Part 1. What is Image Compression?

Image compression refers to a technique in which an image is minimized in size and compressed so that it occupies a small space on a computer’s disk. While at the same time still being clear and high-quality.

Here, the objective is to reduce the image size and consequently the size of the file to be loaded and displayed as much as possible. It helps to achieve faster loading time without losing the quality of the image.

Before moving further let’s try to understand with an example how image compression works. Suppose you have an uncompressed image, and this image file size is 5 MB. Even after applying the compressing techniques to the image, it may reach a size of 1 MB and still, it is relatively impossible to distinguish any difference with the naked eye. Here is a comparison example.

Part 2. Benefits of Compressing Images

Compressing images online comes with multiple benefits including the following:

· Improved Website Loading Speed

This is an effective way to improve website loading speed. Long time to load the page makes internet visitors leave your site without going deeper into the page, hence, increasing the bounce rate. Applicable to the case of e-commerce websites this may go hand in hand with the increased generation of conversions since the users can easily browse and view goods.

· Reduced Storage Space

Compression helps in the way that the file sizes of images are reduced, and therefore occupy less space on a server. This proves to be particularly helpful in the case of websites and applications that require efficient organization of large numbers of images. This way, the storage would be cheaper as well as the data would be properly managed.

· Lower Bandwidth Usage

Small image sizes are also useful because they require less bandwidth, meaning websites with a large amount of traffic benefit. Less bandwidth consumption is beneficial not only in terms of cutting costs but also because your website will be easily accessible and load quickly from any connections that are slow or contain limited data allowance.

This can prove helpful for example for mobile users who usually get a slower connection to the internet.

· Improved Seo Results

This is important because when the website is loading fast, the search engines will rank it taking little time to open and making it as simple as possible for the user to navigate. Compressing images that can help to lower the time it takes for your webpage to load will also influence your search engine rankings.

Moreover, fast websites are better indexed through search engine bots and thus have a boost in rank regarding SEO. This leads to better visibility, improved quantity and quality of the website traffic, and therefore more clients or customers online, which will in the end lead to business development.

Part 4. Other Tips

Using the right compression practices helps you get better results and here are some expert tips that may help you achieve better results.

· Choose the Right File Format

The type of format you choose for your image is important when compressing your images. JPEG images are great for photographs as it has both quality and size, but PNG is better for images like logos that need transparency or a lot of detail. On the other hand, WebP has a better compression ratio for both the lossy and lossless web images giving it the versatility to be used for a variety of visual and graphic images.

· Understand Compression Quality vs. size

The compression process is applied at the cost of the quality and size of the file. All the image compression applications expose a quality of compression parameter. A lower compression ratio allows smaller file size, but you lose the quality of the image. The goal is to achieve minimum image size, meanwhile, the quality is not significantly affected.

You need to understand that there are different compression levels and if you set the low level of compression the image will take less disk space but, it will not be of good quality while if you use the high-level compression then the quality of the image will be very good but the disk space required for storing it will also be high.

· Resize Images to Scale

Sometimes pictures are copied with much more clarity than is needed. Adjust your images’ sizes to the necessary sizes before compressing them as it’s more effective to do them together. Reducing does not only make the file size minimized it also guarantees that images will load fast and be properly shown on a website or application.
