Frequently asked questions
- Is my audio uploaded anywhere?
- No. Reversal runs entirely in your browser with ffmpeg.wasm — the file never leaves your device.
- Which formats are supported?
- Any format ffmpeg supports: MP3, WAV, OGG, M4A, FLAC, AAC, and more. The output keeps the same format as the input.
- How long does it take?
- Usually a few seconds for short files. Longer files may take longer as everything happens in-browser.
