SVG Data URI Converter

When to use?

Use it to put a small icon SVG directly into a CSS background or HTML img without a separate file request, or to embed SVG inline to reduce HTTP requests.

How to use

• Paste SVG code into the input.
• Choose the encoding (URL encoding or Base64).
• Check the preview and copy the Data URI, CSS, or HTML snippet.

Input Explanation

Paste SVG code with an <svg> tag. URL encoding is smaller and recommended for CSS; Base64 has broader compatibility.

Calculation Basis

It tidies unnecessary whitespace in the SVG, then encodes. URL encoding leaves some characters as-is to reduce size; Base64 converts the whole into a base-64 string.

Usage Examples

• Embed CSS icons - Put a small icon SVG directly in CSS background-image to reduce requests.
• HTML inline image - Put SVG in <img> src as a Data URI to display without an external file.
• Single-file delivery - Embed SVG in code to deliver without a separate file.

Examples

• Icon SVG → data:image/svg+xml,... (for CSS background-image)
• Auto-generates background-image and <img> snippets

Cautions

• Malformed source data can cause parsing errors or broken output.
• A mismatched encoding standard or complex nested data may break or drop the structure.

Guides

URL encoding vs. Base64

URL encoding leaves some characters as-is and is smaller, suiting CSS backgrounds. Base64 is broadly compatible but the result string is longer.

Where to use Data URIs

Embedding small icons as Data URIs reduces HTTP requests. For large SVGs, an external file is better for caching.

FAQ

URL encoding or Base64 — which is better?

URL encoding (smaller) for CSS backgrounds; Base64 when compatibility matters.

Can I see the result?

The preview in the result area shows whether the converted SVG renders correctly.

Are large SVGs converted?

Conversion works, but if the Data URI gets very long, keeping it as an external file is more efficient.

Does it generate CSS and HTML code?

Yes. It provides both a background-image snippet and an <img> tag snippet.
