Frequently asked questions

Which audio formats can I trim?

Anything your browser can decode — MP3, WAV, M4A/AAC, OGG and more. The export is WAV, which plays everywhere and keeps full quality.

How do I cut out just the part I want?

Load the file, set the start and end points with the sliders, check the selection length, preview it, and export — you get exactly that section as a WAV.

Does trimming reduce audio quality?

The cut is exported as lossless WAV, so the kept section is at full decoded quality — there's no extra lossy re-encode.

Is my audio uploaded?

No — decoding, trimming and encoding all happen in your browser with the Web Audio API. Recordings stay on your device.

Is Audio Trimmer free to use?

Yes. Audio Trimmer is completely free on GenRise, with no limits, watermarks, or hidden paywalls.

Do I need to create an account or sign up?

No. Every GenRise tool works instantly in your browser — no account, email, or sign-up required.

Is my file uploaded to a server?

No. Audio Trimmer runs entirely on-device using your browser, so your files are never uploaded or stored anywhere. All processing happens locally.

How does Audio Trimmer work?

Audio Trimmer uses your browser's built-in capabilities — Canvas, WebAssembly, and File APIs — to process files locally. Trim an audio file to the exact section you need and export it. Simply open the tool, select your file, and the result is generated instantly on your device.

Is Audio Trimmer safe and private?

Yes. Since Audio Trimmer processes everything in your browser, your files never leave your device. There is no server-side storage, no tracking of file contents, and no data collection.

Can I use Audio Trimmer on mobile?

Yes. Audio Trimmer works on any modern browser, including mobile devices. It is fully responsive and optimized for both desktop and mobile use.
