Convert SVG code to CSS background-image data URIs. Supports URL encoding and Base64, with live preview.
About SVG to CSS Converter
The free online SVG to CSS Converter transforms SVG code into CSS-ready data URIs using either URL encoding or Base64 encoding. It supports three output formats — CSS background-image, CSS custom property, and HTML img tag — with a live preview and file size comparison between encoding modes. No signup required, runs entirely in your browser without uploading any files.
How to Use
Paste your SVG code into the editor or click Load Sample to see an example. Select URL Encoded or Base64 encoding mode and choose your output format: CSS background-image for direct property use, CSS Custom Property for design system variables, or HTML img tag for markup embedding. The output updates live as you type. Click Copy output to copy the CSS or data URI to your clipboard for use in your stylesheet.
Common Use Cases
- Front-end developers embedding SVG icons in stylesheets as CSS background images can use this tool to convert icon SVGs to data URIs and eliminate HTTP requests, improving page load performance for icon-heavy interfaces.
- Design system engineers building component libraries can convert icon SVGs to CSS custom properties, enabling theme-level icon swapping via CSS variables without changing markup or importing additional image assets.
- Email template developers who need self-contained HTML with embedded images can use the HTML img tag output to inline SVG logos and icons directly in email markup, avoiding blocked external image loading in email clients.
- Performance-conscious developers can use the size comparison feature to evaluate whether URL encoding or Base64 produces a smaller data URI for a specific SVG, choosing the most bandwidth-efficient encoding for their use case.
- Developers working in environments where SVG files cannot be served as static assets can inline all SVG icons as CSS data URIs to eliminate file dependencies and simplify deployment.
