Does the cutter upload my file?

No. The entire cut runs client-side using the Web Audio API and OfflineAudioContext. Your audio never leaves the browser.

Which formats are supported?

MP3 and WAV input work everywhere. Other formats depend on your browser — if decoding fails, try the server-side trimmer at /audio-trim instead.

Yes, 100 MB per file. Larger files should be compressed first via the format converter or use the server-side trimmer.

WAV export is lossless. MP3 export re-encodes at 128 kbps, which is a good balance of size and quality for most material.

Trim MP3 and WAV files by selecting a start and end point on the waveform.
