Video has taken over the web. In the past, internet speeds were too slow to make the widespread use of video possible. Today’s technology, however, allows for video content to be readily shared. Video marketing and creation are becoming the front and center of every businesses’  content and communication plan. Anyone can create professional video content using our online video maker – they can even add royalty-free music and other elements with ease. But there is one issue that needs to be addressed – video files are huge! And cropping videos – like with our video cutter is just not enough. Using a video compressor – or, better yet, a free video compressor can help bring files down to manageable sizes.

Yes, modern internet speeds can often handle loading and playing big files, but they still need to be stored somewhere. Reducing video file size is attractive for several reasons. This brings us to the focus of this article – the best online video compressors. Compressing a video involves reducing its file size, and there are plenty of great tools available for the job.

How Does Video Compression Work?

In general terms, video compression works by eliminating or reducing redundancy in video files. In other words, rather than having information for every single thing that takes place in the video, a compressor shrinks the file size by doing away with redundant information. For example, if a large section of the video is filled with a solid background color, there is no need to retain information for each pixel in that area. 

By getting rid of repeat information, the same video can be produced from a significantly smaller file. Without going through the compression process, your files will be needlessly large. You’ll deal with slower loading times, poor streaming performance, and more. 

  • Identify Pixel Pattern

It’s common for pixel patterns to appear in video files. It would be unusual if a pattern were not present in one form or another. These patterns can be identified by a video compression tool and can be used to reduce the amount of information required to save the video. Getting rid of excess information through identifying pixel patterns is one of the key methods used by quality compression tools to bring video files down in size without sacrificing quality.

  • Remove Excess Information

The way information is organized within a file determines how much space is needed to store it. Another one of the functions of a compression tool is to remove excess information and reorganize the remaining data in a way that minimizes file size. Just as you may make more space in your house by reorganizing your things – even if you don’t get rid of anything – a compressor can allow a video file to take up less room just by correctly and efficiently organizing its contents. 

  • Reproduce Video Frames

There may be entire frames that are repeated as the video recording was taken within a video. This is the case in a setting where movement is slow, causing many frames in a row to have the same data. Instead of keeping the data for all of those individual frames – despite having the same information and producing the same image – the video compressor can eliminate the duplicates and just reproduce the repeated video frames as often as necessary to achieve the same result. 

Top Reasons to Compress Videos

Working with video would be simpler if you didn’t need to worry about compression. You could just capture the video, edit it as desired, and use the finished file to distribute the content to your intended audience. That would be easier – but you’d be missing out on some important benefits by skipping the compression step.

So, why is compression so crucial in many applications? Let’s look at some of the notable benefits of using a video compressor to tighten up your files.

  • Save Disk Space

This is the prominent place to start. If you are storing your videos locally – that is, on your machine, like a desktop computer or laptop – having big files is quickly going to bog you down. If you handle a lot of videos, your disk will fill up, and you won’t have anywhere left to store new files. Even if you manage to maintain open disk space, the performance of your computer may slow down due to the crowded storage. There is also the option to use cloud storage, but you can quickly run out of room on a cloud account, and then upload and download times may be miserable if the files are huge. Compressing your video files down to a more manageable size makes all these issues less of a problem.

  • Faster Loading Speed

We referenced this benefit in the previous point, but it deserves a point of its own. When dealing with videos used on the web, upload and download times are something to consider. Even with a strong internet connection, a huge video file can take a long time to transfer. For someone who deals with video daily, all those loading times can add up. Just think – if you could save 30 minutes a day by loading your video faster, what could you accomplish with that newly found time? This can also have a compound effect in an office setting where various team members need to download the video file to work on it before uploading it and sending it along. When files are smaller and can be loaded faster everyone benefits.

  • Faster Streaming

When someone else is viewing a video that you have offered up online, they are likely to stream that video to their device (rather than downloading it). Streaming a smaller file will be easier than streaming a large file, and those with lesser internet connections will still get good results. Additionally, if you make your videos available to download, it will be easier for your audience to complete those downloads when the file sizes have been reduced.

Any way you look at it, compressing video files is essential. Even if video compression only provided one of the benefits listed above, it would still be worth it. Considering that it brings all these benefits, and even more, to the table, making this part of your process is a no-brainer.

  • Lessens the Server Load

If you run a website and host videos on that site to share with your audience, shrinking the size of the videos will save space on your server. This has a couple of essential benefits. First, with fewer data stored on your server, your site should be faster – and a faster site is suitable for user experience, search engine optimization, and more. Additionally, keeping your server storage to a minimum is helpful because it can save you money. Your web hosting company will almost certainly charge you more if you need additional storage space for your site. Taking the time to compress all your videos could be the difference between making your current hosting plan work and needing to upgrade to a more expensive tier.

  • Eliminate redundancy

Fortunately, you don’t have to be an expert on the behind-the-scenes details of how computers and video recordings work to make great videos. Most of us don’t have an in-depth understanding of what’s going on behind the scenes when we interact with technology, and that’s just fine. It can be helpful to understand the basics, however, so let’s take a quick look at how videos are compressed.

