Convert SVG markup into an optimized data URI for embedding.
About SVG to Data URI
SVG to Data URI converts SVG markup into an optimized data URI string that can be embedded directly in HTML img src attributes, CSS background-image properties, or JavaScript variables without requiring a separate HTTP request for the SVG file. A data URI encodes the resource inline in the document using either URL encoding or Base64, eliminating a network round-trip and simplifying deployment of SVG icons, logos, and decorative graphics in web applications. URL-encoded data URIs are generally preferred over Base64 for SVGs because they are more compact and remain partially human-readable in browser developer tools. The tool optionally minifies the SVG markup before encoding to reduce the final data URI size.
How to Use
Paste your SVG code into the input area and the data URI is generated instantly in the output panel. Choose between URL encoding and Base64 encoding using the format toggle: URL encoding produces smaller output for most SVGs while Base64 is safer for SVG content containing unusual characters that could break HTML attribute parsing. Copy the full data URI string and paste it into a CSS background-image url() value, an HTML img src attribute, or a JavaScript constant. A live preview of the rendered SVG is shown so you can verify visual correctness before copying the output.
Common Use Cases
- Embedding SVG icons as CSS background-image data URIs in component stylesheets to eliminate extra HTTP requests for small vector assets
- Inlining company logos and marketing illustrations as data URIs in HTML email templates where external image loading is blocked by email clients
- Converting SVG favicons, app icons, and cursors to data URIs for inline embedding in single-file HTML documents and browser extensions
- Inlining critical above-the-fold SVG content as data URIs to eliminate render-blocking network requests for initial page load
- Assigning SVG mask images, patterns, and filters as data URIs in CSS for self-contained, portable component stylesheets
