What's the difference between the SVG markup and the data URI output?

The SVG markup is the raw ` ... ` XML, useful as a standalone `.svg` file, while the data URI wraps that same markup so it can be dropped directly into an `img src` or CSS `url()` without a separate file.

Is this placeholder safe to use in a production site?

It works fine as a genuine fallback image or an empty-state graphic, but it's built for mockups and prototyping, so treat it as a stand-in rather than a polished asset for a finished design.

Can I control the aspect ratio and size exactly?

Yes, width and height are set independently as plain numbers up to 4000px each, so you can match any aspect ratio a layout needs rather than picking from a fixed list of sizes.

Does generating a placeholder image send any data to a server?

No, the SVG string is assembled with plain JavaScript template concatenation in your browser tab, so nothing about the size, colors or text you choose is sent anywhere to produce the image.

A one-line dummy image for mockups and layouts

Instead of pulling a placeholder image from an external service that adds a network request and a dependency on that service staying up, this tool builds one as plain SVG markup: a colored rectangle with a centered label. It's meant for mocking up a layout, seeding a design file, or filling an `img` tag while real assets aren't ready. Because it's generated markup rather than a rendered raster file, the output is tiny and the whole thing runs as string concatenation in your browser.

How to use the SVG Placeholder Generator

Set a width and height in pixels, up to 4000px on either side.
Pick a background color and a text color using the color swatches.
Type custom text, or leave it blank to show the dimensions like '480×240' by default.
Copy the SVG markup to save it as a `.svg` file, or copy the data URI to paste straight into an `img src` or CSS `url()`.

There's no rendering step involved, so the output is a few hundred bytes of markup rather than a decoded and re-encoded image, and it scales to any display size without going blurry.

The label's font size is chosen automatically from the smaller of width and height when you leave the text field blank, so very small or very wide placeholders still get a readable label.
