About this tool

What is AAC? Advanced Audio Coding: MP3's successor, used in MP4 videos, YouTube, and iPhone. It's ideal for video audio and streaming. Compatibility: widely supported, but standalone .aac files may not open in older players.

Why convert to MP3? MP3 is one of the most widely compatible audio formats, and its compression can reduce a music file to about 1/10 of its original size. It's a great choice for music, podcasts, and audio you want to play anywhere—on phones, cars, speakers, and software.

Frequently asked questions

What's the difference between AAC and MP3?

Both use lossy compression. Compatibility: AAC is widely supported, but standalone .aac files may not open in older players; MP3 plays on phones, in cars, on speakers, and in software.

Does it work in all browsers?

It works in current versions of Chrome, Edge, Firefox, and Safari that support WebCodecs. Processing uses your device’s video acceleration, so it’s usually faster than uploading the file to a website.

Is there a file size or video length limit?

We don’t set a limit. Very large files (several GB) depend on your device’s memory; on phones, we recommend videos that are a few minutes long or less.

Are my files uploaded to a server?

No. This tool runs entirely in your browser: your file is read and processed on your device, and not a single byte is sent over the internet. You can even disconnect from the internet after the page loads.

Is it really free? Is there a daily limit?

It's free with no daily limits. Processing happens on your device, so there's no per-use cost and no need to limit you.

Does it work on phones?

Yes. The site works in any modern browser on Android, iPhone, Windows, Mac, and Linux—no installation needed.
