How to convert FLV to MP4

  1. Upload your FLV file above.
  2. Keep MP4 selected as the output.
  3. Choose Balanced quality unless your workflow needs another setting.

  5. Start the conversion and download the finished file when it is ready.
Before you convert

Modern browsers and devices generally prefer MP4 or WebM. Re-encoding can change quality and file size even when the extension stays familiar.

Changing a container or codec cannot recreate quality already missing from the source, so keep an important original when possible.
