How do I convert an SVG to CSS?

Paste your SVG markup or upload an SVG file, then copy the generated CSS. The SVG is embedded as a background-image data URI, so you can apply it to any element with a single class.

Should I use Base64 or URL-encoded SVG in CSS?

Both work in every modern browser. URL-encoded data URIs are usually smaller for SVGs because the markup stays readable, while Base64 is the most universally compatible. You can toggle between them and use whichever is shorter.

Is inlining SVG in CSS better than an image file?

Inlining an SVG as a CSS data URI removes an extra HTTP request and keeps the graphic crisp at any resolution. It is ideal for small icons, loaders and repeating background patterns.

Tips for converting SVG, CSS & Base64

Quick pointers to get the smallest, cleanest output for your project.

SVG to CSS background

Convert an SVG into a ready-to-paste CSS background-image. The SVG is embedded as a data URI, so there are no extra HTTP requests and the graphic stays crisp at any resolution.

Base64 vs URL-encoded

Base64 is the most compatible encoding and works everywhere. URL-encoded data URIs are usually smaller for SVGs because the markup stays human-readable. Toggle between them to see which is shorter for your file.

Decode back to SVG

Paste a CSS rule or a data URI and instantly get the original SVG markup back. Handy for editing an icon that's already inlined in a stylesheet or component.

Optimize before you embed

Enable “Minify / optimize SVG” to strip metadata, comments and redundant attributes. Smaller SVGs mean shorter data URIs and lighter CSS.

Works fully in your browser

Every conversion runs locally — nothing is uploaded. Your SVGs never leave your machine, so it's safe for private icons, logos and brand assets.

Great for icons and patterns

Inline small icons, loaders and repeating background patterns directly in CSS. It's perfect for design systems, email templates and single-file components.

Hi fellow creator!

I'm Jim, the founder, designer & engineer behind the MagicPattern toolbox.

For many years, I was struggling to create engaging visuals for products, branding and interfaces. Their creation required pro design skills or many hours of practice.

That's why I build MagicPattern. My mission is to help people create pro graphics with no effort and no prior design knowledge.
