The procedure for optimizing images for websites is actually more complicated than it seems at first glance. It is often believed that it is enough to compress the image, but this is not true.

Proper optimization should ensure the following criteria:

Uniqueness of the drawing/photograph.

Image compression (reducing its size).

Removing unnecessary data about image properties.

Correct scaling of a drawing/photograph on a web page.

Ensuring optimal image format.

Correct coloring.

Let's look at each of the criteria presented here in more detail.

Uniqueness of the drawing/photograph

Webmasters are not fighting for the uniqueness of images on websites as actively as for the uniqueness of texts. But gradually the movement for compliance with this requirement in relation to images is gaining momentum. In its vanguard is the resource Tineye.com. Many webmasters use this resource, since with its help, optimization of images for the Web according to the criterion of "uniqueness" is carried out quickly and easily.

Reducing the size of an image (compression)

This is the main criterion in the list of elements for optimizing photos for a website. From the point of view of search engines, the photo should have minimal dimensions. But at the same time, it is important for the webmaster to preserve the quality of the image as much as possible.

Removing unnecessary metadata (unnecessary information about the image)

Digital images contain a lot of data that only clutters up the pages of a website. Various information about the camera used, the properties of the image, etc. should be removed if such information is not important to users.

Correct scaling of a drawing/photograph on a web page

This image optimization criterion assumes that the original size parameters of the photo uploaded to the hosting should match the size of the image displayed on the page. For example, an image with the original dimensions of 1800×1200 should be reduced to 600×400 before uploading in order to display it on the web page in a reduced form.

Optimal image format

Vector format of the drawing is mainly used for website pages. In this case, image quality is not affected by such factors as resolution and scaling. JPEG and PNG can be used as traditional formats, but only in a compressed version.

Color

If the design and theme of the Internet resource do not imply the presence of bright and saturated colors in the images, then the color depth should be reduced to 256.
