SVG to CSS/Base64
Convert SVG code to CSS Data URI or Base64 for inline backgrounds.
📖 About SVG to CSS Conversion
Converting SVG to CSS Data URI or Base64 allows you to embed images directly in your CSS, reducing HTTP requests and improving page load performance.
Format Comparison
- Data URI (Recommended) - Smallest size, uses URL encoding. Best for most use cases.
- Base64 - Larger size (~33% bigger), but more compatible with older systems.
- URL Encoded - Similar to Data URI, keeps special characters encoded.
When to Use Inline SVG
- Small icons and decorative elements
- CSS backgrounds and patterns
- Reducing HTTP requests for better performance
- Ensuring assets load with the CSS file
💡 Pro Tip: For SVGs larger than 10KB, it's usually better to use external files. Inline SVGs increase CSS file size and can't be cached separately.
❓ Frequently Asked Questions
For most cases, use Data URI. It produces the smallest output and works in all modern browsers. Use Base64 only if you need compatibility with very old systems or specific encoding requirements.
Base64 encoding represents binary data using 64 ASCII characters. This encoding process increases the size by approximately 33%. Data URI with URL encoding is more efficient for text-based formats like SVG.
Yes, but complex SVGs with many elements may result in very long CSS strings. Consider optimizing your SVG first using our SVG Optimizer tool before converting to CSS.
Data URIs are supported in all modern browsers including Chrome, Firefox, Safari, Edge, and IE9+. For maximum compatibility, use Base64 encoding.
