About MP3 Cutter
MP3 Cutter is a free, browser-based audio editing tool built for simplicity and privacy. We believe trimming audio shouldn't require expensive software or uploading your files to a server.
Privacy First
Your files never leave your device. All processing happens locally in your browser.
Lightning Fast
Powered by the Web Audio API for instant, native-speed audio processing.
Free & Accessible
No sign-ups, no downloads, no limits. Works on any modern browser.
Our Mission
We started MP3 Cutter because we were frustrated with bloated audio editors that require installations and subscriptions. Our goal is simple: give everyone a fast, free, and private way to trim audio files.
How It Works
MP3 Cutter uses the Web Audio API built into modern browsers. When you upload a file, it stays entirely on your device — we never see or store it. You select the portion you want, and we encode the trimmed result right in your browser.
Open & Free
MP3 Cutter is free to use with no limitations. No watermarks, no file size restrictions, no account required. Just open the site and start cutting.
