Placeholder Image Generator

A placeholder image generator creates a plain, sized rectangle, usually labeled with its own dimensions, to stand in for real artwork that is not ready yet. This tool draws that placeholder on an HTML canvas inside your browser and exports it as a PNG. You set the width and height in pixels, choose a background color and a text color, and type any label you like; by default the label is the dimensions themselves, such as 800x600, which makes it obvious at a glance how big the slot is. Unlike hosted services such as placehold.it or via.placeholder.com, nothing here depends on a remote server. That means no broken images when a third-party endpoint is rate-limited or goes offline, no tracking pixels, no attribution, and no watermark baked into the file. It also means the generated PNG is a static file rather than a live URL, so if you specifically need a hotlinkable address that resizes on demand you would still reach for a hosted service, but for a fixed asset you drop into a design this is faster and fully private. The output is a flat, single-layer PNG with a solid background, which is exactly what wireframes and mockups call for. It pastes cleanly into Figma, Sketch, Photoshop, a slide deck, or a local dev build, and because the colors and text are yours, you can match a client's brand or color-code different image regions in a layout. You can generate sizes up to 4000x4000 pixels, though very large dimensions may briefly tax older browsers. Use it to fill empty image slots in a prototype, stub thumbnails during development, or swap in a tidy rectangle when a real asset is still missing during a presentation.
