The format
What is an FLV file?
Flash Video
FLV is the Flash Video format that powered YouTube and most web video until the early 2010s. Adobe discontinued Flash in 2020 and browsers no longer play FLV, so old downloads and recordings in this format need converting to stay watchable.
What opens FLV files
VLC, mpv, and some desktop media players. Browsers, phones, and QuickTime can't play it.
FAQ
Questions, answered
Is the FLV converter free?
Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.
Are my files uploaded anywhere?
No. Everything runs inside your browser with FFmpeg compiled to WebAssembly, so your files never leave your device. Once the page has loaded, it even works offline.
Does it work on iPhone, Android, Mac, and Windows?
Yes, in any current browser on a computer or phone. FFmpeg runs on your processor without hardware acceleration, so long videos are much faster on a computer.
What can I convert FLV to?
MP4, MOV, WebM, MKV, MP3, WAV, GIF, and AVI. Pick the format after adding your file.
