This article developed by MiniTool Software Limited mainly introduces the famous video compressors for Instagram for different operating systems. It also teaches you how to operate a video compressor to reduce the size of a video.

What Is a Video Compressor

To learn what’s a video compressor, first of all, let’s see the definition of video compression. Video compression is the process of reducing the total bits that are required to represent a given image or video sequence.

Video compression is usually performed by an application that has a specific algorithm or formula to determine the best way to shrink the data size. Such an application is known as a video compressor app or video compressor software.

Audio Compression

Typically, audio is compressed for the efficiency of resource use. Video compression is also very beneficial for the efficient usage of storage thanks to the largely shrunk file sizes. Compression technologies are applied extensively across all elements of current network and computer architectures.

In general, compression is the process to pack file information into a smaller space. The tool that completes the task is named a compressor. The program that can pack a video is called a video compressor while the app that can pack audio is called an audio compressor. Yet, usually, a program that can pack a video can also pack sounds. So, a video compressor is also an audio compressor in most cases.

What Can a Video Compressor Do?

Just as mentioned above, a video compressor or video resizer/reducer/shrinker/cutter is able to reduce the total number of bits needed to display a specific graphic using its algorithm like H.264/AVC or H.265/HEVC, which reduces the raw content data by as much as 1 thousand times.

For real-time video, HD 1080p 60fps has a natural baseband bandwidth of 3 Gbps. Once it is compressed, the resultant network video stream can be as low as 1 to 10 Mbps, which enables the real-time video streams or the resultant files to be easily delivered across today’s standard Internet.

Video compression can be sorted into two kinds: lossy compression and lossless compression.

Lossy Video Compression

Lossy compression refers to that the compressed file has less data than the original file. Images and sounds that repeat throughout the video might be deleted to effectively cut away parts of the video that are regarded as unwanted. Thus, that process may finally get a lower-quality video due to data loss. So, it is called lossy compression.


The lost data can’t be restored.

The advantage of lossy compression is that you can reduce a large amount of data before a quality loss is sensible. Thus, most video files are uploaded to the Internet or online social media platforms like Instagram, YouTube, TikTok, Facebook, Twitter, etc. with lossy compression to keep a small file size while delivering a relatively high-quality image.

If you upload a video keeping an extremely high-quality (large file size), it will take forever to upload the video, and even if you finally manage to upload it online, the viewers will probably get stuck watching your video online or downloading it to local computers.

Lossless Video Compression

Being different from lossy compression, lossless compression nearly won’t remove info from the source video files. The compressed and the original files are almost identical, as is the file size. Therefore, the cases to use lossless video compression is few.
