Frequently asked questions
What audio formats can I upload?
Anything your browser can decode — MP3, WAV, M4A/AAC, OGG, and FLAC all work in most modern browsers.
How accurate is the trim?
Selection is sample-accurate — the exported file starts and ends exactly where you placed the handles, down to the audio sample.
Is my audio file uploaded anywhere?
No. The file is decoded and trimmed entirely in your browser using the Web Audio API — it never leaves your device.
