About the MP3 trimmer
Cut a clean section from any MP3 or audio file. The trimmer uses stream copy whenever possible, so the output keeps the exact original quality of the input — no re-encoding required.
Use it to chop ringtones, remove silence at the start of a recording, isolate a chorus, or pull a clip out of a longer file. We don't analyse or index your file.

Trimmer FAQ
Will trimming reduce my audio quality?
No. The trimmer uses lossless stream copy where the format allows it, so the exported clip is bit-identical to the matching segment of the original.
Can I trim more than once?
Yes. Trim, download, then drop the file in again to make another cut. The tool resets in one click.
What audio formats are supported?
Common audio formats — MP3, WAV, FLAC, OGG, OPUS, AAC, M4A, AIFF and more.
Is there a maximum length?
There is no length limit beyond what available memory can hold. Most files of any reasonable length work fine.
