How to get better results from this tool.
Use these tips to keep placeholders useful without letting temporary content become permanent.
Pick realistic dimensions
Use the same aspect ratio as the final image so cards, hero sections, and social previews do not shift later.
Use SVG for fast mockups
SVG placeholders are lightweight, scalable, and easy to paste into static prototypes or design documentation.
Test responsive behavior
Preview narrow and wide layouts to make sure image placeholders do not crop, overflow, or create awkward spacing.
Use placeholder images with realistic dimensions.
Good image placeholders help you test cards, heroes, social previews, and responsive layouts before final assets are ready.
Hero and Open Graph images
Use wide ratios such as 1200 × 628 for social previews and large landing page mockups when you need realistic visual weight.
Cards and thumbnails
Keep placeholder aspect ratios close to the final asset so the grid spacing, cropping, and responsive behavior stay accurate.
SVG vs PNG
Copy SVG when you want lightweight, editable markup. Download PNG when another tool requires a raster image.
