Image Placeholder Generator
Generate placeholder images for wireframes, prototypes, or empty CMS slots. Pick any dimensions, any background color, any text overlay. Output as SVG (resolution-independent, tiny file) or PNG (compatible with every renderer). No upload — everything runs in your browser.
How to use the Image Placeholder Generator
Set the dimensions, colors, and text. The preview updates instantly. Pick the output format: SVG for any size with zero file-size overhead and crisp text rendering at every zoom level; PNG for legacy compatibility (older email clients, some CMS); WebP for the smallest raster file size.
Use the Copy data URI button to get an inline src="data:image/..." string ready to drop into your HTML.
About Image Placeholder Generator
Placeholder images are essential during design: a wireframe that shows where images will go is easier to communicate than empty boxes, and a CMS prototype that gets test images right-sized lets you build the layout properly. Online services like via.placeholder.com and unsplash.it work but require network calls (slow, and a privacy concern for sensitive prototypes). Generating placeholders locally in your browser is faster and keeps the workflow self-contained.
The SVG output is especially nice for design tools: a single SVG file scales to any size without pixelation, weighs a few hundred bytes regardless of the dimensions you requested, and the text renders crisply at every zoom level. PNG and WebP are there for tools that don’t accept SVG (some older email clients, certain CMS image fields with strict MIME validation).
Common use cases
- Wireframes and prototypes — fill image slots with size-labeled placeholders.
- Empty CMS state — fallback image when a content editor hasn’t uploaded yet.
- Component library demos — show
<Image>components without real assets. - Email template testing — mock hero images at exact dimensions.
