How to convert FLV to MP4
Flash is gone, so old FLV videos no longer play in browsers. Converting to MP4 rescues them for any modern device.
- Drop your FLV file into the box above, or add it from a link.
- MP4 is already selected. Use the settings button next to it to change size, quality or other options.
- Select Convert, then download your MP4 file.
To do this from your own code, call the FileForge API with "output_format": "mp4".
Good to know
- Old FLV files are often low resolution; converting won't increase detail.
- The MP4 plays in every browser, phone and editor.
About the formats

FLV is the Flash Video format from the days of Flash players. Flash is gone, so FLV files now need converting to play in browsers and on phones.
.mp4
MP4 is the most widely supported video format. It plays on practically every phone, browser, TV and editor, usually with H.264 video and AAC audio inside.
Questions
Can I still play FLV files?
