How do I cut MP3 online?

Drop your MP3 into the AuTrans cutter, drag the start and end handles to the section you want, and click Download. The trimmed file lands in your downloads folder in seconds, no install, no signup for files under 100 MB.

Is there a free audio cutter without watermark?

Yes. AuTrans's cutter is free for files under 100 MB and never adds a watermark or audio sting. Files above 100 MB or batch jobs upgrade to Pro.

How do I trim audio without losing quality?

Lossless formats (WAV, FLAC) trim with zero quality loss. Lossy formats (MP3, AAC, OGG) re-encode at high VBR to keep the cut clean. For an exact-cut without any re-encode, output to WAV or FLAC.

Can I cut audio on iPhone or Android?

Yes. AuTrans runs in any browser. On Android, install AuTrans as a PWA and the cutter works offline. iPhone Safari works in-browser; sub-60 second clips return almost instantly.

Is uploading audio safe?

Audio you upload is private and is never used for training. We delete it on request, per our Privacy Policy and NDPA-compliant retention rules.

How long can the audio file be?

Up to 2 hours per file on free; Pro covers files up to 4 hours. The cutter handles long files efficiently, only the audio window you mark is processed.
