About FLV to MP4
FLV is a leftover from the Flash era, and most modern devices, browsers, and editors no longer play it well. If you have old FLV recordings or downloads sitting unused, converting them to MP4 brings them back to life. This tool makes those files watchable again on today's hardware.
Upload your .flv file and the converter repackages the video into an MP4 container, typically with H.264 video and AAC audio for broad compatibility. It runs entirely in your browser, is free to use, and never adds a watermark or asks you to sign up. Your file is handled only for the conversion and isn't kept afterward, so old footage stays private.

FAQ
Can I still play FLV files anywhere?
Rarely. Flash support is gone from browsers, so FLV needs niche players. MP4 solves that by playing almost everywhere.
Will converting improve the video?
It won't add detail that isn't there, but it makes the same footage compatible and easy to play and edit today.
Is the audio preserved?
Yes, any audio in the FLV is re-encoded and included in the MP4.
Can I use FLV to MP4 on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
