SVG Placeholder Generator

Create completely offline, zero-latency placeholder images. Export them directly as Data URIs for immediate use in your HTML without needing external API requests.

Why use SVG Placeholders?

When prototyping layouts, developers frequently use external API services (like placehold.co or via.placeholder.com). However, these have significant drawbacks:

  • They require network requests which slow down your local development or staging environment.
  • They can go offline or be blocked by strict firewalls.
  • They load raster formats (PNG/JPG) which look blurry on high-DPI screens.

By using an inline SVG Data URI generated by this tool, your placeholders will render instantly, scale infinitely without blurring, and work completely offline.

Generate Ultra-Fast Placeholders

When building a website wireframe or designing a UI mockup, you rarely have the final photography ready. You need placeholder images to establish the layout. Our SVG Placeholder Generator allows you to instantly create lightweight, customizable dummy images without relying on slow external image APIs.

Why SVG Placeholders Are Superior

Historically, developers used services like `placekitten.com` or `via.placeholder.com` to inject temporary JPEGs into their code. SVG is a far better solution:

Frequently Asked Questions

How do I embed the placeholder in my code?

You can either download the `.svg` file and link to it like a normal image (``), or you can copy the raw Data URI string we provide and paste it directly into the `src` attribute.

Does the text automatically center?

Yes. The generated SVG code uses the `text-anchor="middle"` property and exact X/Y coordinate percentages to ensure the dimension text is always perfectly centered, regardless of the box size.

Is this tool completely free?

Yes. Unlike some placeholder APIs that rate-limit you or inject their own branding into the image, this generates pure, unbranded XML code locally on your machine.
