Need to trim an MP3 online to create a custom ringtone, extract a specific vocal hook for a remix, or remove a long silent intro from a podcast?

It is fast, completely free, and incredibly intuitive to use.
Top Uses for Our Online Audio Cutter
- Prep for AI MIDI Conversion: Running a full 4-minute track through a polyphonic AI to MIDI model can produce a messy result. By using our MP3 trimmer in-browser to crop out just the specific guitar solo or piano chord progression you want to transcribe, you ensure a much cleaner, faster, and more accurate MIDI conversion process.
- Visual Waveform Editing: Don't guess where the beat drops based on timestamps. Our tool generates a detailed, zoomable visual waveform, allowing you to accurately split a WAV file online precisely at the start of a drum transient or a vocal breath.
- Cut Song for Ringtone: Easily drag the left and right region handles to highlight the catchiest 15 seconds of your favorite song, crop the audio, and export it directly to your iPhone or Android as a custom ringtone or alarm sound.
- Podcast Editing: Quickly chop off the messy pre-roll banter or dead air at the beginning of a podcast recording before publishing it to Spotify or Apple Podcasts.
Lossless Export and Studio-Grade Processing
Many free online audio trimmers secretly re-compress your edited files into low-bitrate MP3s, ruining the high frequencies and destroying the sound quality of your music. Our tool is different: it exports your trimmed regions as uncompressed, high-fidelity WAV files. Whether you are cutting a lo-fi voice memo, a field recording, or a professionally mastered track, the output will sound exactly as crisp and punchy as the input.
100% Private - No Cloud Uploads or File Limits
Your privacy is our number one priority. Because our audio cutting engine utilizes modern Web Audio API and WebAssembly technology, the entire file processing happens locally on your device's CPU. Your proprietary audio files, voice recordings, and unreleased studio stems are *never* uploaded to the cloud or saved on our servers. This local processing architecture also means you can edit massive, gigabyte-sized audio files instantly with absolutely zero upload or download waiting times!
