Why convert FLV to MP4 with our tool?

Just drop the clip, wait a few seconds, and download a streamlined MP4 that’s easier to share, edit, and archive.
Upload your FLV above and our tool converts it to MP4 automatically. No tech skills required.
What makes MP4 better than FLV — and how do we optimise it?
MP4 taps efficient codecs (H.264/H.265) for crystal-clear quality at a lower bitrate. Our converter auto-selects settings that preserve detail while trimming megabytes, so even lengthy HD videos stay lightweight. The result: faster uploads, smoother streaming, and full compatibility across browsers and social platforms.
Which players can still open FLV files?
Few modern apps open FLV natively. VLC Media Player does, and you can still use legacy Flash-based players, but converting to MP4 is the safer bet.
VLC Media Player: Free, open-source, and available on every major platform.
Adobe Flash Player (legacy): Runs older FLV content in browsers that still support it.
Dedicated FLV Player: Lightweight desktop apps exist, but compatibility varies.
