About This Tool
This tool uses the browser's Web Audio API to decode your audio file, extract the selected time range, and re-encode it as a WAV file — all inside your browser. No files are uploaded. The output is always WAV (lossless PCM) for maximum compatibility.

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.
Can I cut MP3 files on mobile?
Yes. The tool works in modern mobile browsers, but very large files may be limited by your phone's available memory.
Why is the download a WAV file?
The browser decodes audio into raw PCM samples and exports the selected range as WAV. WAV is lossless and widely compatible, but it can be larger than compressed formats like MP3.
