What Is a SVG to CSS?

Inline SVG in CSS dodges an extra HTTP request — useful for small icons, patterns, and decorative graphics that appear on every page. The trick is the encoding: SVG contains characters (`#`, `<`, `>`, `"`) that need to be escaped to live inside a CSS `url()`. Base64 works but inflates the payload; URL-encoding the SVG keeps it smaller and gzips better than the equivalent Base64.

The converter does the URL-encoding correctly, escaping only the characters that actually need it. The output is a complete CSS declaration you can paste straight into a class — usually for a checkbox icon, a chevron, or a decorative pattern background.

Frequently Asked Questions

Why use SVG as CSS background?
Inline SVG in CSS avoids extra HTTP requests. Good for icons, patterns, small graphics. A single stylesheet contains everything.
Why URL-encode instead of Base64?
URL-encoded SVGs are typically 20-30% smaller than Base64 and gzip better. Browsers handle both, but URL-encoding wins on size.
Do I need to encode the SVG?
Yes — # and other reserved chars must be escaped (e.g. # becomes %23). This tool handles the encoding for you.
