What Is Image Optimization? Is It The Same As Image Compression?

What Is Image Optimization? Is It The Same As Image Compression?

Image optimization is reducing the file size of a digital image without compromising its quality. This can be done by using various techniques, such as choosing the correct file format, compressing images, and using proper sizing. By doing this, you can ensure that your images load quickly and efficiently on your website or blog. Search engines consider page load time when ranking websites in their search results. So, by optimizing your images, you can also help improve your website’s ranking.

Image optimization is not the same as image compression. Image compression involves reducing the file size of an image, typically by removing unnecessary data or using data compression algorithms. Image optimization, on the other hand, refers to increasing the efficiency of an image file without necessarily reducing its file size. In WordPress, image optimization can refer to optimizing images for better web performance and optimizing images for better search engine visibility.

Which Image Optimizer Plugin Is Best For You? Final Verdict

There are a lot of similarities, as you can see. This makes sense because the plugins sometimes employ nearly identical compression algorithms. Which WordPress image optimizer is, therefore, the best for your website?

We found that TinyPNG and Imagify’s pricing models are very competitive if you’re looking for premium options that provide a range of features. Depending on the size and usage of your website, they only differ slightly. But because Imagify offers a more significant number of components than TinyPNG, we will advise using it instead.
