SVG to CSS Data URI Converter — Optimized & URL-Encoded

Convert SVG markup into an optimized, URL-encoded data URI ready to paste directly into a CSS background-image: url(...) declaration — with unnecessary whitespace and metadata stripped and characters properly encoded, since a raw unencoded SVG string often breaks when pasted directly into CSS.

How to use SVG to CSS Pro

1. Paste your SVG code.
2. Review the optimized, encoded data URI.
3. Copy it into your background-image CSS.

Frequently asked questions

Why does my raw SVG break when pasted into CSS as a data URI?

Certain characters (like # inside a fill color or unescaped quotes) have special meaning in a URL context and need encoding, which is exactly what this conversion handles automatically.

Does it also minify the SVG?

Yes — unnecessary whitespace and comments are stripped as part of the optimization, keeping the resulting CSS more compact.

When should I inline an SVG as a CSS data URI instead of linking a file?

For small icons where saving an extra HTTP request is worth the inline size — for large or frequently reused SVGs, a separate cacheable file is usually better.
