Do I need to reduce the image size to the optimal size for the site page?

Question

css

Is it necessary to reduce the image to the optimal size for the site page if the site system displays an automatically reduced copy on the page, keeping the original?

Answer 1

If the preview is done on the fly, then of course it is necessary. If it is created at boot and stored as a separate file or lies in a perpetual cache, then it is not necessary. However, it is worth thinking about the total volume. When working with backups, it can backfire.

Answer 2

Why do you need to reduce the image if it is automatically cut anyway? Or I did not understand something!?

Answer 3

No need. It is necessary to configure the optimizer on the CMS side.

Answer 4

There is absolutely no need
