How to use it
- Drop an MP3, M4A, WAV, FLAC, OGG or video file.
- Drag the two handles on the waveform, or type start and end times.
- Set fade in and fade out, then play the selection.
- Pick MP3 or WAV and click Save selection.
Selecting the part you need
After the file opens you see its waveform: loud passages are tall, silence is flat, so it's easy to spot where speech starts or where the chorus kicks in. There are three ways to set the selection:
- Drag the handles at the start and end of the highlighted area, with a mouse or your finger.
- Type times in the Start and End boxes as minutes:seconds, for example
1:05.5, or plain seconds like65.5, then press Enter. - Use the keyboard: focus a handle and press the left or right arrow to move it by 0.1 second, or hold Shift to move by a full second.
Click Play selection to hear exactly what will be saved; a red line follows playback on the waveform.
Fade in and fade out
A hard cut in the middle of music can click or sound abrupt. The two sliders add a linear fade in at the start and fade out at the end, each up to 5 seconds in half-second steps.
| Use | Fade in | Fade out |
|---|---|---|
| Speech clip, quote | 0 s | 0–0.5 s |
| Music excerpt | 0.5 s | 2–3 s |
| Intro or outro music | 1–2 s | 3–5 s |
| Loop or sound effect | 0 s | 0 s |
The fades are applied inside your selection, so the length stays the same.
MP3 or WAV?
MP3 at 192 kbps is the right choice for sharing, phones and most apps; pick 320 kbps if you'll edit the clip again, 128 kbps for small files. WAV is lossless and uncompressed, best for audio editors and samplers, but about ten times larger.
The saved file keeps the original name with -trimmed added, so podcast.mp3 becomes podcast-trimmed.mp3. Any format your browser can decode works as input, including the audio track of MP4 or MOV videos.
Common uses
- Cut the silence or chatter at the start and end of a recording.
- Keep one answer from a long interview or one song from a live set.
- Make an intro or outro for a podcast or video.
- Create a short sound for an alarm or notification.
For a phone ringtone, the ringtone maker sets sensible defaults (30 seconds, fades) and has setup steps for iPhone and Android. To join several clips, use merge MP3.
Privacy and large files
The file is decoded and cut in your browser and never uploaded, so private recordings stay on your device. Long files (an hour or more, or over about 200 MB) need plenty of memory; they work best on a computer. Cutting a piece and saving it as MP3 re-encodes only that piece, so it's quick even for long originals.
Frequently asked questions
Can I cut a song without losing quality?
Save as WAV for a lossless result. Saving as MP3 re-encodes the selection; at 192–320 kbps the difference is inaudible for most listeners.
How do I cut several parts from one file?
Save the first selection, then move the handles to the next part and save again. The file stays loaded.
Does it work on a phone?
Yes. Drag the handles with your finger, or type the times. Very long files are better handled on a computer.
Can I trim the audio of a video?
Yes. Drop the video; the tool uses its soundtrack and saves an audio file. To trim the video itself, use the video trimmer.
Is my audio uploaded?
No. Decoding, cutting and encoding all happen on your device.
