# Data URI Generator

> Turn text, SVG or CSS into a data: URI you can inline directly in HTML or stylesheets.

To create a data URI, paste your content and pick its MIME type. The result can be inlined directly in an img src, a CSS background or a fetch call, removing one network request. URL-encoding is usually smaller than Base64 for SVG.

## FAQ

### Should I use Base64 or URL-encoding for SVG?

URL-encoding is usually 20–30% smaller for SVG because the markup is mostly ASCII already. Base64 inflates any content by roughly a third regardless of what it contains.
