Free Placeholder Image Generator
Generate placeholder images in SVG or PNG with custom size, colors, and text.
How It Works
Set width, height, background color, text color, and optional label text. The tool generates a placeholder image as a data URL using the HTML Canvas API — no external service is called. Preview the image in real-time, then download it as PNG or copy the data URL to use directly in your HTML or CSS.
When to Use It
- Building wireframes or prototypes that need placeholder images before final assets are ready.
- Testing responsive layouts with different image dimensions without downloading external placeholder services.
- Creating documentation or tutorials that need sample images with specific dimensions clearly labeled.
Frequently Asked Questions
Why not use placehold.co or similar services?
External placeholder services add a network dependency — if they go down, your images break. This tool generates images locally using Canvas, works offline, and never makes external requests. The data URLs are self-contained and will never break.
What image formats are supported?
Images are generated as PNG (lossless) through the Canvas API. The data URL can be used directly in img src attributes, CSS background-image properties, or downloaded as a PNG file for use in design tools.
Can I use custom fonts in the label?
The tool uses the system default sans-serif font for maximum compatibility. The label text (usually dimensions like "800x600") is rendered at a proportional size that scales with the image dimensions.
