Quick answer
To cut a WAV file without quality loss, load it into the WAV Cutter, select the region, choose WAV as the output format and export. The audio is copied sample-for-sample into a new 16-bit PCM WAV file. Choose MP3 instead if you need a smaller file.
How to use the WAV Cutter
- Open a WAV file16/24/32-bit PCM and float WAV files are supported.
- Select the regionDrag on the waveform or enter exact times.
- Pick WAV outputSelect WAV for lossless output, or MP3 to shrink it ~10×.
- ExportDownload the cut file instantly.
Lossless vs. MP3 output
WAV stores uncompressed PCM — about 10 MB per stereo minute at 44.1 kHz. MP3 at 192 kbps is about 1.4 MB per minute and is transparent for most listening. Keep WAV for further editing, mastering or sample libraries; use MP3 for sharing.
Sample-rate handling
WAV output keeps the original sample rate (e.g. 48 kHz or 96 kHz). MP3 output is automatically resampled to 44.1 or 48 kHz because MP3 does not support higher rates.

Frequently asked questions
Is 24-bit preserved?
The editor works internally in 32-bit float; exported WAV files are 16-bit PCM, which is the universal playback standard.
Is MP3 Cutter really free?
Yes. Every feature — cutting, fading, volume, speed and MP3/WAV export — is free with no sign-up, no watermark and no daily limit. The site is supported by unobtrusive ads.
Are my files uploaded to a server?
No. Your audio is decoded and processed entirely inside your browser using the Web Audio API and an MP3 encoder that runs locally. The file never leaves your device, so it works even for private recordings.
Does it work on iPhone, Android and Chromebook?
Yes. MP3 Cutter runs in any modern browser — Safari on iPhone/iPad, Chrome on Android, Chrome OS, Windows, macOS and Linux. No app install is required.
