About FLV
FLV
FLV (Flash Video) is a container format used to deliver video over the web using Adobe Flash Player. Although Flash has been discontinued, FLV files remain common in older video archives. FLV typically wraps Sorenson Spark or VP6 video and MP3 or AAC audio.

Frequently Asked Questions
What is an FLV file?▼
FLV (Flash Video) was the dominant web video format in the Flash era — used across YouTube and streaming sites before HTML5. It is now deprecated and barely supported by modern browsers.
Why convert FLV to MP4?▼
Flash was discontinued in 2020, so FLV files no longer play in browsers. Converting them to MP4 rescues legacy videos for modern playback.
Is FLV still used?▼
Almost never for new content, but large archives of old Flash videos remain. Converting is the best way to make them usable today.
Does converting FLV lose quality?▼
A small amount, since FLV typically used old codecs. Converting to modern H.264 MP4 usually keeps the visible quality while making the file far more compatible.
Are my old videos uploaded when converting?▼
No — conversion runs locally in your browser.
