About this tool

What is WEBM? WebM (Google) is an open video format designed for the web, using VP9/AV1 codecs and Opus audio. It’s ideal for website videos and browser screen recordings. Compatibility: it plays in all browsers, but not always on iPhones, in editing software, or on TVs.

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 WEBM and MP3?

Both use lossy compression. For compatibility: WEBM plays in all browsers, but not always on iPhones, in editing software, or on TVs; MP3 plays on all 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.
