Audio Trimmer
Cut a clip out of an audio file โ trimmed on your device.
Trimming a clip
Drop in an audio file โ MP3, M4A, WAV, OGG โ and its waveform appears. Drag across it to select, nudge the edges or type exact seconds, audition with play-selection, and download the cut as a WAV. Decoding and cutting happen entirely in your browser: a big file costs memory, never bandwidth, and nothing is uploaded.
Why the output is WAV, and what to do with it
Browsers can decode MP3 but cannot encode it, and re-encoding lossy audio would cost quality anyway โ so the honest export is WAV: uncompressed, universally accepted, about 10 MB per stereo minute. Every editor imports it, and Android accepts a WAV directly as a ringtone; iPhones route ringtones through GarageBand or a computer regardless of which tool cut the clip.
Trimming is the whole edit here โ no fades, effects or multitrack, which keeps it instant for the common jobs: cutting a clip for a ringtone, trimming silence off a voice recording, extracting a quote from a long file. The compression guide explains the lossy/lossless trade-off behind the WAV decision, and recordings to trim can come from the screen or webcam recorders' audio too.
Frequently asked questions
How do I cut a section out of an MP3?
Drop the file in, drag across the waveform to select the part to keep, fine-tune the edges, and download. The clip exports as WAV.
Why does it export WAV instead of MP3?
Browsers cannot encode MP3, and re-encoding lossy audio loses quality anyway. WAV is lossless and universally accepted โ convert afterwards if size matters.
Is there a file size limit?
Only your device's memory โ the file is decoded locally. A one-hour MP3 decodes to roughly 600 MB in memory, which modern devices handle.
Can I use the clip as a ringtone?
Android: yes, a WAV works directly. iPhone: ringtones must pass through GarageBand or a computer whatever tool made the clip โ Apple's rule, not the file's.
