Image Weight Audit

Enter a URL and see what every image on your page actually weighs, which ones are worth fixing first, and what the biggest would weigh converted.

What it does

Weighs the images on a page, converts the biggest to AVIF and WebP, and shows you the smaller result. Fixes come back as a short list, biggest saving first.

How to use it

  1. Paste one page. A product or category page usually tells you more than the homepage.
  2. Work down the fix list from the top. Under about 500 KB in total, the rest is housekeeping.

Good to know

  • Animated GIFs get their own line, because the fix for them is a video file, not a new image format.
  • Images set in CSS or added by a script aren’t seen.
  • We treat the first image on the page as the one LCP times. That’s often right, not always.

Image weight is one part of Site Speed, and the Free Site Audit checks far more than images.
