How to Trim Audio in Your Browser
Drop in your audio file
Add an MP3, WAV, M4A, AAC, OGG, or FLAC file up to 100MB — a song, a recording, a podcast, or a voice memo. It loads straight into your browser.
Set the start and end points
Drag the start and end handles to mark exactly the section you want to keep. The selection length updates as you move them.
Trim and download
The in-browser engine cuts the clip and hands it back in the same format. Preview it on the page, then download with one click — nothing is uploaded.
Everything You Need to Trim Audio
A good audio trimmer makes a clean cut, keeps your format, and never touches a server. Here's how this one does all three.
Precise start and end control
Set the in and out points to a tenth of a second, so you keep exactly the part you want and drop the rest.
Keeps your original format
Trim MP3, WAV, M4A, AAC, OGG, or FLAC and get the same format back — lossless formats are cut without re-encoding.
Built-in preview
Play the original before cutting and the trimmed result after, right on the page, so you can confirm the cut before downloading.
No upload — 100% private
Everything runs in your browser tab. Recordings and music never leave your device, so there's nothing to leak or retain.
When You Need to Trim Audio
Cutting a clip down is one of the most common audio jobs. These are the moments a trimmer helps.
Make a ringtone
Cut a favorite few seconds out of a song to use as a ringtone or notification sound, without any editing software.
Clean up a recording
Remove silence, false starts, or dead air from the beginning and end of an interview, lecture, or voice memo.
Grab a sample or clip
Pull a short quote, sound bite, or musical phrase out of a longer file to share or reuse.
Fit a length limit
Trim audio to fit a platform's maximum duration for a status, story, or upload without re-recording.
Trim Audio Without Uploading Your Files
Most online audio cutters upload your file to a server, trim it there, and hand back a download. Doing it locally is private and faster.

Pro Tips for Trimming Audio
Trim lossless formats to avoid re-encoding
WAV and FLAC are cut without re-compressing, so the trimmed clip keeps the exact quality of the source.
Leave a little breathing room
Set your start slightly before and end slightly after the part you want, so the cut doesn't clip the first or last word.
Preview before you download
Play the trimmed result on the page first — it's faster to nudge the handles than to re-cut after downloading.
