click Trim. Download the shortened file when it finishes.

Which audio formats are supported?

The audio trimmer works with MP3, WAV, OGG, and M4A files up to 1 GB.

Can I trim audio precisely without typing timestamps?

Yes. The tool uses an interactive timeline with draggable boundaries, so you can move the trim handles visually and preview the exact section before exporting.

Will trimming change the output format?

No. The trimmed file keeps the same format as the source file, so an MP3 stays an MP3, a WAV stays a WAV, and so on.

Is my audio uploaded anywhere?

No. Trimming runs entirely inside your browser using WebAssembly, so the file never leaves your device.
