How it works

Submit a public page, review the result, and compare the original and proposed designs. A preview is a design proposal. Review its content, links, layout and accessibility before implementing it on your website.

Start with one public page

You can enter a full HTTP(S) URL or a domain such as example.com. Use a page you own or have permission to submit. Login pages, private addresses and pages that block capture are not supported.

Read the result honestly

An alternative direction is not a verified improvement. Sometimes the original is retained. Change explanations distinguish measurements from design targets whose effect has not been measured. Review readability, brand fit and your main customer action yourself.

Apply with your implementer

Download the handoff guide from a completed result. It contains the permitted preview images and a review plan, not source code for your website. Choose the changes to implement, try them on a copy of your site, and test content, links, forms, mobile layout and keyboard access before publishing.

Return or retry

Use Recent previews in the same browser within the access period. If a connection fails, retry from the current screen. If access has expired, submit the source URL again. Clearing cookies or switching browsers can remove access to previous results.
