About This Tool

Frequently Asked Questions
Is my audio uploaded to a server?
No. All audio cutting is done using the Web Audio API which runs entirely in your browser. Your files never leave your device and are never transmitted to any server.
What formats are supported?
The audio cutter supports MP3, WAV, OGG, FLAC, AAC, M4A, and other common audio formats that your browser can decode.
Will cutting reduce audio quality?
The selected range is exported as lossless WAV audio. This avoids extra lossy compression, though the downloaded file may be larger than the original MP3 or AAC file.
