Cut audio online for free with waveform and WAV download

Keep one continuous song section using two markers, precise time fields and audition playback. Optional fades help at cut edges. Export a new 16/24-bit or float WAV locally without overwriting the original.

PRACTICAL EXAMPLE · ILLUSTRATIVE, NOT A TEST RESULT

You need a specific song section as a separate file.

Try this: Set A and B on the waveform, audition the selection and export a new WAV. Short edge fades can reduce cut clicks.
How to interpret it: Check attacks and tails by ear. This tool keeps one continuous section; it does not normalize or join files.

A simple workflow for your recording

Clean up a voice recording if needed, keep the part you want, then create a smaller MP3 for sharing. Each tool is independent: download the result and choose it in the next tool. No automatic file transfer.

How it works

Choose browser-supported audio up to 80 MB
Drag A/B or enter start/end times
Check the selection and download WAV

Frequently asked questions

Can I cut MP3 online for free?

Yes, if your browser can decode the MP3. Audio Cutter exports the selection as WAV, not MP3. To create a smaller MP3 listening file, convert that new WAV using the WAV-to-MP3 tool.

Is my audio uploaded?

No. Decoding, cutting, auditioning and WAV export run in your browser, subject to memory limits.

Why suggest short fades?

Five-millisecond fades reduce clicks when cuts are not at zero crossings. Set both to 0 for hard cuts.

Can I join several files?

Not yet. This tool exports one continuous section. It does not normalize or restore information lost in MP3.
