Cut any audio file in your browser: drop it, drag the start and end points on the waveform, preview the edges, download a lossless WAV of the selection. Nothing uploads - it works offline.

MP3, WAV, AAC/M4A, OGG - decoded locally, never uploaded
Cut on silence or just before a transient (a drum hit, a word's consonant) and the edit is inaudible; cut mid-note and you get a click. The waveform shows you where the quiet moments are - aim your handles at the valleys. For changing a clip's tempo or key rather than its length, use the speed changer; to check levels on the result, the audio analyzer reads LUFS and true peak.
Drop the file here, drag the start and end sliders until the highlighted region covers what you want to keep, hit preview to check the edges, and download. The file decodes and exports entirely in your browser - nothing is uploaded, so a 50 MB file trims as fast as your machine allows.
Anything your browser can play: MP3, WAV, AAC/M4A, OGG, and in most browsers FLAC. The trimmed export is always an uncompressed 16-bit WAV at the source sample rate - lossless from the decode onward, and accepted by every editor, DAW, and player.
Browsers decode MP3 natively but do not encode it. Rather than ship a multi-megabyte encoder or round-trip your audio through a server, this tool exports lossless WAV. If you need MP3 for size reasons, convert the WAV afterwards - you lose nothing by trimming first.
No. Decoding, trimming, preview, and export all happen locally with the Web Audio API. The page works offline once loaded, and your audio never leaves your device.
Yes - trim to under 30 seconds and export. iPhones want ringtones in M4R (convert the WAV in iTunes/Finder or GarageBand); Android accepts WAV and MP3 directly in most ringtone pickers.
