Cut segments from MP3 / WAV / M4A / OGG / FLAC / AMR audio
About this tool
Cutting the ten useful minutes out of a 90-minute recording, shortening a song to a 30-second ringtone, removing a long intro - all of it comes down to two time points. Plain seconds (45, 45.5) and clock formats (1:05, 1:02:03.5) are accepted; a blank start means 0, a blank end means the end of the file, and filling just one side works fine.
The output format may differ from the source: cut a ringtone and export M4A in the same step, or slice a recording into MP3 to save space. Audio encoding is extremely fast - usually a fraction of realtime - so a few minutes of material finishes in seconds.
The cutting is done by FFmpeg compiled to WebAssembly inside your browser: nothing is uploaded, which matters for private recordings.

Frequently asked questions
- How do I remove just the intro or the outro?
- Think in terms of the part you keep: fill both times to keep the middle, fill only the start time to keep everything from there to the end, or fill only the end time to keep the opening. Leaving the side you want to discard empty does the rest.
- Does cutting lose quality?
- Keeping the source format uses lossless stream copying - bit-identical output. Converting formats re-encodes at your chosen bitrate, a single generation of loss that is practically inaudible. FLAC/WAV output is mathematically lossless.
- Can I make phone ringtones with it?
- Yes - cut a segment under 30 seconds and export M4A. iPhone users can turn it into a ringtone via GarageBand; Android phones accept the file in the Ringtones folder. Note the iPhone ringtone ceiling of roughly 40 seconds, beyond which the system truncates.
