SVG to CSS & Data URI Converter

Convert an SVG into a CSS background-image or an optimized data URI — URL-encoded or Base64 — ready to paste into your stylesheet. No hosting and no extra HTTP request.

Free & unlimited URL-encoded or Base64 🔒 Nothing uploaded

Embedding an SVG directly in CSS as a data URI removes a network request and keeps the icon versioned with your styles. URL-encoding is usually smaller than Base64 for SVG, so this converter produces an optimized background-image value you can paste straight into a rule.

How to convert an SVG to a CSS background-image or data URI

  1. Load your SVG. Drop an .svg file or paste the markup into the tool above.
  2. Choose the output. Pick a CSS background-image or a raw data URI, URL-encoded or Base64.
  3. Copy the value. Copy the generated CSS and paste it into your stylesheet.

Frequently asked questions

Should I use URL-encoding or Base64 for an SVG data URI?

URL-encoding is normally smaller and more readable for SVG than Base64. The tool gives you both so you can compare.

Why embed an SVG in CSS at all?

A data URI removes an HTTP request and keeps the graphic versioned alongside your styles — handy for small icons and backgrounds.

Can I optimize the SVG first?

Yes. Run the Optimize tab (SVGO) first to shrink the markup, which makes the resulting data URI smaller too.

Is my SVG uploaded to a server?

No. The conversion runs entirely in your browser.
