Audio Trimmer

Question 1

What audio formats can I trim?

Answer

Any format your browser can decode: MP3, WAV, OGG, AAC, FLAC, and M4A. Output is always WAV.

Question 2

Why is the output always WAV?

Answer

WAV (PCM) encoding can be done entirely in JavaScript without external libraries. For other output formats, use the Audio Converter tool.

Question 3

Is there a file size limit?

Answer

No server-side limit since files never leave your browser. Very long audio (1 hour+) may require significant memory.

Question 4

Is this tool free?

Answer

Yes, completely free. No subscription, no credit card, no hidden fees.

Question 5

Do I need to create an account?

Answer

No. There is no login, no sign-up, and no account required. Just open the page and use it.

Question 6

Is my data private?

Answer

Yes. Everything runs entirely in your browser. Your audio files are never sent to any server.

Question 7

Does it work offline?

Answer

Yes. The Audio Trimmer uses only built-in browser APIs and works fully offline.
