  • Use PNG when you need a transparent background.
  • Add descriptive file names and alt text when you upload images to your site for better image SEO.

Worked Example

Example: a 5 MB photo from a phone is uploaded to a blog post and slows the page down. Resizing it to 1200 px wide and converting it to WEBP can reduce it to well under 200 KB while it still looks sharp on screen, which makes the page load noticeably faster.
