- • Perfect for icons, backgrounds, and patterns
About SVG to Data URI Converter
Convert SVG markup to optimized Data URI strings for use in CSS background-image properties or HTML img src attributes. URL-encodes the SVG (which is more efficient than Base64 for SVGs) and optionally minifies it by stripping comments and unnecessary whitespace. Instantly generates the CSS snippet ready to paste into your stylesheet. Perfect for inline SVG icons and background patterns.
All processing happens entirely in your browser using modern web APIs. Nothing is uploaded to our servers — your data stays local and private. Free to use forever, with a Pro plan for power users who want an ad-free experience and API access.
Common use cases
- Embedding SVG icons directly in CSS without HTTP requests
- Using SVG as CSS background-image for pseudo-elements (::before, ::after)
- Generating data URIs for SVG favicons or app icons
- Inlining SVG patterns or decorative graphics in CSS
- Creating self-contained CSS components that include their own icon assets
How it works
SVG Data URIs work by URL-encoding the SVG markup. Unlike images, SVG does not need Base64 encoding — URL encoding is more efficient for SVG because the resulting string is shorter and still valid in CSS. The tool strips the XML declaration, removes comments, collapses whitespace, and then applies encodeURIComponent() to produce a valid data:image/svg+xml,%3Csvg... string.
