Frequently Asked Questions

Can I still open my old FLV files?

Most media players dropped Flash support years ago. Converting FLV to MP4 makes those archived videos playable again, without installing anything.

Is it safe to convert FLV videos online?

Yes. Unlike traditional online converters, this tool never uploads your files. The conversion runs entirely inside your browser using WebAssembly, so FLV videos never leave your device — you can even disconnect from the internet after the page loads and it still works.

Is this converter really free?

Yes — completely free, with no sign-up, no watermarks, and no file-per-day limits. Because conversion happens on your own device, there are no server costs to pass on to you.

  • Limit free use or add watermarks
  • Track you or show spammy ads
