WMV vs WebM at a glance
WMV is Microsoft's proprietary video format for Windows Media Player — rarely supported outside Windows, and most modern devices and browsers can't play it at all. WebM is the open web video format — smaller than MP4 at the same quality, royalty-free and supported by every modern browser.

WMV to WebM — frequently asked questions
Is this WMV to WebM converter really free?
Yes — completely free, with no sign-up, no watermarks and no daily limits.
Will I lose quality converting to WebM?
WebM uses lossy compression, so the image is re-encoded at high quality (92%). For photos the difference is practically invisible; for text-heavy graphics or logos, a lossless format like PNG preserves sharp edges better.
Is the conversion private?
Video conversion runs on our servers with ffmpeg — your file is deleted immediately and never stored.
