Convert FLV to MP4 Online
Rescue your old Flash videos. Since Flash Player's death, FLV files don't play in browsers. Convert them to MP4 to watch them again.
Why Convert FLV to MP4?
Adobe Flash Player was officially discontinued and removed from all major web browsers in December 2020. Since then, FLV (Flash Video) files can no longer play in Chrome, Safari, Firefox, or Edge, making millions of archived web videos from the 2005-2015 era completely inaccessible without conversion.
Converting FLV to MP4 (H.264 with AAC audio) is the only practical way to view, edit, share, or upload these old web videos to modern platforms like YouTube, Facebook, Instagram, TikTok, or simply play them on your phone, tablet, or smart TV.

Frequently Asked Questions
What opens FLV files now?
Very few default players open FLV. VLC Media Player can, but for sharing or mobile viewing, you must convert to MP4.
Is quality lost during conversion?
FLV quality is usually low resolution (web quality from 2005-2015). We maintain the original bitstream quality as much as possible.
Can I edit FLV in Premiere Pro?
Modern video editors often drop support for FLV. Converting to MP4 makes the footage editable in Premiere, Final Cut, and DaVinci Resolve.
Is it free?
Yes, our FLV to MP4 converter is completely free to use online with no registration required, no watermarks, and no daily conversion limits.
