How to Make a Placeholder Image Online
A placeholder image stands in for real artwork while you build a layout, mockup or wireframe — a neutral block at the right size with its dimensions labelled. This generator makes one instantly: set the width and height, pick your colours, add any label you like, and download a real PNG. Unlike placeholder services that need a live URL, this creates an actual file you can drop straight into your project, all in your browser.
Set the size
Choose a preset or type any width and height for your placeholder.
Style it
Pick background and text colours and add an optional label; the preview updates live.
Download
Save a real PNG file to drop into your mockup or code.
What to Use It For
Mockups & wireframes
Fill image slots in a design with correctly-sized blocks so the layout reads clearly.
Front-end testing
Drop in placeholders while building a page before the real images are ready.
Exact ad & OG sizes
Generate common sizes like 1200×630 for social cards or 300×250 for ad slots.
A real file, not a URL
Get a downloadable PNG instead of relying on a placeholder service that could go down.

How do I make a placeholder image for free?
Set the size, pick your colours and label, and press Download — you get a real PNG, free, no signup, no watermark.

Any dimensions up to 5000px per side. Handy presets cover common cases like 1200×630 social cards and 300×250 ad slots.
