MP3 Cutter
Cut MP3 files online for free — trim songs, podcasts and recordings to the exact part you need by setting a start and end time, add a smooth fade in and out, normalise the volume and save a new MP3. Ideal for ringtones, intros and clips. Runs privately in your browser.
100% private — your audio is converted on your device, never uploaded. Conversion happens on your device; nothing is uploaded.
Your browser decodes the audio and an open-source MP3 encoder (LAME, via lamejs) converts it on your device — nothing is uploaded. Works with MP4, MOV, M4A, WebM, MKV, WAV, OGG and more; very long files need plenty of memory, so trim if your browser struggles.
How to cut an MP3

How do I cut part of an MP3?
Drop the MP3 in, enter the start and end times (for example 0:45 and 1:15), and click Cut and save MP3.
How do I make a ringtone?
Cut a 20–30 second section, tick Fade in and out, and save. iPhones need the M4R format via GarageBand or iTunes; most Android phones accept MP3 directly.
Can I cut WAV, M4A or video files too?
Yes — any audio or video file your browser can play works, and the result is saved as MP3.
Which quality should I choose?
192 kbps sounds excellent for music and keeps files small; 320 kbps is the highest MP3 quality. For podcasts and speech, 96–128 kbps in mono is plenty.
Can I convert just part of the file?
Yes — set a start and end time (minutes:seconds) before converting. Fade in and out smooths the cut edges.
Is there a file size limit?
There's no upload limit because nothing is uploaded, but the whole file is decoded in your browser's memory. Files up to a few hundred MB work well on most computers; for very long recordings, convert in parts.
Is my file uploaded?
No. Decoding and MP3 encoding both happen on your device.
