How to Compress a Video File: Tools for Reducing Video Size

Before knowing how to compress a video file, you must know what video compression is. Some file-sharing services hold a sort of file size limit.

Compressing video files assists you to fit beautiful and dynamic content into your message without losing quality or taking a lengthy download period on the users’ end.

Video compression happens by removing unnecessary sounds and repetitive images. Depending on the original size of the video, it usually indicates overall quality takes a hit. Although, for the individual eye, the quality loss may not even be noticeable.

What are the suggested resolution and aspect ratios to fit the player perfectly? 

We produce digital files with bytes — kilobytes (1024 bytes), megabytes (1024 kilobytes), gigabytes (1024 megabytes), and terabytes (1024 gigabytes).

Your digital file’s bytes will depend on several factors, including format, length, and resolution, directly related to the reproduction quality, how we explain below.


Video types — such as MP4, FLV, WMV, AVI, and MOV — can affect the overall size and quality. While some file types offer better codecs, such as MP4, others are less effective and result in a poor compression file, such as an FLV.


A video that lasts a few minutes will be smaller than a video that lasts hours. So, the file type selection can also impact the ratio between video lengths and file size.


Frame rate — also named FPS (frame per second) — and resolution influence both file size and the video quality: the more frames you have, the more detail you will expose, and the more significant your file will become.

Even videos shot in 240 FPS can be reduced down to 24 or 30 FPS. The average resolution of a video in HD is 1080 pixels (1920×1080), the recommended rate for YouTube videos.

Resolution is usually represented by a horizontal × vertical measurement of the number of pixels displayed in a video. A high resolution doesn’t certainly mean the highest quality level, but how large an area the video can fill.

A 1-minute video, for instance, recorded in 4K or Ultra HD (3840×2160) will have a 2 GB file size, while one video in Full HD (1920×1080) will have a 403 MB file size. Most video editing software will let you keep your resulting file format.

Other technical features of videos are codecs — it removes useless or repetitive sounds or images from a large video file. Actually, it shrinks your file down for storage and then decompresses them again to ensure their view.

If you want to know how to compress a video file, you must get it. Fortunately, codecs work automatically within the software wanted to compress a video file. There are the following types of codec:

  • MPEG — it occurs in high-quality video playback even after compression.
  • ProRes — it provides a better color resolution for videos.
  • WMV — it’s primarily used by Microsoft video editing software.
