I built a simple web tool that splits images into grid layouts (2×2, 3×3, 4×4, or custom sizes up to 20×20).

Everything runs client-side using HTML5 Canvas, so images never leave the browser. No server uploads, no accounts, no tracking.

I originally made it for creating Instagram grid posts, but it's also useful for puzzles, multi-panel prints, and splitting large images for tiled printing.

Would appreciate any feedback on the UX or feature suggestions.
