What is SVG Base64 encoding?

Base64 encoding converts binary data into a text string that can be embedded directly into HTML, CSS or JavaScript. When applied to an SVG file, the result is a data URI that works as a drop-in replacement for a file URL, without any HTTP request.

When to use SVG Base64

✓Inline icons in CSS without extra HTTP requests
✓Email templates where external URLs are blocked
✓Single-file HTML exports that must be self-contained
✓JavaScript-generated UI where injecting a file URL is not practical
✓Open Graph or meta images that require a data URI

Limitations

Base64 encoding increases the file size by roughly 33 percent compared to the original SVG. For large or frequently used icons, serving the SVG as a separate file is more efficient. Base64 is best suited for small icons and one-off use cases.
