Frequently asked questions
What audio formats does the cutter support?
You can cut MP3, WAV, FLAC, M4A, AAC, OGG, and OPUS files. The output format matches the input.
Can I preview my selection before cutting?
Yes. Use the Play button to listen to the selected segment before you cut it.
Will cutting reduce the audio quality?
The audio is re-encoded to ensure accurate cut points, which may slightly affect quality. For lossless formats like FLAC and WAV the quality loss is imperceptible.
Is my file uploaded to a server?
No. All processing happens locally in your browser using FFmpeg.wasm. Your audio never leaves your device.
Is there a file size limit?
There's no strict limit, but very large files (100 MB+) may slow down the browser since everything runs locally.
