Why convert WMV to MP3?

WMV is Microsoft’s Windows Media format. It shows up in old corporate video libraries and PowerPoint exports, and it stops dead the moment a file has to leave Windows.

The practical problem: macOS, iOS and Android need extra software, and usually just fail. Browsers cannot play WMV, so it can never be embedded on a page. Its compression is generations behind H.264, so files are bigger than they need to be.

MP3 solves that. Plays on every phone, car stereo, browser and podcast host in existence. Small enough to attach to an email or send in a chat. Accepted by every transcription and podcast service.

FAQ

WMV to MP3 questions

Is the WMV to MP3 converter free?

Yes. Convert and preview the result for free, then create a free account to download it. There is no per-file charge and no watermark on the MP3 itself beyond the free-plan badge.

Do I need to install any software?

No. The conversion runs on our servers and the whole flow happens in your browser, so it works the same on Windows, macOS, Linux, iPhone and Android. Nothing to install at either end. Where WMV plays: Windows; almost nothing else. Where the MP3 you get back plays: Every device made in the last 25 years.

Does converting WMV to MP3 reduce the quality?

The audio track is decoded from the WMV and written as MP3. MP3 is a lossy format, so there is a small re-encode, inaudible for speech at the default quality. The picture is discarded entirely, which is why the file gets so much smaller.

How large a file can I convert?

Anything under 1GB per upload, which is more footage in some formats than others. WMV: Moderate, but dated compression. MP3 coming back: Roughly a tenth of uncompressed audio. For anything bigger, trim or compress it first, both are free tools here.

Is my file kept private?

Your upload is processed and then held only as long as your project needs it. Nothing is published, indexed or shared unless you create a share link yourself.
