Placeholder Image Generator — any size, fully local
The placeholder generator quickly creates dummy images at a given size for development, prototyping and layout. Enter width and height, pick a background, show W×H by default or custom text, and export a PNG. Shape Cat generates it in your browser with no external placeholder service.

Frequently asked questions
How is this different from placehold.co?
Those services fetch an image by URL over the network; this generates the PNG locally in your browser — works offline, lets you set color and text, and leaks no request.
What's the max size?
Up to 4000px per side, enough for almost any web or prototype placeholder need.
