MP3 Cutter

Cut any MP3 in your browser: drop the file, drag the start and end handles on the waveform, preview, and download the cut as MP3 (pick the bitrate) or lossless WAV. Nothing uploads.

Cutting without quality loss

Every MP3 cut here is decoded once and re-encoded once - the same single generation of loss as any MP3 editor, inaudible at 192-320 kbps. Cut on a quiet moment or just before a drum hit and the edit itself is seamless; the waveform shows you the valleys to aim for. Making a phone ringtone? The ringtone maker adds fades and length guidance. Need a different container entirely? The audio converter handles format changes, and the volume booster fixes a cut that came out too quiet.

FAQ

How do I cut an MP3 file online?

Drop the MP3 here, drag the two handles until the highlighted region covers what you want to keep, hit preview to check the edges, choose MP3 or WAV, and download. Decoding, cutting, and encoding all run in your browser - a 100 MB file cuts as fast as your machine allows, with no upload wait.

Does cutting an MP3 reduce its quality?

One generation: the file is decoded and the cut re-encoded once, exactly like any MP3 editor that does real cuts. At 192 or 320 kbps the difference is inaudible to almost everyone. If you plan further editing, export WAV instead - it is lossless from the decode onward.

What is the maximum file size?

Whatever your device can decode into memory - in practice hours of audio. Because nothing uploads, there is no server-side cap, no queue, and no premium tier: the limits of your own machine are the only limits.

Can I cut other formats than MP3?

Yes - anything your browser decodes loads fine: WAV, AAC/M4A, OGG, and FLAC in most browsers. The export is MP3 or WAV regardless of input, so this page doubles as a cut-and-convert step.

Is my file uploaded anywhere?

No. The file is decoded with the Web Audio API and encoded with a JavaScript MP3 encoder, entirely on your device. The page works offline once loaded.
