About this tool
Make a ringtone, cut the silence off a recording, or keep the one useful minute of an hour-long file. Enter the start and end in seconds and the section is exported as an MP3 at the bitrate you choose. Any common audio file works, and video files are accepted too, in which case only the audio is kept.
Everything happens inside your browser. Your file is never uploaded to a server: the conversion runs on your own device using WebAssembly, and the result is downloaded straight from memory. Close the tab and nothing is left behind.
How to use it
- Drop your MP3 file into the box above, or click to browse. Nothing is uploaded.
- Adjust the options if you want; the defaults suit most files.
- Click the button and wait a moment.
- Download the result.
Frequently asked questions
Can I trim without re-encoding?
The trimmed section is encoded to MP3 at high quality; for a lossless cut, export to WAV with the MP3 to WAV tool first and trim that.
How do I make an iPhone ringtone?
Trim to under 40 seconds, convert the MP3 to M4A, and rename the extension to .m4r.
Is this really free?
Yes. The site is supported by ads, and there are no limits on how many files you convert.
Are my files uploaded anywhere?
No. The converter runs entirely in your browser. Files stay on your device, which also makes it faster than upload-based converters for anything larger than a few megabytes.
Is there a file size limit?
The only limit is your device's memory. Images and audio of any normal size are fine; for video, files under about 500 MB work well on most laptops and phones.
Which browsers are supported?
Current versions of Chrome, Edge, Firefox, and Safari on desktop and mobile. Very old browsers without WebAssembly support will not work.
