Placeholder Image Generator
Create a plain placeholder image with its size labelled on it.
Leave the label blank to show the pixel dimensions.
What Is This Tool?
This tool draws a flat rectangle at the width and height you specify and writes the dimensions (or your own text) across the middle. It is handy for mocking up layouts, filling image slots in a template, or testing how a component handles a given aspect ratio.
How It Works
Set the Width and Height in pixels.
Pick background and text colours, and an optional label.
Choose the output format.

Frequently Asked Questions
Can I generate these by URL like placeholder services?
No — this is a local generator with a form, not an API. It has the advantage of working offline and never logging a request.
How big can the image be?
Very large sizes (several thousand pixels per side) work but use more memory. For layout mockups a few hundred pixels is plenty.
Why is my JPEG placeholder slightly fuzzy at the edges of the text?
JPEG compresses hard edges less cleanly. Use PNG for crisp text on flat colour.
Can I make a transparent placeholder?
Choose PNG or WebP and set the background to a colour you will key out later; true transparency output is not offered here — use Solid Color Image with an alpha workflow instead.
Is anything uploaded?
No, the image is drawn in your browser.
