Common Questions
Is my audio file uploaded to a server?
No. This tool works entirely in your browser using the Web Audio API. Your file never leaves your device — nothing is uploaded to any server.
Which audio formats are supported?
MP3, WAV, M4A, OGG, and AAC are supported as input. You can export the cut audio as MP3, WAV, or OGG.
Will quality be lost when cutting?
If you export as WAV, there is zero quality loss — it's lossless. MP3 and OGG involve re-encoding, but the difference is not audible in normal listening.
Can I use this on my phone?
Yes. The tool works on all modern mobile browsers. For best performance, use files under 30 MB on phones with limited RAM.
What is the maximum file size?
Up to 100 MB. Since everything runs in the browser, very large files may take a few seconds to load and process depending on your device.
