What is an SVG to Base64 Converter?
An SVG to Base64 converter is a tool that transforms Scalable Vector Graphics (SVG) into a Base64-encoded string. This string can be used as a Data URI in HTML (img src) or CSS (background-image), allowing you to embed the image directly into your code. This eliminates the need for a separate HTTP request to fetch the image file, which can improve page load performance for small icons and graphics. Our tool handles this conversion entirely in your browser for privacy and speed.
