Why trim audio
Cutting an audio file down to just the part you need is useful for ringtones, short clips for messages or social posts, pulling a highlight out of a longer recording, or removing dead air from the start or end of a track.
Good to know
The waveform gives you a visual way to find the right spot, and the precise time fields let you fine-tune the exact start and end down to a tenth of a second. Use the zoom controls to see fine detail in a long recording, and preview your selection before exporting to confirm it's exactly right.
MP3 Cutter FAQ
Is my audio uploaded anywhere?
No. Your file is decoded, trimmed, and exported entirely in your browser — nothing is sent to a server.
Can I trim files of any length?
There's no fixed limit in the tool itself — very long files are limited only by your device's available memory.
Does trimming reduce quality?
No re-encoding happens beyond what's needed to export. MP3 files are re-encoded at a high 128kbps bitrate; WAV export is fully lossless.
Will my exported file keep the original format?
MP3 and WAV inputs export in the same format. For M4A, AAC, OGG, and FLAC, this site can't re-encode those specific codecs in the browser, so the trimmed audio exports as WAV instead — clearly noted after export, never silently swapped.
Is it free?
Yes, trimming audio with this tool is free.
