Trim audio (MP3 cutter)

How to use it

1. Add your file. Drop it on the box or choose it from your device.
2. Set it up. Play to the spot and press Start = current position, then the end. Or type the times, like 1:05.5.
3. Trim audio. Press Trim audio. Long or large files take a while on phones.
4. Download. Save the result.

What happens to your file

The audio is cut without re-encoding where the format allows, so quality is unchanged. Tick Exact cut for sample-exact cuts.

Clean trims

• Set the start a fraction of a second before the first word or note; cutting mid-sound causes an audible click.
• MP3 and M4A trims are re-encoded at the original bit rate. WAV and FLAC trims stay lossless.
• For ringtones, iPhone accepts up to 40 seconds in M4R format and Android plays any MP3. Try MP3 to M4R after trimming.
• Voice notes from WhatsApp arrive as Opus in an OGG file; trimming saves them as OGG so any player can open them.
• To lower the size of the trimmed clip, run it through Compress audio.
