Does trimming reduce the audio quality?

Not by itself. The cut is sample-accurate and the audio is not re-encoded, so a WAV export is the original quality. Choosing MP3 re-encodes, which is the trade you make for a smaller file.

How long a recording can I trim here?

Up to 200 MB or 60 minutes. The whole file is decoded in this tab, so a very long recording will use a noticeable amount of memory while you work on it.

Can I cut a piece out of the middle and keep both ends?

This page keeps the selection and drops the rest. To keep both ends, trim each piece separately and then put them back together on the join-audio page.

Is this the same thing as an MP3 cutter?

Yes — the words differ, the job does not. There is a page at the mp3-cutter address that opens this same tool with MP3 already chosen as the output.

Cut audio to the part you want

Pick out a chorus, a quote, or a ringtone. Load a file, drag the handles across the waveform or type exact start and end times, listen to just the selection to be sure, and export it. As a sound trimmer it is instant and lossless — audio cutting here does not re-encode anything unless you ask for MP3 — and nothing is uploaded.

How to trim audio online

Drop an MP3, WAV, OGG or WebM onto the page. It is decoded on your device.
Drag the two handles across the waveform, or type an exact start and end time.
Play just the selection to check the cut lands where you meant it to.
Export as WAV to keep it lossless, or as MP3 for a smaller file.
