You are building a website mockup, and everything is coming together. The typography is perfect, the spacing is balanced, and the layout is clean. But those empty gray boxes where images will eventually go make the design feel incomplete. You need placeholder images that look professional but do not distract from the overall concept.
This placeholder image generator is designed to create dummy images that fit seamlessly into your wireframes, mockups, and prototypes. Choose exact dimensions, pick background and text colors, add custom labels, and download in PNG, JPEG, or WebP format. All images are generated locally in your browser, keeping your work private and secure.
What People Use This For
Here are some real ways people use this tool.
Prototyping Web Layouts
A designer creates a website mockup and needs placeholder images to show where photos or graphics will go. They generate custom-sized images with labels like "Hero Image" or "Product Photo."
Filling Wireframes and Mockups
A developer builds a wireframe and needs realistic image blocks to test spacing and layout before real assets are ready for integration.
Generating Test Images for Development
A programmer needs images of specific dimensions to test image processing pipelines, responsive layouts, or lazy loading behavior.
Creating Banner and Social Media Templates
A content creator designs social media graphics and uses placeholder images to test different sizes before adding final content.
Demonstrating Design Concepts
A freelancer presents a design to a client and uses placeholder images with labels to show where final images will go, making the mockup easier to understand.
Testing Responsive Design
A developer generates images at different sizes to test how a website adapts across desktop, tablet, and mobile viewports.
Did you know? Placeholder images have been a staple of design and development since the early days of web design. They allow designers and developers to focus on layout, spacing, and user experience without waiting for final photography or graphics. Tools like this one have evolved from simple gray boxes to fully customizable, professional-looking placeholders that can match brand colors and include descriptive text.
How the Placeholder Image Generator Works

Our tool uses your browser's Canvas API to generate an image with your chosen dimensions, colors, and label text. As you change settings, the live preview updates instantly. When you click Download, the image is saved directly to your device.
All generation happens locally. No images are uploaded to any server. Your work stays private.
Settings and Options
Options to customize your placeholder image.
📏 Width and Height
Enter pixel dimensions to create images of any size. Common dimensions like 800×600, 1920×1080, and 400×400 work perfectly.
🎨 Background and Text Colors
Use the color pickers to set your main background color and label text color. Hex codes are displayed for easy reference.
🏷️ Label Text
Enter custom text like "Hero Image" or "Banner." Leave empty to automatically show dimensions (e.g., "800 x 600") on the image.
📁 Format
Choose between PNG (lossless quality), JPEG (compressed, smaller file size), or WebP (modern web format with excellent balance).
Generation Modes
Four modes to match your design needs.
🎨 Custom
Precise dimensions with solid background and text color. The main mode for creating exactly the placeholder you need.
📊 Presets
Ready-made sizes for web, social media, and print. Quick access to common dimensions like Instagram posts, Stories, Twitter headers, and more.
🌈 Gradient
Smooth two-color gradients in any direction. Adds visual interest to mockups and makes placeholders more engaging.
🔲 Pattern
Grid, dots, diagonal, and checkerboard backgrounds. Useful for adding texture to wireframes and testing visual hierarchy.
Pro tips for effective placeholder images: Use custom text labels for clarity. Instead of showing dimensions, add a label like "Hero" or "Product Image." This makes mockups easier to understand for clients and stakeholders. Match colors to your brand. Use your brand colors for background and text to create mockups that feel closer to the final design. Choose format based on use. PNG is best for crisp text and sharp edges. JPEG offers smaller file sizes for web testing. WebP is modern and efficient for responsive designs. Use live preview to fine-tune. The preview updates as you adjust settings. No need to click generate. See changes instantly. Experiment with presets for common sizes. Need a standard social media size? Check the Presets mode for ready-made dimensions.
