What is Image Compression?

Image compression does not have to be complicated. As long as you have a basic understanding of the plugins, you can have the software do all the heavy lifting.

To put in easy terms to understand, you compress an image when you make it smaller. Once the file size is lowered, you can load in images much faster. How can we lower the size of an image though? After all, the Mona Lisa would look much worse if it was missing the background or the border around the image.

When you compress your image, you group together parts of the picture. This could be based on color for example. The algorithm will scan for the color black and group pixels together based on a standard that equates to the color black when we look at it. Now if you can group together a large chunk of the file together, it makes it simple and easier to upload or download. Instead of many different parts of the pictures now, you have less pieces to think about.

Benefits of Compression

When you are grouping parts of the picture together based on certain criteria, you may also find the algorithm will remove parts of the image as well as it makes those groupings. Not every part of the image is needed if you can have a close approximation. You may lower the detail, but it is acceptable if the human eye can not detect a difference and the site loads faster. Looking at the advantages of compression, we have the following:

  • You may have a high bounce rate if you never compress images. If your image heavy site loads slowly, visitors will bounce out of it and skip your site.
  • Moving images around. If you ever need to backup your images and your site, it will take much longer when you have uncompressed images.
  • It is easier to move elements on your website. Maybe a client wants to see a video or selection of images from your site. Moving things to a drive will be much harder if nothing has been shrunk down.

These are just a few reasons why you want to reduce the size of pictures you are working with. While it might seem like some of these things are small, it can add up big. When a client needs a site done quickly or a video has to be done in a hurry, compression may be your only option if you want to get things completed by a deadline.

Kinds of Compression

Is all compression the same? Does it always work the same way? The answer is no. Compression can differ and change. Let’s look at some of the more popular types.

Lossless

With this type of compression, you will reduce the size of the image, but you will keep the same quality. If you have a DSLR camera, you may have already run into lossless compression and not realized it. A number of DSLR cameras will use a format for the images known as RAW. This keeps track of all the light data that was absorbed by the sensor. The file size with RAW will be large, but that is the trade off that you pay when having lossless images.

If you contrast a RAW file with a JPEG, the difference is huge. The JPEG files will download and upload faster and also fit on your drive in a more compact fashion, but the RAW files will have better quality. If you are going for a large print or a professional movie poster that will be blown up to a large degree, you will want to go with a form of compression that will shrink the size of the file while still leaving in enough detail to match the application.

Lossy

Next, we want to take a look at lossy compression. As the name implies, something is lost from the picture, but you get an even smaller size. Grouping together parts of the photo based on criteria such as color will lower contrast and how sharp the image is. This makes sense. If you group together pixels based on a certain shade of black and combine them into one part of the file, you lose that gradient. There won’t be as many subtle shifts in color and form since the algorithm looks to homogenize together pixels it considers similar.

The advantages with lossy compression is that it will be much easier to manage your image files. You won’t be able to blow up the images to a huge size any more since the degraded quality will be detected, but you will be able to fit more images on a Solid State Drive or any other storage device. Your site will also load faster now and possibly give you an advantage over the competition.

Common Forms of Lossy

You may assume that as parts of the image are taken out, people will notice and complain. This is not accurate. When you browse sites on the web, many of the images are JPEG images which is a type of lossy compression. If you use the standard amount of compression few people will be able to notice the difference.

Another type of lossy compression you are probably familiar with is a GIF. We have all sent them to friends and family with a phone. A small animated loop can say a lot with just a second or two to run. Once again, when you are looking at a GIF image, you can still clearly see the level of detail is there. As long as you don’t use an extreme level of compression, you can save space on your drive and still get the desired result.
