Generate placeholder images with custom dimensions, colors, and text. Download as PNG for your designs and mockups.
Placeholder images are essential during web development and design prototyping when real images aren't yet available. Instead of leaving empty img tags or broken layouts, developers use placeholder images to visualize how a page will look with content. This generator creates placeholder images directly in your browser without any server calls — you get a canvas-rendered image with your chosen dimensions, colors, and custom text. It's useful for wireframes, mockups, email templates, CMS demos, and any situation where you need a stand-in image immediately. Generated images can be used as data URLs in HTML, saved as PNG files, or referenced locally in your project.
Images are generated as PNG files using the browser's Canvas API. PNG provides lossless quality and supports transparent backgrounds, making it ideal for UI mockups.
These are placeholders — they're perfect for development and demos, but for production you'd replace them with real photography or graphics. However, simple colored squares with text labels can work in some UI contexts.
Very large images (over 4000×4000px) may be slow to generate or fail on some devices due to canvas memory limits. For most prototyping needs, standard sizes work fine.
You can save the image and link to it, or use the data URL format directly in your img src attribute: <img src="data:image/png;base64,...">
Not in this tool — generate one size at a time. For batch generation, consider using placeholder services like via.placeholder.com in your markup during development.
