About Data URIs
What are Data URIs?
Data URIs allow you to embed files directly in HTML, CSS, or JavaScript without external file references. They consist of the data scheme, MIME type, optional encoding, and the encoded data itself.
URL Encoding vs Base64
- • URL Encoding: Produces 30-40% smaller output, recommended for most use cases
- • Base64: More widely compatible but creates larger files (33% increase in size)
Common Use Cases
- • Embedding small icons and logos directly in CSS stylesheets
- • Reducing HTTP requests for better page load performance
- • Creating self-contained HTML emails with inline graphics
- • Building offline-capable web applications
- • Simplifying deployment by eliminating separate image files
Browser Compatibility & Limitations
- • Supported in all modern browsers (Chrome, Firefox, Safari, Edge)
- • Best for small files (under 10KB) to avoid performance issues
- • Cannot be cached separately from the containing document
- • Base64 encoding increases file size by approximately 33%
- • URL encoding preserves most of the original file size
Performance Tips
- • Enable SVG optimization to minimize encoded output size
- • Use URL encoding instead of Base64 when possible
- • Consider external files for large graphics (over 10KB)
- • Data URIs in CSS can be cached with the stylesheet
- • All processing happens in your browser - files never leave your device
About SVG to Data URI
The SVG to Data URI converter transforms SVG vector graphics into embeddable Data URI strings that can be used directly in CSS, HTML, and JavaScript without external file references. This tool supports both URL encoding (recommended for smaller output) and Base64 encoding, with options to optimize SVG content before conversion for maximum efficiency.
Why use a SVG to Data URI?
Converting SVG to Data URI eliminates additional HTTP requests, improves page load performance, and simplifies deployment by embedding graphics directly in stylesheets or markup. Data URIs are perfect for small icons, logos, and decorative graphics, reducing server load and enabling offline functionality. URL-encoded Data URIs are often 30-40% smaller than Base64-encoded alternatives.
Who is it for?
This tool is ideal for web developers optimizing page performance, front-end engineers embedding inline SVG assets, CSS developers creating self-contained stylesheets, React/Vue developers managing component assets, and designers preparing optimized SVG graphics for production websites.
How to use the tool
Upload your SVG files using the file picker or drag-and-drop interface (up to 5 files)
Choose encoding method: URL Encoding (smaller) or Base64 (more compatible)
Select output format: Data URI, CSS Background, HTML Image, or React/JSX
Optional: Enable SVG optimization to remove comments and whitespace before encoding
