Why trim audio
Tighter listening
No one likes waiting through silence before the content starts.
Smaller files
Removing dead air at both ends trims bytes as well as seconds.
Perfect loops
Trim samples and clips to the exact boundaries you need for loops and ringtones.
Private and free
No uploads, no accounts, no watermarks, and no cost.
Why the first and last seconds matter
The beginning and end of a recording carry more weight than you might think. A clip that starts with three seconds of hiss and fumbling makes the listener check their connection, while a clean start lands instantly. Trimming those edges is the single fastest improvement you can make to any audio.
Trimming is non-destructive to the content you keep - the middle of the recording is copied sample for sample with no re-encoding to a lossy format. That means the part you keep sounds exactly like the original.
When trimming, leave a small natural breath at the start and end rather than cutting to the exact first and last waveform peak. A tiny bit of room sounds more natural than a razor-thin edit.

Frequently asked questions
How does this audio trimmer work?
You set a start and end point on a waveform, and the tool keeps only the audio between those points.
Which formats can I trim?
MP3, WAV and OGG inputs are supported, and the result downloads as a lossless WAV file.
How precise is the trim?
You can adjust the start and end points in 0.1-second steps for accurate edits.
Will trimming reduce quality?
No. The kept portion is copied without lossy re-encoding, so it sounds exactly like the original.
Is there a file size limit?
Files up to 100 MB are supported, which covers most recordings and songs.
Are my files uploaded anywhere?
No. Trimming runs entirely in your browser, so your audio never leaves your device.
