How to optimize images?

Question

What are the available options to optimizing images for web?

Answer 1

I read in a another tutorial to form a ratina image for higher resolution display define width and height half the original size

Answer 2

.jpg files that are compressed, renamed with keywords, served at scale and alt text with keywords.

Answer 3

Increase the size of a photograph to boost its resolution, then make sure it has the best pixel density. Although the image is larger, it may appear less sharp than the original. You'll notice a difference in sharpness as you increase the size of an image.

PPI stands for Pixels Per Inch and is a measurement of a digital image's printing size. The higher the pixel density per inch, the better the printing quality; yet, 300 PPI is adequate for high-quality printing. At 150 PPI, 300x300 pixels are printed. An iCreativeSOL poster of 22 inches is still too small.
