Clean output, every time.
Sometimes you only need a piece of an audio file — a ringtone, a single quote, the chorus of a song, or the useful part of a long recording. An audio trimmer lets you keep just that section and drop the rest.
Set a start and end time and the trimmer cuts your clip and saves it as an MP3 — all in your browser, with nothing uploaded. It also works on video files, taking the audio between your chosen times.

Cutting a clip out of a recording
Set a start time and an end time, and everything outside that window is dropped. It is the fastest way to get to the part that matters: the answer in a long interview, the chorus of a track, the ten minutes of a two-hour recording that anyone will actually listen to.
Trimming does not modify your original file. The clip is written out as a new file, so you can cut several different sections from the same recording without ever risking the source.
Getting the cut in the right place
- Leave a little air
- Starting a fraction of a second early avoids clipping the first syllable, which is the most common mistake.
- Cut on silence where you can
- A cut in a natural pause is invisible. A cut mid-word is the first thing a listener notices.
- Note times as you listen
- Playing through once and writing down the timestamps beats hunting for them with the scrubber.
- Trim before converting
- Cutting first means less audio to encode, so any later conversion finishes faster.

Frequently asked questions
How do I enter the times?
Use whole seconds (e.g. 45) or a MM:SS / HH:MM:SS timestamp (e.g. 1:30). Leave the end time blank to trim from your start point to the end of the file.
What format is the clip?
The trimmed clip is saved as an MP3, which plays on virtually any device or app.
Is my file uploaded?
No. Trimming happens in your browser, so your audio or video never leaves your device.
Can I trim the audio from a video?
Yes. Drop in a video file and the trimmer will cut the audio between your start and end times.
