Free Online MP3 Editor

This page is also available in other languages: Deutsch, 한국어, 日本語, Español, Português (Brasil), Français

This editor runs right in your browser, nothing to install. Load an MP3 or WAV and the track turns into a waveform you edit by eye: select a region to trim it, move sections to rearrange them, or pick an effect from the panel, reverb, bass boost, 8D/spatial audio, slowed + reverb, and speed or tempo changes. Nothing to install, no account to make.

To use it, open the editor and upload a file from your device. Wait a moment while the track is analyzed and the waveform appears. Make your cuts and effect tweaks, play back to check them, then export the finished MP3.

Because you're editing visually, zoom in on the waveform before you cut. At a close zoom you can see individual beats and the gaps between words, so a cut lands exactly where you want instead of a fraction of a second off. This matters most when you're trimming silence off the start and end, or cutting a clip down to just the part you need.

It's also good for quick effect versions of a song: a slowed + reverb edit, a bass-boosted mix, or an 8D pan that swings the sound around in headphones. Apply the effect, preview it, and download.

And yes, it's free with no catch. No signup, no download, no watermark on your audio. You upload, edit, and export your MP3 right in the browser.
