SVG to Base64
Paste SVG, a data URI, an image URL, or drop a file. The tool auto-encodes, decodes SVG data URIs back to markup, and prepares CSS-ready output.
Input
Paste SVG or encoded data URI. You can also drop a file or fetch a remote image URL.
Primary Output
Encoded result will appear here automatically
Paste something on the left and the transformation will start automatically
How SVG to Base64 Works
Encode SVG files into Base64 data URIs or decode them back to markup. Get CSS-ready output for inline embedding.
SVG to Data URI
Encode any SVG file or markup into a Base64 data URI ready for inline use in CSS, HTML, or JavaScript. Eliminate an extra HTTP request per icon.
Decode Back to SVG
Paste a Base64-encoded data URI and the tool instantly extracts the original SVG markup. Inspect or edit embedded SVGs without external tools.
CSS-Ready Output
Get a background-image CSS snippet you can paste directly into your stylesheet. The output is URL-encoded and optimized for minimal size.
Multiple Input Methods
Paste SVG code, drop an .svg file, or enter a URL pointing to an SVG. The tool auto-detects the input type and converts it immediately.
Frequently Asked Questions
Embedding SVGs as Base64 data URIs eliminates an HTTP request, which can improve load time for small icons and UI elements. It is especially useful in CSS where you cannot inline SVG markup directly.
Yes, Base64 adds roughly 33% overhead. For very small SVGs (under 1-2 KB) this is usually worth the saved HTTP request. For larger SVGs, serving them as separate files with proper caching is more efficient.
Both can be used as data URIs. URL-encoded SVG keeps the markup human-readable and is typically smaller than Base64. Base64 is more universally supported in older email clients and some edge cases. This tool provides both options.
Yes. Simple icons, complex illustrations, animated SVGs — any valid SVG markup can be encoded. However, SVGs with external references (linked images or fonts) may not render correctly when embedded as a data URI.
