FAQ
What audio formats can I upload?
Any format your browser can decode, including MP3, WAV, M4A, and OGG. The trimmed clip is always exported as a WAV file.
Is my audio file uploaded to a server?
No. The file is decoded and trimmed entirely in your browser with the Web Audio API. It never leaves your device.
Why does the download come out as a WAV instead of my original format?
The trimmed audio samples are re-encoded as uncompressed 16-bit PCM WAV, which any browser-based tool can build without extra libraries and which every audio app can open.
