Frequently asked questions
Is the wav to mp3 converter free?
This is a Pro tool. With a free account you get one run a day to try it; Pro and Lifetime plans include unlimited use.
Are my files uploaded to a server?
No. The conversion runs entirely in your browser, so your files never leave your device. We only count how many files you convert — never their names or contents.
What is the maximum file size?
Up to 25 MB per file without an account, 50 MB with a free account, and 1 GB on Pro. Very large files also depend on your device’s memory.
Can I convert multiple WAV files at once?
Yes. Select several WAV files at once — up to 5 on the free plan or 50 on Pro — and download all results in a single ZIP.
Does it work on Mac, Windows, iPhone and Android?
Yes. It works in any modern browser — Chrome, Edge, Firefox and Safari — on desktop and mobile, with nothing to install.
