Is the audio trimmer free?

Yes. It needs no account and adds no watermark.

Are my files uploaded?

No. The cut is made in your browser with FFmpeg. The files are not sent to our server.

How do I set the start and end time?

Drag the two handles, or type the times in the Start and End boxes. You can use seconds, such as 12.5, or minutes and seconds, such as 1:30. Play selection plays only the part you will keep.

What is the difference between Same format and MP3, WAV or M4A?

Same format copies the sound without re-encoding, so it is fast and does not change the quality. MP3, WAV and M4A re-encode the cut, which suits cuts that must be exact or a change of format. For a video file, Same format saves an MP3.

It is very close. In a test, a 4-second cut of a WAV and of an MP3 came out within about 10 milliseconds of 4 seconds. Some formats can only be cut at certain points when copied, so choose MP3 if you need the cut to be exact.

Why did the fast cut fail?

Some formats cannot be copied cleanly at the point you chose. The tool then re-encodes the cut as MP3 instead.

You can add a video file, but the result is audio only. This tool is not a video editor.

Can I cut a section out of the middle?

No. It keeps one part from the start time to the end time. To drop a pause in the middle, try the Silence Remover.

What is the file size limit?

About 200 MB per file. The first cut downloads the FFmpeg engine, which is about 30 MB, so it is slower than later ones.
