The Dummy Image Generator is a free online tool for web designers and developers that creates custom placeholder images in any specified dimensions and colors. Placeholder images are used during the design and development phase to represent where actual images will appear — maintaining layout proportions without needing final assets.

Rather than using external services or hunting for images, this tool generates placeholder images on demand in PNG, JPG or GIF format, displayed with the image dimensions as text overlay for easy reference.

How to Generate Placeholder Images

• Enter the desired width and height in pixels (e.g. 800x600)
• Choose a background color and text color
• Optionally add custom text (e.g. "Hero Image", "Product Photo")
• Choose the image format (PNG, JPG)
• Click Generate — download or copy the image URL

Use Cases

• Fill image slots in HTML/CSS wireframes and prototypes
• Placeholder for product photos in an e-commerce MVP
• Test responsive image behavior before final assets arrive
• Create consistent-size thumbnails for layout testing

Embed Direct URLs

Generated images can be embedded directly in HTML using the tool's image URL — updating the URL parameters changes size or color instantly without downloading a file. Free, no login required.
