- Data URI
- A scheme for embedding files directly in URLs.
data:image/svg+xml,...eliminates additional HTTP requests. - URL Encode
- Converts SVG special characters to URL-safe format. Better Gzip compression than Base64.
- Base64
- Binary-to-ASCII encoding. ~33% size increase but universally safe.
- background-image
- CSS property for element backgrounds. Data URIs enable inline SVG backgrounds without external files.
- SVG Optimization
- Removing unnecessary metadata (title, desc, metadata), comments, and whitespace to reduce file size.
This tool uses regex-based lightweight SVG optimization with no external library dependencies.
URL Encode Advantage
URL encoding is recommended over Base64 for SVG Data URIs because URL-encoded SVG text achieves higher Gzip compression ratios.
