Trim audio

How it works

1. 1

   Add your audio

   Drop an MP3, M4A, WAV, FLAC, or OGG. It stays on your device.

2. 2

   Set in and out

   The waveform shows the sound; click it to listen from any point, then set the range.

3. 3

   Download

   Just the part you kept, a lossless copy where the format allows. No watermark.

Cutting audio cleanly, and why cuts click

Audio is a waveform, and a cut placed anywhere in it is a vertical jump from whatever the sample value happened to be straight to silence. Your speakers reproduce that jump faithfully, and a jump that steep is heard as a click or a pop. It is the single most common flaw in hand cut audio, and it has nothing to do with the quality of the recording.

The fix is a very short fade across the boundary, a few milliseconds at each end, which is far too brief to hear as a fade but long enough to bring the waveform to zero gracefully instead of dropping it. That is why a clean cut sounds like nothing at all happened, which is exactly the goal.

Where you place the cut matters too. A breath before a sentence, or the tail of a room's reverb after one, is the difference between a clip that sounds edited and one that sounds recorded. Leave a fraction of a second of room tone on either side rather than cutting hard against the first and last syllables.

Trim audio in the browser, with nothing uploaded

The waveform you scrub is drawn from the file on your disk, and the cut is made on your own machine. No upload, no length limit, no watermark, and no audio tag announcing which website processed it.

Recordings are among the most private files people own. Interviews, voice notes, therapy sessions, calls, and lecture captures all end up in audio trimmers, and none of them need to be handed to a server to have thirty seconds taken off the front.

To turn the passage you keep into a phone ringtone, complete with the length limits and format each platform demands, the ringtone maker takes it from here. If the source is still a video, extract the audio first.

Why nothing uploads

Other tools send your video to their servers, which costs them money per file, so they add watermarks, cap file sizes, and make you sign up. This tool does the work right here in your browser using your own device. Your file is never uploaded, so there is no wait, no watermark, no size limit, and no account.

Questions

Does trimming re-encode my audio?

Usually not: MP3, M4A, WAV, FLAC, and OGG cuts are stream copies, instant and lossless. Unusual formats are re-encoded to high-quality M4A.

How precise is the cut?

To a tenth of a second with the sliders. Click the waveform to audition exactly where the cut lands before committing.

Can I trim a voice memo or WhatsApp audio?

Yes, those are M4A/OGG files, which trim losslessly here.

Does my audio get uploaded?

No. Trimming happens in your browser; the file never leaves your device.

Is there a watermark or limit?

No. No watermark, no spoken tag spliced onto the file, no signup, and no cap on the length of the recording you trim.
