Why convert FLV to MP4?

Reuse a downloaded FLV recording as an MP4 file. This tool converts video files, not interactive Flash applications.

  • Why leave FLV. Browsers dropped Flash, so modern apps and phones rarely open FLV.
  • Why use MP4. MP4 suits sharing, uploads, phone recordings, and web playback.
  • What you get. The converter first tries to copy the video and audio without compressing them again. If that fails, it encodes H.264 video and AAC audio. Keep the original. The converted file can differ in size and metadata, and some apps may still not play it.
  • Kvalitet. Converting FLV to MP4 often keeps the quality. The converter first tries to copy the video and audio without compressing them again. If it has to compress them, it uses H.264 and AAC, which can lower the quality a little. It never adds resolution or detail.
  • Your rights. Convert only files you own or have permission to use.
