SVG vs PNG Placeholders

Using Data URIs

Data URIs let you embed placeholder images directly in HTML or CSS without separate files. Great for prototyping — just paste the data URI as the src attribute or background-image value.

Frequently Asked Questions

How do I generate an SVG placeholder image?

Set the width, height, background color, and display text. The tool generates an SVG placeholder you can copy as a data URI, embed inline, or download — perfect for prototyping before real images are ready.

What are SVG placeholder images used for?

Placeholders are temporary stand-ins during development showing the intended dimensions of an image slot. They display size labels, making wireframing and layout testing faster without needing actual content images.

How do I add an SVG placeholder to my HTML?

Use <img src="placeholder.svg" width="300" height="200" alt="placeholder"> or embed SVG inline. The tool also generates data URIs for use directly in src attributes without hosting a separate file.

Can I customize the SVG placeholder text and colors?

Yes — set background color, text color, font size, and the label text. Common choices include showing dimensions like "300×200", a descriptive label, or leaving it blank for a solid color block.

What is a data URI SVG?

A data URI embeds the SVG directly in the HTML as a URL-encoded string, so no separate file is needed. Example: <img src="data:image/svg+xml,...">. Great for small inline placeholders in prototypes.
