MP3 Editor Free Online

Load an MP3, see it drawn as a waveform, and start editing. It handles common files like MP3 and WAV, and there's nothing to download and no account to make.

Drag your file onto the page. When the waveform loads, select a part and trim it, drag sections to reorder them, or open the effects panel to add reverb, bass boost, 8D/spatial audio, a slowed + reverb feel, or a speed and tempo change. Play it back as you work, then export the result.

Most people land here to make a quick effect version of a song: a slowed + reverb edit for a video, a bass-boosted copy for the car, or an 8D mix for headphones. You can do any of those in one pass and save the file.

It also works for plain trimming, like cutting silence off the front, shortening a long intro, or grabbing one section as a clip.

Worth knowing: editing inside the tool is non-destructive, so the original loads untouched and you change what you export. Once you export and overwrite the source MP3, though, that cut audio is gone, so keep your original file.

People usually ask if it's free with no catch. It is. It runs in the browser and needs no signup or install.
