How to Compress a Video the Smart and Easy Way

How to compress a video

Video files get bigger and bigger, and nobody is surprised when YouTube, Facebook, and Vimeo support 4K videos for everybody to watch and upload.

In addition to that, our cameras and mobile phones shoot more and more videos every day. Now, source video files can be from 10Mb to 10Gb for a minute of 1024p video! The most surprising part, though, is that the quality of the video can be almost the same.

Sooner or later, you need to answer the question: how to have high-quality video and keep it as light as possible?

Here’s where video compression comes into play.

Whether you want to upload your videos online or keep your family video archive intact, learning how to compress a video is vital.

Nowadays, the question of how to compress a video is very important, whether you want to upload your videos online or keep your family video archive and not run out of space.

If you’re new to video editing, many of the existing parameters of video can be very confusing. Moreover, compressing videos can require some extra knowledge about video formats (if you don’t use, which is optimized for people without any video editing experience).

In this article, you will find the basic vocabulary as well as everything else you need to know about video compression, video compressors, and 4 free tools to compress your videos for any goal you have.

Let’s start with vocabulary

Here’s a helpful vocabulary that will help you learn your way around the world of video compression.

Master version – uncompressed version of your final video, usually weighs a lot.

Frame rate / FPS – Number of frames per second.

Video dimensions – Width and height of the video. For videos, it measures in pixels, here are the most popular horizontal ones: 426 x 240 (240p), 640 x 360 (360p), 854 x 480 (480p), 1280 x 720 (720p), 1920 x 1080 (1080p), 2560 x 1440 (1440p) and 3840 x 2160 (2160p).

Aspect ratio – The aspect ratio of an image describes the proportional relationship between its width and its height.

Media codec – computer program used for compressing and then decompressing a video file.

Video container – file systems designed to interface between the OS (operating system) and the video data. I bet you’re familiar with many of them: .avi .mp4 .mov .mkv and etc. Container can store the video data and audio streams, subtitles, video metadata, codec and more.

Video bitrate – another important metric corresponding the number of bits that are transmitted over a set length of time. In professional programs like Adobe Premiere/After effects you can even customize bitrate encoding setting (Constant BitRate, Variable BR 1 pass, VBR 2 pass, CRF) different target and maximum bitrate and see how different the final file size can be.

What is video compression?

Basically, video compression is the process of making your videos smaller by packing and reducing your media data (audio, video, meta-data).

Here are just a few parameters that you can customize in your video compression software to achieve different levels of compression:

  • FPS
  • video dimension
  • aspect ratio
  • video bitrate
  • audio bitrate

Technically, video compression can be of two types: lossy and lossless.

Lossy video compression

Lossy compression means that a compressed file will contain less data than the original one. It’s the most efficient way to compress your video files to a smaller size.

The downside: it can cause image quality loss. If you keep using this video compression type progressively, you’ll see more loss in quality (visible pixelation, motion distortion, etc.)

How to compress a video

Example of a 6-minute video lossy compression with the same codec and container (.h264, .mp4) but with different data bitrate. Notice the visual loss of data but a smaller file size.

Lossless video compression

Just as it says on the tin, it’s a type of video compression that reduces metadata with no loss of data. In the end, you get video files of almost the same weight.

Unlike irreversible lossy compression, when you go with lossless video compression, the original data can be reconstructed from the compressed file.

With lossless video compression, you will be able to restore the original data from the compressed file.

It’s a good practice to keep the master versionMaster versionUncompressed version of your final video, usually weighs a lot of your video compressed with lossless compression.

When we speak about digital video files or so-called “video formats” that you can find in many articles, they consist of two parts: video data with codec info and a container.

How to compress a video

Many containers can be compatible with different video codecs. That’s why sometimes your video file cannot be played on some computers until it has a suitable codec installed.

How to compress a video: best practices

For most cases, we recommend using one of the following popular codecs:

  • H.264
  • H.265 (HEVC – High-Efficiency Video Coding)
  • Apple ProRes 422, 422LT

The full description and comparison of codecs you can find here.

The most popular containers to use:

  • .mp4
  • .mov (mostly using Apple codecs)
  • .mkv (matroska)

Other formats have many limitations, the full list of containers you can find here.

Pro tip: 

Many of online multimedia projects, including YouTube and, use FFmpeg software as one of the most powerful collections of libraries, codecs, formats, and programs for handling video, audio, and other multimedia files and streams.

Using this technology, offers compressed video files using .h264 codec and .mp4 container with up to 1024p resolution, 24fps, and variable optimal bitrate for obtaining the best quality with a smaller file size. And all of that online!

Feel free to use 480p or 720p resolution and variable bitrate of up to 1Mb max for the following use cases: 

  • if you need to email a video preview
  • if you want to send a video via a messenger
  • the idea of the video is more important than the quality

For other purposes it’s always a good idea to try different parameters, compare the quality and the file size to choose the best one for your needs.

Now that we understand different types of video compression, let’s move to the most important part: how to compress video files and which video compressor to choose.

4 free video compressors

Needless to say that almost all editing programs offer video compression functionality. However, I found these 4 video compression tools to be worth using. (online) is an online platform, so you won’t need to download software to your computer. Thanks to’s online video editor, you can easily upload your video and change its format, resolution, and quality within a few clicks.

Here’s how to do that:

  1. Sign up to, upload your video file, and open it in the editor
  2. If needed, edit your video (you can add text, music, resize video, etc.) and then head to the publish button on the top right
  3. Choose a new resolution, quality, and video format for your video and hit the “Render” button

Good to know:

If you want to upload your videos online and achieve the best quality, please respect the encoding settings of the platform. For instance, here are the specs from YouTube:

  • Container: MP4
  • Codecs: H.264, AAC for Audio
  • Resolution and aspect ratio: 16:9
