About Audio cutter & ringtone maker

Audio cutter decodes your file, shows its waveform and saves just the part you select as a new audio file. The result is re-encoded from the decoded samples: MP3 at 192 kbps by default (96 to 320), M4A with AAC at 192 kbps, OGG with Opus at 128 kbps, or uncompressed WAV when you want no further loss. Fades are applied sample by sample, so even a short one lets the clip start and end without a click, and the volume control applies a clean gain of up to ±12 dB. Title and artist tags are carried over; ringtones get the file name as their title.

The iPhone ringtone preset writes an .m4r file with AAC at 256 kbps and limits the selection to 40 seconds, the longest an iPhone ringtone can be; the result screen explains how to install it with Finder, iTunes or GarageBand. The Android preset saves an MP3 that you copy to the phone's Ringtones folder.

Typical uses: a ringtone or alarm from the chorus of a song, a short sound for a video or presentation, a single answer out of a long interview, or trimming silence from a voice memo. Because the clip is re-encoded, choose WAV or a high bitrate if you plan to edit it further. The tool cuts one continuous part per file and doesn't mix tracks, remove vocals or reduce noise; audio from DRM-protected purchases can't be opened.

Privacy

Your browser decodes the audio with the Web Audio API, falling back to WebCodecs through mediabunny or to ffmpeg.wasm in a Web Worker for unusual formats, and the clip is encoded in the same tab. The file never leaves your device. The 31 MB ffmpeg core is fetched from the jsDelivr CDN only for formats that need it, then cached, and carries none of your audio.

Audio cutter & ringtone maker: frequently asked questions

How do I make an iPhone ringtone from an MP3?
Open the MP3, select up to 40 seconds of the song and choose the iPhone ringtone preset; a short fade out makes the loop sound natural. Press Make ringtone to download an .m4r file. Then connect the iPhone to a Mac or PC and drag the file onto it in Finder or iTunes, or open it on the phone with GarageBand and share it as a ringtone.
Can I cut an MP3 without losing quality?
The cut part is decoded and encoded again, so an MP3 saved as MP3 goes through a second round of compression. At 192 kbps or more that is very hard to hear, and at 320 kbps it is practically inaudible. If the clip will be edited further or must stay pristine, save it as WAV, which stores the decoded audio without any additional compression.
Can I cut the audio from a video?
Yes. Drop an MP4, MOV, WebM or other video; the tool reads its soundtrack, shows the waveform and ignores the picture. Select the part you want and save it as MP3, M4A, WAV or OGG. That is a quick way to keep one song from a concert clip or a quote from a recorded talk. To convert the entire soundtrack instead, an audio converter is faster.
How precise can I cut?
You can type start and end times with millisecond precision, and the arrow keys move the playhead in 0.1-second steps, or one second with Shift. Press I or O to set the start or end at the playhead while listening. Because the audio is decoded to individual samples, the cut lands exactly where you put it, unlike tools that copy compressed MP3 frames of about 26 milliseconds.
How do I add a fade in or fade out?
Use the Fade in and Fade out sliders under Fades & volume. Each can be up to 10 seconds, or half the clip's length if that is shorter, in 0.1-second steps. The fades are calculated on the samples themselves, so they are smooth, and you can hear them immediately with Play selection. A fade out of one or two seconds is ideal for ringtones and alarms.
