SVG to Data URI / Base64 Converter

SVG markup
Data URI

Why this tool exists

A focused workflow, without the design-app overhead

A data URI packages the SVG markup into a value that CSS or HTML can use without a separate asset request. Generate both compact URL-encoded output and base64 when a target system requires it.

Useful for

  • Small CSS background images and masks
  • Self-contained HTML prototypes and documentation
  • Systems that only accept a single image URL value

How to use it

From input to finished asset

  1. 01

    Supply the SVG

    Paste markup or load a file. The preview helps catch malformed input before encoding.

  2. 02

    Pick an encoding

    Use URL encoding for readable CSS, or base64 for tools that explicitly require it.

  3. 03

    Copy the right snippet

    Copy the raw URI, a CSS background declaration, or a ready-to-use img element.

URL encoding is often smaller

For text-heavy SVG markup, a carefully escaped data URI is commonly shorter than base64 and remains partly readable.

Best for small assets

Inlining large artwork increases HTML or CSS size and prevents separate browser caching. Keep external files for substantial illustrations.

CSS-ready escaping

The generated CSS snippet is quoted and escapes SVG characters that would otherwise break a declaration.

No upload required

Encoding and snippet generation are handled entirely in your browser.

Common questions

Why would I convert SVG to a data URI?+

Data URIs let you embed the SVG directly in CSS (background-image) or an <img> tag — one fewer HTTP request and no separate asset file.

Do I need to upload my file to use SVG to Data URI / Base64 Converter?+

No. This tool runs in your browser, so your SVG stays in the current tab and is not uploaded to GenSVG.

Can I use the exported SVG in a commercial project?+

The tool does not add a watermark or a new license. Your right to use the result depends on the license and ownership of the source artwork you provide.
