Frequently Asked Questions
Why is UTF-8 Data URI better than Base64 for SVG?
UTF-8 URI encoding is ~30% smaller than Base64, remains human-readable in CSS stylesheets, and compresses better with Gzip/Brotli.
Does the converter sanitize quotes and newlines?
Yes, spaces, newlines, and special characters are safely percent-encoded to prevent CSS syntax breakage.
