⚙️ How It Works
Set width, height, colors, and optional label. The tool renders a live preview and lets you copy a Data URI, HTML <img> tag, or download the image in your chosen format.
❓ Frequently Asked Questions
What formats can I export?
You can download placeholders as SVG, PNG, or JPG. SVG is vector-based, while PNG and JPG are rasterized versions generated from canvas.
What is a Data URI and why use it?
A Data URI embeds the image directly in your HTML or CSS, eliminating external requests. This is useful for prototyping, emails, or lightweight UI mockups.
Can I customize the placeholder text?
Yes. You can override the default dimensions label with any custom text, along with background and text colors.
Does the Placeholder Image Generator work offline?
Yes, the Placeholder Image Generator is fully functional offline. Because this tool runs entirely in your browser, no data is ever uploaded to external servers. Once the page is loaded, you can seamlessly continue using it without an active internet connection. You can also install Knicknaks as a Progressive Web App (PWA) for native-like offline access.
