Free MP3 Cutter
Use Free MP3 Cutter, review the result, and keep the original until the output is checked.
How to use Free MP3 Cutter
- Select the track; its waveform is drawn so you can see where the cut will land.
- Drag the two handles on the waveform, or type Start Time (seconds) and End Time (seconds) to the tenth of a second.
- Press Preview Selection to hear the range before committing.
- Set bitrate and other options as you like, Convert All, then Download the <name>_cut.mp3 file.
What Free MP3 Cutter actually does to your file
The cut is made by decoding and re-encoding, which means sample-accurate edges but one generation of lossy encoding on top of the original - leave End Time at 0 to run to the end of the file. Silence padding is not added, so the output is exactly the length you selected. Leave some overlap if you plan to join the pieces again later.
Free MP3 Cutter FAQ
What does Free MP3 Cutter do?
Trim a supported audio file in your browser. Choose the start and end points, preview the clip, and download the result.
Which files work with Free MP3 Cutter?
This category commonly supports MP3, WAV, AAC, OGG, and M4A. Use the accepted file types shown in the uploader, because support varies by browser and by the engine behind each tool.
Does trimming re-encode the file?
Trimming to exact frames needs a re-encode, which costs quality and time. A fast cut on the nearest keyframe keeps quality but can be off by up to a second, so check the duration of the download.
Will my original file be changed?
No. The work is done on a copy in this tab by your browser's audio decoder and a WebAssembly build of ffmpeg, and the result arrives as a separate download, so your original is still there if you need it.
How is my file processed?
It is not uploaded. The processing is done locally by your browser's audio decoder and a WebAssembly build of ffmpeg, so the practical ceiling is your device's memory and the limit shown beside the uploader - no queue, no account, no copy on a server.
Are my files uploaded to your servers?
Many EditTools pages process files in your browser, so data never leaves your device. When server processing is required, files are handled over encrypted connections and removed according to our privacy policy.
