8 Best Free Open Source Video Compression Software For Windows

Here is a list of best free open source video compression software for Windows. As these are open source video compression software, thus you can download and edit respective source code of these freeware.

Through these software, you can easily compress or reduce the size of a video without heavily reducing the video quality. However, none of these compressors come with a dedicated video compression feature. To perform video compression, these software let you reduce the bitrate and frame rate of a video. By lowering the video bitrate, you can reduce the video quality a bit that translates into the reduction of video size as well. Similarly, by reducing the frame rate to around 24 FPS from the default 30 FPS, you can achieve some video compression. However, the level of video compression can vary from software to software even if you are using the same video bitrate and frame rate values. The process of video compression is not that hard. To help you out, I have included the video compression steps in the description of each software.

In some of these compressors, you can also edit videos by using provided editing tools like timeline editor, split, cut, join, etc. Plus, options to change the video format, resolution, aspect ratio, codec. etc., are also present in most software. Along with various features, these software also offer support form many video formats like MP4, AVI, MPEG, FLV, MOV, MKV, and more. Go through the list to know more about these software.
