Trim audio and cut your own ringtones
Cut any section out of a song, podcast or voice recording. Set the start and end point and download just that piece.
How it works
Choose your audio file
The track is loaded locally in this tab.
Set the boundaries
Move the start and end sliders to frame the section you want.
Choose accuracy
Exact timing re-encodes; a fast cut leaves the audio untouched.
The track is opened, not sent
Editing audio normally means uploading the file and hoping the service is trustworthy. Here your browser opens the track from your disk, works on it in place, and saves the result back. The audio never crosses the network.
- Opened from your disk by your browser — not sent anywhere first.
- Held in the tab while the tool works, then dropped.
- Saved to your device by your browser, not by a link to a server.
- Closing the tab clears the working copy completely.
- No account, so nothing is ever attached to an identity.
- No tracking of what you worked on or what was inside the file.
There is no queue, no render farm and no waiting room. The track is worked on in front of you and released the moment the tab closes. The how it works page covers what actually happens inside the tab, and our DevTools guide shows how to confirm 0 bytes are uploaded.
What people use it for
Making a ringtone
Cut roughly thirty seconds out of a song, save it, and set it as your ringtone in your phone settings.
Sending a voice note that is too long
A ten-minute recording is a lot to ask someone to play. Trim it to the useful minute and it actually gets heard.
Fitting an episode inside a feed limit
Podcast hosts set a maximum size. Checking the result here saves a failed upload later.
Keeping a copy that will still open in ten years
A widely supported format is a safer long-term bet than a container only one app understands.

When something goes wrong
Corrupt files, and formats outside the list above, stop with a plain message rather than a spinner that never finishes. If a track plays in your music app it will normally open here.
The audio container is not one the browser can read. Convert it to MP3 or WAV first, then run it through again.
Why not an upload site
An upload-based audio editor sends your recording to a server and sends the result back. Removing that round trip removes the waiting, the caps and the copy of your file.

Questions
Can I use this to make a ringtone?
Yes. Trim the section you want to roughly 30 seconds, then download it and set it as your ringtone using your phone's settings.
What is the difference between the two modes?
Frame-accurate mode cuts at exactly the moment you specify, which requires re-encoding the audio. Fast cut mode copies the original data without touching it, so it is instant and lossless, but the cut points may shift very slightly.
Does trimming a lossy file reduce its quality?
Only if you re-encode it. A fast cut copies the original audio data, so no additional quality is lost. Re-encoding a lossy file does introduce a small amount of further loss.
Is there a file size limit?
No fixed limit is imposed by the tool. The practical ceiling is how much memory your device has free, because the whole job runs inside this browser tab.
Does it work without an internet connection?
Yes, once the page has loaded. Nothing is fetched while you work, so a dropped connection does not interrupt a run.
Do I need an account or an email address?
No. There is nothing to sign up for, and nothing is ever attached to an identity because no file leaves your device.
