Placeholder Image Generator
Generate a plain placeholder image at any dimensions, labelled with its size, for mockups and layout testing.
A stand-in while you build
When you are laying out a page or a design, you often need an image in a slot before the real one exists. A placeholder — a simple block of the exact dimensions, usually with the size written across it — fills that gap so you can see how the layout behaves without hunting for stock photos. It keeps the spacing honest and stops empty boxes from collapsing.
Set the width and height, and you get a clean rectangle at precisely that size, ready to drop into a mockup, a slide or a coded prototype.
Why the size label helps
Printing the dimensions onto the placeholder means that when you are staring at a busy mockup full of grey boxes, each one tells you exactly how big it is. It is a small thing that saves a lot of second-guessing about whether a slot is the size you intended.

Design with the right shapes
Placeholders let you build and test a layout before the real photography exists. Using correctly proportioned blocks matters more than it sounds — a design that looks balanced with square placeholders can fall apart when wide product shots arrive.
Labelling each placeholder with its dimensions is a small habit that saves confusion later, especially when handing designs to someone else to populate.
