SVG to Data URI: Icons as CSS Backgrounds Without a Sprite Sheet

September 12, 2026

Inline SVGs as CSS background images require URL-encoding the markup by hand, a task that is wrong on the first try and fragile on the second. The encoding is mechanical, so let a tool do it.

Paste SVG markup and get a CSS-ready background-image data URI. Use it for icons and small illustrations that should live in CSS, and keep the source SVG alongside for edits later.

Try it now: open the free tool, runs 100{b8b7921c843ac9e5edcbca134af59decad3ed340e0e3b2e6c286158f277affea} in your browser.

Bottom line: encode the SVG, drop the icon font.

Your turn: use the tool free here, no signup, nothing leaves your device.
