How to convert MPEG to FLV

  1. Add your .MPEG file - drop it in the box above or click to browse.
  2. Convert it to .FLV in a few seconds.
  3. Download your new .FLV file.

What to expect

  • This is a re-encode, not a remux - MPEG video must be decoded and re-encoded to H.264, which always loses a small amount of quality.
  • FLV is a legacy Flash format; Flash reached end of life in December 2020 and modern browsers do not play .flv natively.
  • Files with the .mpg extension are the same format as .mpeg and convert identically.

Frequently asked questions

Is FLV still worth using?
Rarely. Flash is dead as of December 2020 and modern browsers do not support .flv playback. Only convert to FLV if a specific legacy player or RTMP server requires it - otherwise MP4 is the better target.
Will the conversion lose quality?
A little. MPEG video must be re-encoded to H.264 to fit inside FLV, and any re-encode discards some detail. In ffmpeg, a lower -crf value such as 18 gives higher quality at a larger file size.
Can VLC convert MPEG to FLV?
VLC can re-encode files via Media > Convert/Save, but its FLV presets are limited. The ffmpeg command gives a cleaner, more reliable result.
Does it matter whether my file is MPEG-1 or MPEG-2?
No - both variants need to be re-encoded to H.264 for FLV, so the conversion process is identical regardless of which you have.
