Base64 Encode SVG for CSS & HTML Embedding

Quick Answer: Encode SVGs as Base64 for embedding in CSS background-image or img src attributes. Note: for CSS, URL-encoding the SVG directly (without Base64) is often smaller and more efficient than Base64.

FAQ

Should I Base64 encode or URL-encode SVGs?

For CSS, URL-encoding the SVG XML directly is usually smaller. Base64 adds 33% overhead. For HTML img src or JSON storage, Base64 works well.

Does Base64 affect SVG quality?

No. Base64 is lossless encoding. The SVG renders identically whether served as a file, inline, or Base64-encoded.
