What is FLV?

FLV (Flash Video) was the dominant video format for web streaming during the 2000s. Developed by Adobe (originally Macromedia), it powered YouTube, Vimeo, and countless websites before HTML5 video emerged.

FLV files require Adobe Flash Player to play, which Adobe officially discontinued in December 2020. All major browsers have removed Flash support, making FLV files unplayable in modern web browsers.

If you have FLV files from old websites, downloaded videos, or archives, converting them to MP4 is essential to preserve access to this content.

Why Convert FLV Files?

FLV conversion is now mandatory since Flash Player no longer exists:

  • Flash is dead – Adobe discontinued Flash Player in 2020; browsers removed all support
  • No native playback – No modern browser, phone, or TV can play FLV files
  • Security concerns – Flash had numerous security vulnerabilities
  • Preserve content – Old FLV videos will become inaccessible without conversion
  • Better quality – Modern MP4 compression is superior to old FLV encoding
  • Share anywhere – MP4 works on all platforms; FLV works on none

Convert FLV to Other Formats

Save your Flash videos by converting to modern formats:

FLV to MP4

The essential conversion for FLV files. MP4 replaces FLV as the web video standard and plays everywhere Flash no longer works.

FLV to AVI

Convert for Windows video editing and legacy media player compatibility.

FLV to MOV

Transform for Apple ecosystem compatibility and professional video editing.

FLV to MKV

Archive FLV content in MKV format with support for metadata and multiple tracks.

FLV to WebM

Convert to the open web video format that replaced Flash for HTML5 video.

FLV to MP3

Extract audio from Flash videos as MP3 files. Great for music videos and podcasts.

Convert Other Formats to FLV

Creating FLV files is not recommended since Flash is discontinued. Convert TO modern formats instead.

MP4 to FLV

Only useful for very specific legacy systems that still require Flash video format.

Expert Tips for FLV

Pro Tip

Many old FLV files from early YouTube or Flash websites are historically significant. Convert them to MP4 immediately—as Flash fades further, finding tools to read FLV may become difficult.

Common Mistake

Trying to install Flash Player to watch FLV files. Flash Player is discontinued and a security risk. Use VLC to play FLV files, or better yet, convert to MP4.

Best For

FLV was designed for Flash-based web video streaming. Today it's only encountered in old video archives and downloaded content from the 2000s-2010s era.

Not Recommended

Never create new FLV files. Flash is dead and FLV has no advantages. Always use MP4 or WebM for video today.

technical description
FLV files mostly have video bitstreams which are one of the variants of H.263 Standard and it is named as Sorenson park(FourCC FLV1). The SWF files and this extension uses the identical way to encode data. There are two variants available for screen casting. First one is lossy as it reduces colour depth or bit depth (number of bits used to indicate the colour of one pixel) and compresses the data. The second type is only compatible with Flash Player 8 and the newer versions. Both these aforesaid kinds are based on bitmap tile. Uncompressed Audio or ADPCM format audio is also supported by it. This format has header and packets in its video structure. A standard header includes signature, version, flags and header size.
