Convert SVG to Base64 Data URI for embedding in CSS and HTML.
SVG to Base64 is a free online tool that converts SVG code into Base64-encoded Data URIs for embedding directly in CSS and HTML. Eliminate extra HTTP requests by inlining SVG graphics as data URIs in your stylesheets and markup. Embedding SVGs as Base64 Data URIs is a common performance optimization technique. Instead of making a separate HTTP request to load an SVG file, the encoded data is embedded directly in your CSS (as a background-image) or HTML (as an img src). This reduces the number of network requests, which is especially beneficial for small, frequently-used graphics like icons and logos. The tool generates both CSS background-image syntax and HTML img tag syntax, so you can use the embedding method that fits your use case. It also shows the encoded size so you can evaluate whether inlining is worth it (generally recommended for SVGs under 10KB). Everything runs entirely in your browser. Your SVG code is never sent to any server. There are no usage limits and no account required. Common use cases include embedding icons in CSS for single-file stylesheets, inlining small SVG logos in HTML templates, creating self-contained HTML emails with embedded graphics, reducing HTTP requests for performance optimization, and embedding SVGs in JavaScript-generated markup.
