How to trim an audio file
- Add the audio. Drop an MP3, M4A, WAV, OGG or FLAC file, or a video whose sound you want.
- Mark the part to keep. Drag the yellow handles over the waveform or type the start and end. Play it: the player loops your selection.
- Add fades if you like. Half a second to two seconds sounds natural.
- Pick a format and save. Listen to the result on the page, then download it.
Reading the waveform
Tall parts are loud, thin parts are quiet, and a flat line is silence. Cutting in a quiet gap avoids a click; if the cut has to land in the middle of sound, a fade of a fraction of a second hides it. The faded-back parts outside the handles are what will be removed.
Which format to save
| Format | Use it for |
|---|---|
| M4A (AAC) | Ringtones, sharing, music libraries. Small and widely supported. |
| WAV | Editing further, broadcasting, anything that needs the exact sound. |
| OGG (Opus) | Voice clips for the web and Android, at the smallest size. |
Common problems
- A click at the start or end: add a fade of 0.5 seconds, or move the handle into a silent gap.
- "Couldn't decode the sound": the browser doesn't support this audio format. Convert it on a computer, or try Chrome.
- The result is bigger than the original: WAV is uncompressed. Choose M4A for a small file.
Frequently asked questions
Can I save the cut as MP3?
Only in browsers that can encode MP3, which most can't yet; the MP3 option turns on by itself where it's available. M4A is the closest choice and plays on phones, computers and in most apps. WAV is always available and has no further quality loss.
How do I make a ringtone?
Select about 30 seconds or less (phones limit how long a ringtone can be), add a short fade in and out, and save as M4A. On iPhone, a ringtone also has to be renamed to .m4r and added through Finder, iTunes or GarageBand. On Android, copy the M4A or WAV to the phone and pick it in sound settings.
How exact is the cut?
The sound is decoded completely, so you can cut on any sample. Type times to a hundredth of a second, or focus a handle and move it with the arrow keys: a tenth of a second per press, a second with Shift.
Is my audio uploaded?
No. It's decoded, cut and saved inside this browser tab.
Is there a length limit?
The whole file is decoded into memory to draw the waveform, so files up to about an hour work well. For longer recordings, use the audio converter or MP4 to MP3 with "Only save part", which read the file in pieces.
