Cut a song to 30 seconds and save it as an M4R ringtone, with no upload and no app
Processed in your browser. Nothing is uploaded. Updated on 24 Oct 2026.An iPhone ringtone is an M4R file: AAC sound in an MP4 container, at most 30 seconds long according to Apple. Drop any song here, pick the 30 seconds you want on the waveform, and the page encodes the M4R inside your browser with a short fade at each end. Below the button are the steps for setting it on the phone with GarageBand, the route Apple documents.
Choose the MP3 or other song file; Format is already M4R (iPhone) and Ringtone mode is on.
Mark up to 30 seconds with the handles; if it runs longer, press Keep the first 30 seconds.
Set Fade in and Fade out to None, 1 s, 2 s or 3 s.
Press Make the ringtone and Download the .m4r, then follow the GarageBand steps shown on the page.
Mark the parts of a recording worth keeping, press the button, and each one arrives as its own file. The file is read by this page on your own device; no copy is sent anywhere, no account is asked for, and nothing is stamped on the sound.
WAV is always available: the decoded samples written out untouched, exact but large, about 10 MB a minute in stereo. M4A is AAC in an MP4 container, encoded by the browser's own WebCodecs encoder at 256 kbps, and about a fifth of that size. Chrome, Edge and Safari 16.4 or later have that encoder; where a browser lacks it, the page says so before the button rather than failing after it. MP3 comes out only when an MP3 went in, because no browser can encode MP3 and the free encoders carry a copyleft licence this site will not ship. The original frames are copied instead, so the sound is untouched, but each cut lands on a 26-millisecond frame edge and cannot fade.
Ringtone mode keeps one clip, fades it in over a second and out over two, and saves it for a phone. For an iPhone it writes M4R, which is an M4A under the name iPhone ringtones use, and holds it to 30 seconds, Apple's published limit. Apple documents one way to set a custom ringtone: import the file into GarageBand on the iPhone, then Share, Ringtone and "Use sound as". Dragging an M4R onto the phone in Finder or iTunes also works for many people, but Apple does not describe it. Android plays MP3, M4A and WAV ringtones with no length limit.

Drop the MP3 on this page and the browser decodes it on your own device, with no request to any server. Drag the two handles across the part you want and press the cut button. The clip is written in the page and saved straight to your downloads folder, so no copy of the recording ever exists elsewhere.
Audio kaise cut kare: add the file to this page, drag the two handles to the part you want, and press the cut button. No app, no account and no upload is involved, because the browser does the work on your own phone or laptop. The clip is saved as a WAV file.
A cut that lands in the middle of a waveform leaves a sudden step in the signal, and a step is heard as a click. Each clip therefore fades in and out over five milliseconds, which is too short to notice but long enough to remove the step. Raise the fade if a click survives.
Apple documents one route: save the file to the Files app, import it into GarageBand on the iPhone, then tap Share, Ringtone, Export and "Use sound as". GarageBand also takes the M4A or MP3. Dragging the M4R onto the phone in Finder or iTunes works for many people, but Apple's support pages do not describe that route.
