How to Compress FLV Files Free | 3 Easiest Ways

Just like MP4 at present, FLV was once one of the mainstream video formats and is frequently used as a media on the internet. However, your FLV videos can be large if they are saved as a file in 1080P and of higher quality, resulting in difficulty uploading or sending them in an email. Hence, knowing how to compress FLV files is essential. This post will tell you the three easiest ways to compress FLV on Windows and online.

Words Before Compression

๐Ÿ“Œ What is FLV File?

FLV, short for Flash Video with the extension of .flv, is a video introduced by Adobe Flash Player. Also, it is a container file format used to deliver digital video content (e.g., TV shows, movies, etc.) over the internet by Adobe. Meanwhile, there are two different Flash Video file formats: FLV and F4V. The audio and video data within FLV files are encoded like SWF files, while the F4V file format is based on the ISO base media file format, starting with Flash Player 9 update 3. Both formats are supported by Adobe Flash Player and developed by Adobe Systems.

๐Ÿ“Œ How to Open FLV Files?

Adobe Flash Player can usually open an FLV video. For the Windows system, you can open it with a built-in program–Windows Media Player or FLV Media Player downloadable in the Microsoft Store. Additionally, you can resort to other third-party video players like VLC and Winamp to open it.

๐Ÿ“Œ Why Do You Need to Compress FLV Files?

An FLV file is generally less large than an MP4, AVI, or WMV video. However, it will sometimes be too large for you to upload effortlessly onto your personal website/social media platforms or send it through an email conveniently. Therefore, it is important to master the skill of reducing FLV file size.
