10 best MP3 Editors you shouldn't miss

MP3 is the most common audio format these days. You'll get everywhere, including downloading music, playing podcasts, saving audiobooks, and so on. For this reason, arming yourself with a powerful MP3 editor is a must. With an MP3 song editor, you can trim, merge, compress, and even convert MP3 to other common audio formats. So, let's cut to the chase and list some ten best online and offline MP3 editors to consider.

Part 1. Top 5 MP3 editors online for free

1. Audio Trimmer

cool mp3 editor

As the name suggests, Audio Trimmer is a simple online program for trimming and converting sound files on the fly. With this MP3 track editor, you can cut audio by merely dragging the start and stop sliders or manually entering the playback duration. However, it doesn't stop there; Audio Trimmer allows you to make the audio track sound more professional by adding fade effects. And if you're satisfied editing MP3, you can export it to MP3 or M4R (iPhone ringtone). Just remember that the maximum supported file size is 100MB.


Simple to use.

Multiple file formats are supported.

Apply fade effects to audio.


Limited conversion size.

Too many adverts.

2. Online MP3 Cutter

lossless mp3 editor

Online MP3 Cutter is a cool MP3 editorwith a convenient drag-n-drop UI. You just need to load the MP3 file and drag the sliders to select the area to keep. Or, you can manually enter the start and stop time before applying fade effects. In addition to that, this simple-to-use MP3 editor exports MP3 to multiple formats, including MP3, M4R, FLAC, WAV, and M4A. And best of all, it allows you to extract sound from any video format. But just as expected, this free audio editor is ad-supported.

Multiple audio output presets.

Extract audio from video.


Ad-supported UI.

3. Clideo

software to edit mp3 files

Clideo is a simple, ad-free website with tens of file editing tools. With it, you can upload MP3 from local storage, Google Drive, or Dropbox before adjusting the playback duration by moving the markers on each end. Alternatively, you can insert the playback time in seconds before adding fade-in and fade-out effects to your MP3 track. And once you're done editing MP3, you can export to OPUS, FLAC, M4R, M4A, and other audio formats. But on the downside, the Clideo MP3 cutter has a slow rendering speed. Other than that, it's a high five.


Simple and modern UI.

Upload MP3 from cloud storage.

Multiple output presets.


Slow rendering speed.

No notable difference between the free and premium versions.

4. Kapwing MP3 Editor

Still not impressed by the options above? Try Kapwing MP3 Editor. Kapwing is an excellent online file editing tool that has mainly carved out a niche in the video editing department. But when it comes to editing audio, this MP3 song editor is also up there with the best. Users can cut, trim, and split MP3 on the multitrack timeline. In addition, you can adjust the audio volume, playback speed, reverse audio, and even duplicate the audio track. But unfortunately, Kapwing only supports MP3 exports. Even worse, the UI isn't for green hands.

5. Audio Tool Set Audio Cutter

Lastly, use Audio Tool Set Audio Editor to cut and convert MP3 online with lossless quality. You only need to upload MP3 and enter the start and stop durations on this platform. But an easier way is to drag trimming handles to select the audio section to keep. Apart from cutting audio, this rich toolset also comes with a bass booster, audio compressor, noise reducer, and many other audio editing functions. Sadly, this MP3 cutter doesn't offer any output audio presets. What's worse, the maximum supported file size is a mere 50MB.


Simple operation.

Fast rendering speed.

Multiple audio editing functions.


50MB upload limit.

No fade-in and fade-out effects.
