Frequently Asked Questions

Why embed SVGs?

Zero extra requests for icons and logos — inline data URIs load with the CSS. Small assets only; large illustrations bloat stylesheets.

Size overhead?

+33% Base64 expansion plus URL-encoding — a 3 KB icon becomes ~4.5 KB of CSS. Worth it under ~10 KB total.

UTF-8 vs Base64?

UTF-8-encoded SVG (smaller, readable) vs Base64 (bulletproof with special chars). Modern browsers accept both in url().

Is artwork uploaded?

No — encoding runs locally in your browser. Artwork never leaves your device.
