CSS Layout Testing Images
Generate images at extreme aspect ratios to stress-test responsive CSS layouts.
Preset sizes
Color themes
💡 For HTML mockups: use the “Copy as data URL” option and paste into <img src="..."> for inline placeholders. For Figma / Sketch designs, download the PNG and drag in.
CSS Testing tips
For testing image grids: generate images of varied aspect ratios (square, portrait, wide). See if your CSS handles them.
For testing very tall or wide images: use the custom dimensions to make absurd aspects like 100×1000 or 2000×100.
Enable "Show diagonals" to visually verify alignment and crops at different sizes.
