FAQ
Common questions
Is my audio uploaded anywhere?
No. Decoding, waveform rendering, playback, and export all happen locally in your browser.
What audio formats can I upload?
Whatever your browser's built-in audio decoder supports — most browsers handle MP3, WAV, M4A, and OGG. If a file can't be decoded, you'll see a clear message rather than a silent failure.
What format is the trimmed file?
A standard 16-bit PCM WAV file, which preserves the original sample rate and channel count and opens everywhere.
Is there a file size limit?
Yes — very large files can use more memory than a browser tab can safely handle once decoded, so extremely large uploads are rejected with a clear message.
Can I preview just my selection before exporting?
Yes. Preview Selection plays only the audio between your chosen start and end points.
