Placeholder Image Generator
Generate a placeholder image of a given size for mockups and layout.
A placeholder of the right size lets you check a layout before real images are ready — with correct proportions and dimensions labeled right on the image, so you can orient yourself in the mockup.
How to use it
- Enter a width and height in pixels and a placeholder image is generated instantly with its dimensions labeled.
- Optionally set the background and text color to match the mockup's theme.
- Download the finished image or copy a link to use directly in a src attribute.
Common uses
- Laying out a page before real photos or illustrations arrive from a designer.
- Testing a responsive image grid with various aspect ratios and sizes.
- Demoing a prototype to a client with clear dimensions instead of empty boxes.
Things to keep in mind
SVG placeholders weigh just a handful of bytes regardless of the size you set — the format choice affects how much real weight they add to a page during development.
A placeholder is meant purely for temporary use in development — it must be swapped for a real image before launch.

Frequently asked questions
How do I control the image's size and appearance?
You set the width and height in pixels plus the background and text colors; if you don't type custom text, the tool defaults to showing the dimensions themselves, like 600x400.
What's this tool useful for?
It's meant for mockups and layout prototyping — dropping in a placeholder image lets you check spacing, aspect ratios and design before the real images are ready.
Can I use the image without downloading a file?
Yes, besides downloading you can copy the image as a Data URI and paste it directly into your HTML or CSS.
What's the difference between an SVG and a PNG placeholder?
An SVG placeholder is vector-based, so it scales without any loss of quality and usually weighs just a few kilobytes regardless of size, while PNG is a raster format whose weight grows with the image size — which better simulates how a real photo would behave when testing page performance.
Does a placeholder's size actually affect page load speed during development?
SVG placeholders barely affect speed at all, since they weigh just a handful of bytes regardless of the dimensions you set, while large raster placeholders can add noticeable weight to a page — so for performance testing, pick a format close to the eventual real image.
