Cut and Trim MP3 Files Online

Atlasaro Audio Cutter can also be used as a convenient MP3 cutter. Select an MP3 file, choose where the trimmed audio should start and end, and create a new MP3 file from the selected section.

This can be useful when you want to remove the beginning or end of a song, shorten a long recording, create an audio clip, or keep only a specific part of an MP3 file.

Which Audio Formats Are Supported?

The audio cutter accepts several common audio file formats, including MP3, WAV, OGG, M4A, AAC, FLAC, OPUS, and WEBM.

Actual compatibility can depend on the codec contained in the file and the browser being used. The browser must be able to load the selected audio for preview, while the processing stage uses FFmpeg WebAssembly to create the trimmed MP3.

Does the Audio Cutter Upload My File?

No. Atlasaro Audio Cutter is designed for local browser-based audio processing. Your selected audio file does not need to be uploaded to an Atlasaro server for the trimming operation.

This approach allows you to cut an audio file directly on your device without sending the original recording to a remote processing server.

Is the Audio Cutter Free?

Yes. Atlasaro Audio Cutter is a free online audio cutter designed for quick and convenient audio trimming.

You do not need to install a desktop audio editor just to cut a short audio clip. Open the tool, select your file, choose the section you want to keep, and download the finished MP3.

Why Use an Online Audio Cutter?

An online audio cutter can be useful when you need to make a quick edit without installing additional software. Instead of opening a full-featured audio editor, you can use your browser to select the part of the recording you need.

Atlasaro Audio Cutter can be useful for trimming music, shortening voice recordings, removing unwanted sections, creating short audio clips, and preparing audio files for sharing.
