The next thing is image compression which plays a huge role in image optimization.
There are different types and levels of image compression available. The settings for each will vary depending on the image compression tool you use.
Most image editing tools like Adobe Photoshop, On1 Photo, GIMP, Affinity Photo, and others come with built-in image compression features.
You can also save images normally and then use a web tool like TinyPNG or JPEG Mini for easier image compression.
Although it’s a bit manual, these two methods allow you to compress images before uploading them to WordPress, and this is what we do on WPBeginner.
There are also several popular WordPress plugins like Optimole, EWWW Image Optimizer, and others that can automatically compress images when you first upload them. Many beginners and even large corporations prefer to use these image optimization plugins because it’s easy and convenient.
We will share more about these WordPress plugins later in the article.
