SVG to CSS Data URI Converter
Convert SVG code to CSS background-image data URIs for use in stylesheets. Data URIs allow you to embed SVG graphics directly in your CSS without separate HTTP requests, improving performance. This is especially useful for SVG icons, patterns, and simple illustrations that you want to use as CSS backgrounds.
Frequently Asked Questions
Why use SVG as CSS background?
Using SVG as a CSS background with data URIs eliminates extra HTTP requests, making your site faster. It also allows easy color customization through CSS variables and keeps your SVG assets in your stylesheet. This is ideal for icons, patterns, separators, and decorative elements.
What is a data URI?
A data URI is a way to embed small files directly in a document as a base64 or URL-encoded string. For SVG, the data URI looks like: url("data:image/svg+xml,..."). This allows the browser to display the image without making an additional HTTP request to load a separate file.
Should I use base64 or URL encoding?
URL encoding (percent-encoding) is generally more efficient than base64 for SVG because SVG is XML text. Base64 increases file size by about 33%, while URL encoding typically results in a smaller output. However, some older browsers handle base64 SVGs better. URL encoding is recommended for modern projects.
Can I use CSS custom properties with SVG?
When SVG is embedded as a data URI, CSS custom properties (variables) cannot directly change SVG fill colors because the SVG is treated as an external image. To use dynamic colors, consider using inline SVG in HTML or setting SVG colors before converting to a data URI.
What SVG elements work as CSS backgrounds?
All valid SVG elements work as CSS backgrounds: shapes (rect, circle, path), text, groups (g), defs with symbols, gradients, filters, and patterns. Ensure your SVG has a viewBox attribute for proper scaling. Avoid external references (images, fonts) as they may not load when embedded as a data URI.
