GUIDE
How to Compress Images for a Website
Practical image optimization guidance for websites.
Images can be a major part of a webpage's transfer size. Good web optimization balances dimensions, format and visual quality.
Match dimensions to display size
Do not send a huge original when the page displays a much smaller image.
Choose a web-friendly format
WebP is widely supported by modern browsers and can be useful for photographs and graphics. JPG remains a practical compatibility choice.
Preview before publishing
Check both visual quality and file size. An image that looks excellent but is unnecessarily large can still slow a page.
