This placeholder image generator creates clean SVG dummy images with a custom width, height, background color, and label text — perfect for filling image slots in wireframes, mockups, and prototypes before real assets are ready. It's a staple tool for UI/UX designers building layout mockups, developers scaffolding a component library, and content teams drafting a page structure without waiting on final photography. Set your dimensions, pick a background color, add optional label text like the pixel size or a placeholder name, and the SVG renders instantly with a download link ready to drop into your project. Because the output is SVG rather than a raster image, it stays crisp at any display size and keeps file sizes tiny, which is ideal for placeholder content that might appear in many places across a prototype. Everything is generated client-side with no external image-hosting dependency, so you're not relying on a third-party placeholder service that could go offline or rate-limit your requests. There's no signup and no limit on how many placeholder images you generate. Scroll down to set your dimensions and generate your placeholder image.

Frequently asked questions
Why use an SVG placeholder instead of a PNG?
SVG placeholders stay sharp at any size and have a much smaller file size than an equivalent raster PNG, which is ideal for prototypes with many placeholder slots.
Can I add custom text to the placeholder image?
Yes, you can label the placeholder with any text, such as the image dimensions or a descriptive name for the intended content.
Is this reliable to use instead of an external placeholder image service?
Yes, since the SVG is generated and downloaded locally, it doesn't depend on an external service staying online, unlike hotlinked placeholder URLs.
Can I set a specific aspect ratio for my placeholder?
Yes, entering exact width and height values lets you match any aspect ratio your layout requires.
Does this tool work for mobile wireframes too?
Yes, you can set any dimensions, including narrow mobile-sized placeholders for responsive design mockups.
Is my design data uploaded anywhere?
No, the placeholder image is generated and rendered entirely within your browser.
Can I change the placeholder's background color?
Yes, you can set any custom background color, along with a matching or contrasting text color for the label.
