About FLV Files

.flv Icon

An .flv file is a video file saved in the Flash Video (FLV) format, a container format developed by Macromedia (later acquired by Adobe) for delivering digital video over the Internet using Adobe Flash Player. FLV files typically contain video encoded with the Sorenson Spark or VP6 codec and audio encoded with MP3 or AAC. Macromedia introduced the FLV format in the early 2000s, and it became one of the most widely used formats for streaming video online, powering early video platforms like YouTube, Hulu, and VEVO.

Due to its small file size and ability to stream efficiently over slow connections, many websites adopted the FLV format to deliver video content. However, usage of the format dropped significantly with the decline of Adobe Flash and the rise of HTML5. Modern platforms now use formats, such as MP4 and WebM, for broader compatibility and mobile support. While Flash Video is mostly obsolete today, many video converters and media players still support .flv files, allowing users to access or repurpose older content.

Converting FLV Files

You can convert .flv files to more modern formats for improved compatibility with devices, browsers, and video editing software:

  • Converting to MP4: Offers excellent compatibility and efficient compression, making it ideal for web use and mobile playback.
  • Converting to MOV: Enhances performance in Apple environments but may increase file size depending on compression settings.
  • Converting to AVI: Suitable for use with older editing tools, though it may lack support for streaming and modern features.
  • Converting to MKV: Preserves video quality and supports advanced features like subtitles and multiple audio tracks, but may not be natively supported on some platforms.
  • Converting to WMV: Improves compatibility with older Windows applications and devices, but may result in reduced quality or limited feature support compared to newer formats.
