About This Tool
The Image Placeholder Generator builds lightweight vector and raster dummy images for prototypes, wireframes, component mockups, and unit tests.
Instead of relying on slow external image services that break offline or introduce third-party trackers, all placeholders are rendered instantly inside your browser as SVG data URIs or downloadable PNG files.
Key Features
- Custom dimensions and presets: Input any width and height in pixels or select standard sizes for Open Graph, HD video, and ad banners.
- Automatic text scaling: Font sizing automatically scales to fit your dimensions, or you can specify exact pixel values.
- Copy-ready Data URIs: Paste inline data:image/svg+xml strings directly into HTML img src or CSS background properties without extra network requests.
- Instant SVG and PNG download: Save placeholders as crisp SVG vectors or standard raster PNG files for direct use in image editors.
Frequently Asked Questions
How do I use the Data URI in HTML?
Copy the Data URI and paste it directly into your image tag: <img src="data:image/svg+xml,..." alt="Placeholder" />. It renders instantly without an HTTP request.
What is the default label if I leave Custom Text blank?
When the text field is empty, the placeholder displays its exact pixel dimensions (for example, "800 x 600").
Can I use this for Open Graph social card testing?
Yes. Choose the 1200 x 630 preset to generate standard Open Graph image dimensions for testing social preview layouts.
Are placeholders generated locally?
Yes. Generation occurs entirely in your browser memory without contacting external APIs or servers.
