Create Custom Dummy Images
When developing websites, drafting wireframes, or building UI prototypes, you often need images of specific dimensions before the final assets are ready. Our Image Placeholder Generator creates these dummy images instantly.
Unlike traditional placeholder services (like Placehold.it or DummyImage) that require network requests every time the page loads, this tool generates the actual image file or a Base64 SVG string directly inside your browser. This means zero HTTP request latency, offline compatibility, and complete privacy for your internal mocks.
Frequently Asked Questions
Why use an SVG Data URI instead of PNG?
An SVG Data URI is just a string of text representing the vector shapes. For a simple rectangle with text, an SVG string is dramatically smaller (often under 200 bytes) than a binary PNG image (which can be several kilobytes). This makes your prototypes load instantly and keeps your code repositories clean of temp image files.
How do I use the Data URI?
Copy the string generated above and paste it directly into your HTML:
<img src="data:image/svg+xml;base64,PHN2ZyB4b..." alt="Placeholder"/>
