About this tool

Paste your page HTML to check every <img> tag: missing alt text, missing width and height, missing modern formats, and below-fold images without lazy loading.

How to use

  1. 1Copy the full HTML source of the page you want to audit (view source, not just the body).
  2. 2Paste it into the input and review the five checks.
  3. 3Fix in order: add alt text to every image, add width and height to prevent layout shift, add loading="lazy" to images below the first one, and consider WebP/AVIF or srcset for smaller downloads.
