About this tool

What is M4A? MPEG-4 Audio (AAC) is Apple's standard audio format (used by iTunes and the iPhone Voice Memos app). It offers better quality than MP3 at the same file size. It's a good choice for Apple Music and iPhone recordings. Compatibility: it works great with Apple products, but MP3 is a better choice for some older devices and Windows programs.

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 M4A and MP3?

Both use lossy compression. Compatibility: M4A works great with Apple products, but MP3 is a better choice for some older devices and Windows programs. MP3 plays on all phones, in cars, on speakers, and in programs.

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.
