Redesign Image Tools Site Layout

I’m ready to give https://image-tools-sandy-alpha.vercel.app/ a fresh, more intuitive look. My main priority is the overall layout: I want to move to a clean, responsive grid-based structure that instantly tells visitors where to look and how to act.

Key considerations
• The grid should adapt gracefully from desktop to mobile without breaking visual rhythm.
• An engaging, easy-to-browse image gallery is essential—this will sit at the heart of the new grid. Think smooth hover states, lightbox or modal viewing, and lazy-loading for speed.
• All current functionality must remain intact; this is a visual overhaul, not a rebuild of the tool logic.

I’ll provide prompt feedback on wireframes and high-fidelity mock-ups. Final deliverable is a polished Figma (or similar) file plus any supporting assets so my developer can implement immediately.
