What is image placeholder

An image placeholder is a temporary image used while a final photo, graphic, or product asset is not ready. It keeps layouts stable, helps designers and developers test image sizes, and makes mockups easier to review.

With an image placeholder URL, you can set the width, height, color, and format directly in the link. That makes it useful for websites, apps, documentation, test data, and quick frontend prototypes.

How to insert an image placeholder in your project

Copy an image placeholder URL from the generator and use it anywhere an image source is accepted. For HTML, paste it into an img tag. For CSS, use it as a background image. For Markdown, place it in standard image syntax.

<img src="https://image-placeholder.net/img/600x400.png" alt="image placeholder">

Documentation

The URL rules are short, stable, and readable. The current API supports custom size, format, color, and Retina output.

Size

Use widthxheight for dimensions. Omit height to generate a square image.

/img/600x400
/img/400

Format

SVG is the default format. Add an extension for PNG, JPG, or JPEG output.

/img/600x400.png
/img/600x400.jpg
/img/600x400.jpeg

Colour

Background and foreground colors are passed together. Use hex values, CSS color names, or transparent.

/img/600x400/000000/ffffff
/img/600x400/transparent/111827

Retina

Add @2x or @3x after the size for high-density assets.

/img/600x400@2x.png
/img/600x400@3x.png
/img/600x400@2x.jpg

Examples

Combine size, color, format, and Retina scale to generate common image placeholder.

/img/600x400/FF0000/FFFFFF.png
/img/600x400/transparent/000000.jpg
