Placeholder Image Generator

What is a Placeholder Image?

A placeholder image is a temporary graphic used in web design, app development, and wireframing. It acts as a stand-in for final images that are not yet available, ensuring that the layout structure and sizing of a page are maintained during the development process.

Using placeholders allows developers and designers to see how content will flow around images without having to source real photography or illustrations upfront.

Why use a Data URI?

This tool allows you to copy the generated image as a Data URI (a base64 encoded string representation of the image). You can paste this directly into your HTML's <img src="..."> attribute or CSS background-image: url(...).

• Fewer HTTP Requests: Data URIs are embedded directly in the code, so the browser doesn't need to make a separate network request to fetch the image.
• Offline Support: Because the image data is in the code, it works perfectly without an internet connection.
• No Broken Links: You don't have to worry about external image hosting services going down or deleting your placeholder images.

Client-Side Generation

Our Placeholder Image Generator runs entirely in your web browser using HTML5 Canvas API. No data is sent to a server. When you adjust the dimensions, colors, or text, the image is rendered locally on your device.

This ensures maximum privacy, rapid live previews, and the ability to use the tool even if you go offline after the page has loaded.
