SVG to Base64 Converter — Encode SVG for CSS & HTML
Convert SVG markup to base64 data URLs for inline CSS background images and HTML embedding. Choose between base64 or URL-encoded output and copy the ready-to-use CSS url() or HTML img src.
How to Use SVG to Base64 Converter — Encode SVG for CSS & HTML
How to Use the SVG to Base64 Data URL Encoder
Step 1: Paste Your SVG
Paste your SVG markup into the input field. Make sure it includes the <svg> element with the xmlns attribute (xmlns="http://www.w3.org/2000/svg") for maximum browser compatibility.
Step 2: Choose an Encoding Method
- Base64 — encodes the SVG as a base64 string (
data:image/svg+xml;base64,...). Universally supported and increases file size by ~33%. - URL-Encoded — encodes only the characters that are unsafe in URLs (
#,%, quotes). Usually produces a shorter result than base64 for SVGs and keeps the markup readable.
Step 3: Encode
Click Encode to Data URL (or press Ctrl+Enter). A live preview of the SVG appears alongside a size comparison showing the original and encoded sizes.
Step 4: Copy an Output Format
Click Copy next to the format you need:
- Data URL — the raw
data:image/svg+xml;...string - CSS url() — wrapped in
url("...")for direct use in CSS - background-image — a complete
background-image: url("...");declaration - HTML
<img>— a ready-to-paste<img src="..." />tag
