Blank Image Generator

Pick a width, height and a background color (or tick transparent), and download a brand-new blank image with no upload needed at all.

What is the Blank Image Generator?

Sometimes you don't need to edit a photo, you need a placeholder — a plain rectangle of a known size and color to drop into a mockup, test a layout, or use as a dummy asset before the real image is ready. This generator builds that image entirely from scratch on a canvas and lets you download it instantly as a PNG, with the option to make the background fully transparent instead of a solid color.

Common Use Cases

• Creating a placeholder image for a website mockup or wireframe at an exact pixel size
• Generating a solid-color background layer to build other graphics on top of
• Testing how a layout handles images of a specific width and height before real content exists

How to Use the Blank Image Generator

1. Enter the width and height you need, in pixels.
2. Pick a background color, or tick Transparent background to skip color entirely.
3. Check the live preview updates to the size and color you chose.
4. Click Download Blank Image to save the PNG.

Frequently Asked Questions

What's the largest size I can generate?

Up to 8000 by 8000 pixels, which covers everything from small icons to large print-ready placeholders.

What file format does it download as?

Always PNG, since PNG supports both solid colors and true transparency without any quality loss.

Can I pick an exact hex color?

Yes — click the color swatch to open your browser's native color picker, which accepts hex, RGB or a visual palette.

A dummy image generator is a small thing, but it saves you from hunting down a placeholder file or opening a full editor just to get one solid rectangle.
