Frequently Asked Questions

AudioNeo is a collection of free browser-based audio tools — convert, trim, compress, merge, adjust speed and volume, all right in your browser. No uploads, no installs, no signups, 100% private.

Is AudioNeo really free?+

Yes, completely free. No hidden fees, no watermarks, no paywalls. We don't even run ads on the tool pages.

The tools run entirely in your browser using WebAssembly, which means we have zero server costs for processing — and we pass that savings straight to you.

Do my audio files get uploaded to your server?+

No. All processing happens locally in your browser using FFmpeg WebAssembly.

Your files never leave your device, never touch our servers, and nobody else can access them. It's as private as editing a file on your own computer.

What audio formats are supported?+

All major formats are supported, including MP3, WAV, OGG, AAC, M4A, FLAC, OPUS, and WMA.

For video files, we support MP4, MKV, MOV, AVI, and WebM — you can extract audio directly from any of them.

Is there a file size limit?+

There's no hard limit imposed by us. The only constraint is your device's available RAM.

Most files under 500 MB work smoothly on modern devices. Larger files may take longer to process but will still work if your browser has enough memory.

How does AudioNeo compare to other online audio tools?+

Most online audio tools upload your files to a server, process them there, and send you the result. That takes time, uses bandwidth, and raises privacy concerns.

AudioNeo does everything in your browser. No uploads, no waiting in queues, no privacy risk. It's usually faster — and always private.

Can I use AudioNeo on my phone?+

Yes. AudioNeo works on any modern browser — Chrome, Safari, Firefox, Edge — on both desktop and mobile.

The interface adapts to your screen size, and all tools work on mobile devices just like they do on desktop.

Do I need to create an account?+

No account needed. No email, no registration, no login. Just open the tool and start using it.

We don't track you, we don't store your files, and we don't ask for personal information.
