Why convert FLV to WebM?
FLV was built for a web that no longer exists — no browser plays it today. Converting to WebM gives you a small, royalty-free file built for modern web pages and HTML5 video players.
FLV vs WebM at a glance
FLV is the video format that powered early YouTube and web video — Adobe Flash Player was discontinued in 2020, so FLV files no longer play in any current browser. WebM is the open web video format — smaller than MP4 at the same quality, royalty-free and supported by every modern browser.

FLV to WebM — frequently asked questions
Is this FLV 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.
