Why Use Our Dummy Image Generator?

Any Size, Instantly

Enter any width and height from 1 px to 4000 px and the canvas updates live. Quick-preset buttons cover the most common sizes, FHD, HD, square post, social banner, web thumbnail, so you can jump to a standard resolution in one click.

Custom Colors & Text

Pick any background and text color with the native color pickers, or hit the Random button to generate a high-contrast color pair automatically. Add custom label text or leave it empty to display the dimensions, great for wireframes and mockups.

PNG, JPG & WEBP Output

Download your placeholder image as PNG for lossless quality, JPG for smaller file size, or WEBP for modern browsers. All formats are generated directly from the HTML canvas using the native browser API, no server processing required.

No Upload, No Server

Everything happens inside your browser using the HTML5 Canvas API. No image is ever uploaded to a server, no account is needed, and no data leaves your device. The download button triggers a local file save directly from the canvas.

Frequently Asked Questions

Common questions about generating placeholder and dummy images.

What is a dummy image and why do developers use them?
A dummy image is a placeholder image used during design or development before real content is available. Developers use them to visualize layouts, test responsive breakpoints, and fill image slots in mockups or prototypes without needing actual photographs or graphics.
What is the maximum image size I can generate?
The generator supports widths and heights from 1 px up to 4000 px. Very large canvases (such as 4000 × 4000) require significant browser memory and may be slow on older devices. For most web and design purposes, sizes up to 1920 × 1080 are generated instantly.
Can I use the generated images in commercial projects?
Yes. The images are generated entirely by your browser from settings you specify, there is no third-party content involved. The output is a solid-color canvas with optional text. You own the result and can use it in any project, commercial or otherwise.
What does the Copy Data URI button do?
The Copy Data URI button copies a base64-encoded representation of the canvas image to your clipboard. This data URI can be pasted directly into an HTML img src attribute or a CSS background-image property and will display the image without needing a separate file.
