How to convert WEBM to FLV
- Add your .WEBM file - drop it in the box above or click to browse.
- Convert it to .FLV in a few seconds.
- Download your new .FLV file.
What to expect
- Both streams are re-encoded from WEBM's codecs into FLV-supported ones (H.263/VP6/H.264 video, MP3/AAC audio), a lossy step.
- FLV is a frozen, Flash-era format; it still plays in VLC but is not widely supported outside legacy tooling.
- Only the video and audio carry over; WEBM-specific container metadata is not preserved.
Frequently asked questions
Will WEBM to FLV lose quality?
Yes, it is a re-encode. FLV carries H.263, VP6 or H.264 video with MP3 or AAC audio, none of which match WEBM's VP8/VP9/AV1 and Vorbis/Opus, so both streams are transcoded and some detail is lost.
Why would anyone convert WEBM to FLV?
FLV (Flash Video) was the standard for Flash Player and 2000s streaming sites. You would target it for legacy players, archives or tools that still require the Flash Video container.
Can FLV still be played now that Flash is gone?
Yes. FLV is plain linear video/audio data, and VLC opens it on any platform without Flash, which ended in December 2020. The file does not run code; it is not the exploit-prone SWF plug-in content.
Is FLV a sensible target format today?
Its specification was frozen after Flash's end of life, so it is a legacy container. It plays in VLC, but for anything modern MP4 is far more broadly compatible than FLV.
