Image Placeholder Guide
Enter width and height in pixels. Use the presets for common web sizes, or enter exact dimensions for your specific layout — hero images, card thumbnails, profile photos, or ad banners.
Choose background and text colors to differentiate content areas in wireframes. Add a label like "Hero Image" or "Product Photo" to make the placeholder self-documenting in your mockup.
Download the PNG to use in Figma, Sketch, or code mockups. Or use the generated URL in your HTML during development as a src attribute until real images are available.

Why Use Placeholder Images?
Placeholder images serve as temporary stand-ins during design and development workflows. In wireframing and prototyping, they establish visual weight and layout proportions without requiring real photography — helping stakeholders review layout decisions before content is ready. In front-end development, placeholder images let developers build and test layout, responsive breakpoints, and image handling logic (lazy loading, aspect-ratio containers, error states) before the actual assets are delivered. Using correctly-sized placeholders from the start also prevents layout shift (CLS), a Core Web Vitals metric, because the browser reserves the exact space the final image will occupy.
