About Placeholder Image Generator – SVG & PNG, Offline
A placeholder image is a temporary graphic that stands in for real artwork while you build a layout — sized exactly to the slot it fills and labelled with its dimensions. This placeholder image generator creates them on demand: pick a width and height, choose background and foreground colors, add a label, and you get a crisp dummy image to drop straight into a mockup.
Most placeholder services fetch every image from a remote URL, which means a network round-trip for each one and your layout details leaking offsite. This tool renders everything locally instead — the SVG markup is built in your browser and rasterized to PNG with the Canvas API, so nothing is fetched and nothing leaves your device.
Copy the SVG, grab a data-URI to inline, or download a PNG. It's a fast, fully offline alternative for filling out wireframes, testing responsive grids, and seeding image placeholders during development.

Frequently asked questions
What is a placeholder image?
A placeholder image is a stand-in graphic used while designing or developing a page, before the real image is ready. It is usually a solid color sized to the layout slot with its dimensions printed in the middle, so you can see exactly how the space fills out.
Is this a replacement for placeholder image services?
Yes. Services that serve images from a URL require a network request for every placeholder and route your sizing choices through a third party. This tool generates the same kind of image entirely in your browser — no requests, no tracking, and it works with the network unplugged.
Can I download a PNG instead of SVG?
Yes. The SVG is rendered to a canvas in your browser and exported as a PNG you can download. You can also copy the raw SVG markup or an inline data-URI if you prefer a vector that scales without blurring.
Why use SVG for placeholders?
SVG is tiny, resolution-independent, and stays sharp at any size, which makes it ideal for placeholders. When you need a raster file — for tools that expect PNG or JPEG — the canvas export gives you a PNG at the exact pixel dimensions you set.