As you already understand, the goal of video compression is to reduce the size of the file. To make that happen, the primary purpose of video compression is to remove redundancy. When there is repetition within the video – say, the same sound occurs several times throughout the recording – those repetitions can be eliminated since only one version of the sound is needed to serve the file. If there are enough redundant images and sounds to stop, the size of the file can be dramatically reduced.

What to Look for When Choosing a Video Compressor

As you prepare to use a video compressor for the first time, or as you look for a new tool to be your go-to option, it’s easy to get lost in a sea of choices. There are countless online video compressors available today and plenty of others that can be downloaded to your computer. So, how do you know when you have found the right one for your needs? Here are some key points to keep in mind.

  • Cost: Free vs. Paid

If you are just getting started, look for a free tool to use for your first few compressions, at least. Most of the tools available today will let you use them for free in some capacity. However, the free version may be limited regarding how many video files you can compress or the various features you can access. It makes sense to get started at the free level so you can test things out without committing any financial resources to the project. Once you get the hang of it and see which tool you like best, it may be worthwhile to purchase the premium version to make the device even more useful.

  • File Types

 Be sure to review the file types that a given tool accepts for inputs and creates as outputs. You’ll need to choose a tool that covers the types of files you plan to use and create. Most of the tools you find, including those we have listed below, cover the most popular kinds of files used today. These include not only video file formats like MP4 but also audio files like MP3 and image files like JPEG and GIF. Even if your focus is video, it might be nice to get comfortable with a tool that can also do compression and conversion work on other types of files you may encounter.

  • Maximum Video Size to Upload

The idea of a video compressor is to reduce the size of the video file, of course, but you need to watch out for the starting size of that file and whether it fits within any limits set by the tool you want to use. Some of the conversion tools available – especially those that are free – will put a cap on how big your video file can be before it is compressed. Choosing a tool with no limit or a very high limit will give you more flexibility.

  • Ease of Use 

It’s important to remember that compressing your videos will be just one of many steps that you need to complete when producing a new video from start to finish. As such, you don’t want to be bogged down with a long, complicated process just to trim down these file sizes. You may want to try out a few different tools to see how they perform and ensure that ease of use is one of your top criteria. You are more likely to compress all your videos when you have a tool on hand that is quick and easy to use.

  • Compression Quality

It might go without saying, but all of this work to compress a file will be wasted if the finished product is of a low quality. You’ll want to make sure any compressor you rely on for regular work can shrink the file size without damaging the quality of the finished product. As you get started trying out a few tools, be sure to test out the quality of the compressed files to confirm that they meet your expectations. 

Given that you should be starting with the accessible version of some online video compressors, there is no reason to spend too much time debating which one to use. Consider the points listed above and simply get down to the business of performing compression on a video file that you have available.

Video Compression Tools Frequently Asked Questions

If you have some unanswered questions about video compression tools, you might find the answer to those questions here.

Q: What is Lossless Compression?

A: You are likely to encounter two types of compression options as you examine various tools – lossy and lossless. As the names might lead you to believe, the lossless version works to maintain the entire quality of the original file, while lossy give up something in terms of quality in exchange for file size. Generally speaking, it is lossy compression that you will want to use to shrink your video files. Maintaining 100% of the quality of the file with lossless compression sounds excellent, but you won’t end up saving much (if any) file size in the end. Lossy compression is the standard approach, and in most applications, any decrease in quality won’t be noticeable when you view the video from the new, smaller file.

Q: Is a free tool good enough to compress my videos?

A: This answer will depend on your needs, but many users will find that a free tool fits their requirements. Many free tools have some limits on file size or the number of files you can compress – but those limits might not stand in your way. There is nothing inherently “better” about a paid compression tool than a free one, as they both work the same way. The only difference comes in the form of additional features or the removal of restrictions. Get started with a free tool and choose to pay for one later if the need arises.

Q: What file format should I use for my compressed file?

A: Unless you have a specific reason to use another format, MP4 is the modern standard and should be your target. Many of the compression tools will have the MP4 file format selected as the default option, given its tremendous popularity. You may occasionally work on a project that demands another type of file format, but MP4 files will serve you well for most projects.

Q: How long does it take to compress a video file?

A: The time it takes to complete a file compression depends on the size of the original file. The bigger the file, the longer you can expect the process to take. If you are using a web-based tool, the speed of your internet connection will impact this time, as well. If you would like to perform conversions quickly and you don’t have access to consistently fast internet, you may want to opt for a conversion tool that you can download directly to your computer. In that case, your conversion times will only be limited by the capabilities of your computer and not the internet connection.


Video compression is just part of the deal when working with video files online. Once you get familiar with some of the best online video compressors and you understand how they work. This step won’t take up much time in your overall process. We hope the information in this article, including the sections that highlight some of the top tools in this niche, will help you make quick work for any compression work that you need to complete.
