Lean site checker
Two free tools to make your site lighter without lowering its quality. Nothing is kept or sold.
1. Check a page
Paste the address of a public page. The tool reads the page and its files, then gives you fixes to copy and paste.
No made-up CO₂ or water figures: only real weight is measured. For an estimate, see the Sustainable Web Design model via CO2.js (it is an estimate). Green hosting: Green Web Foundation.
2. Make images lighter
Your images are converted on your phone or computer: they are never uploaded. Same pixel size. If the result is not lighter, the original is kept.
