Frequently asked questions
Is this audio trimmer really free?
Yes. Every trim and export is free, with no signup and no watermark. The tool runs entirely in your browser, so there are no server costs to pass on to you.
Does my audio get uploaded to a server?
No. Your file is decoded and processed by your own browser using the Web Audio API. You can go offline after loading the page and the trimmer still works — nothing is ever sent anywhere.
Which formats can I trim?
Your browser can decode MP3, WAV, M4A/AAC, OGG, FLAC and WebM audio. You can save the result as MP3 (128–320 kbps) or lossless WAV.
Will trimming reduce the audio quality?
Saving as WAV is bit-perfect for the part you keep — no re-compression. Saving as MP3 re-encodes once; at 192 kbps or above the difference is practically inaudible for most listeners.
Can I trim audio on my phone?
Yes. The waveform supports touch, and the export button stays reachable at the bottom of the screen. It works in Safari on iPhone and in Chrome or Firefox on Android.
How long can my file be?
Recordings up to about an hour work comfortably on a modern computer. The practical limit is your device memory, not an artificial cap.
