Custom Placeholder Image Generator for Web Development and Mockups
Placeholder images are a fundamental tool in web development and UI design workflows. During development, real content is often unavailable — product photos haven't been shot, user avatars don't exist, article thumbnails aren't ready. Without placeholder images, layouts break, spacing looks wrong, and visual hierarchy is impossible to evaluate. Developers need a quick way to generate correctly sized placeholder images that accurately represent the dimensions and aspect ratios of the actual content they'll eventually replace.
Our placeholder image generator creates PNG images at any dimensions you specify — from 16×16 pixel icons to 2560×1440 pixel hero banners — in milliseconds, directly in your browser. Each generated image displays its dimensions as text by default (160×90, 1920×1080, etc.) so you can immediately identify placeholder sizes in a layout. Custom labels, colors, and font sizes let you create more descriptive placeholders that communicate content intent.
The generator supports batch production of multiple sizes, making it easy to generate a complete set of responsive image placeholders — thumbnail, medium, large, full-width — that match your CSS breakpoints. All output is PNG format, compatible with every image-accepting context: HTML img tags, CSS background-image, marketing email templates, Figma component libraries, and presentation slides.
Visual Placeholder Specifications for Design-to-Dev Handoff
Beyond simple dimension displays, the generator supports custom background colors, text overlays, and labels that communicate placeholder purpose — not just size. Label your placeholders with content type ('Product Photo', 'User Avatar', 'Hero Image') or content status ('Pending', 'Client Providing'), and you instantly create a meaningful skeleton for your designs. Your teammates and clients see the correct proportions and understand what each placeholder represents, eliminating confusion during review. Export to PNG for use in design files, or generate data URL inline images for embedding directly in HTML prototypes without external dependencies.
Web Layout Development and Wireframing
Fill image slots in your HTML templates during development with correctly sized placeholders that maintain layout proportions without needing real content assets.
Email Template Mockups
Generate placeholder images sized to email column widths (e.g., 600×400, 300×200) to mock up marketing email layouts before actual imagery is ready.
Responsive Design Testing
Generate a complete set of images at different breakpoint sizes (xs, sm, md, lg, xl) to test responsive layout behavior with correctly proportioned content at each viewport width.
- 1
Enter Width and Height
Type the desired width and height in pixels. Common presets (16:9, 4:3, 1:1, 3:2) are also available as quick-select buttons to avoid memorizing dimension numbers for standard aspect ratios.
- 2
Customize Color and Label
Choose a background color using the color picker or enter a HEX code. The default gray (#CCCCCC) works for most mockups. Optionally customize the label text — by default it shows the dimensions (800×600).
- 3
Preview and Adjust
A live preview of the generated placeholder appears immediately. Adjust font size, text color, and label position to ensure the text is legible at the target display size.

Download or Copy the Data URL
Click Download PNG to save the image, or click Copy Data URL to get a base64-encoded inline image URL you can use directly in HTML src attributes without needing a separate image file.
Any Dimension — From Favicon to Ultra-Wide Banner
Generate placeholder images from 1×1 to 9999×9999 pixels. Common size presets for icons, thumbnails, social media images, email headers, and hero banners are available as one-click options.
Custom Background Color and Text
Specify background and text colors with a visual color picker or HEX input. Labels default to dimension text but accept any custom string for content-type annotation.
Data URL Output for Inline HTML Embedding
Copy as a base64 data URL to embed the placeholder directly in HTML without needing an external file or network request — ideal for self-contained prototypes and email templates.
Batch Size Generation
Generate multiple placeholder images at different dimensions in one session, downloading each individually or as a ZIP archive for rapid design mockup population.
