About this tool

What is MP3? MPEG-1 Audio Layer III: one of the most widely supported audio formats, with compression that reduces music files to about one-tenth of their original size. It's ideal for music, podcasts, and audio you want to play anywhere. Compatibility: plays on phones, in cars, on speakers, and in software.

Why convert to WAV? Uncompressed audio with maximum quality and large file sizes (about 10 MB per minute). It's the best choice for professional audio editing and recordings you'll edit later—widely supported, but large to send.

Frequently asked questions

What's the difference between MP3 and WAV?

MP3 uses lossy compression, while WAV preserves audio quality with lossless encoding. Compatibility: MP3 plays on all phones, in cars, on speakers, and in programs. WAV works everywhere, but its files are large and harder to share.

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.
