Can I compare the desktop and mobile versions of a page?
Yes. The Desktop vs Mobile button in Capture by RATdeck Pro captures the current page at a desktop width and at a phone width, then shows both side by side in the comparison view. It is a quick way to check a responsive layout, a landing page or a client site before launch.
How do share links work?
Capture by RATdeck Pro can create a share link for an annotated screenshot or a before/after comparison. Capture asks for your consent before anything is uploaded. Anyone with the link can view the image until it expires after seven days or you revoke it. Normal capture and editing never upload anything.
