Slow pages lose visitors, and on most small websites the biggest cause is not code. It is photos straight from a phone camera, uploaded at full size.
Match the image to its slot
If a picture is shown 800 pixels wide, uploading it at 4000 pixels wastes bandwidth. Resize it first with the Image Resizer to about the largest size it will ever be displayed.
Choose a lighter format
Photos belong in JPG or WebP, and flat graphics in PNG. Compress each one and check that it still looks clean on a phone screen.
Name and describe them
Use a clear file name like red-leather-wallet.jpg instead of IMG_2041.jpg, and add a short alt text. It helps search engines understand the picture and helps visitors who use screen readers.
Free, no signup, and your files never leave your device.

How big should a website image be in KB?
Aim for under 200 KB for normal pictures and well under 100 KB for small ones, though it depends on the page.
Does image size affect Google ranking?
Indirectly. Faster pages give a better experience, and speed is one of many things Google looks at.
Also useful: WebP to JPG.
