Why Use This Converter?
Everything you need to turn SVGs into production-ready CSS — nothing you don't.
Automatically strips editor metadata, comments, and redundant attributes. Typical savings of 30–70%.
Your SVG never leaves the browser. All processing happens locally with JavaScript — zero uploads.
See your SVG rendered as a CSS background on a checkerboard canvas in real time as you edit.
Generate code for background-image, border-image, or mask — with correct property syntax for each.
Copy the ready-to-paste CSS declaration directly to your clipboard with a single click.
No account, no rate limits, no watermarks. Just paste your SVG and get your CSS instantly.
How to Convert SVG to CSS
From paste to production in four steps.
- Step 1Paste or upload your SVG
Paste SVG code into the editor, drag & drop an .svg file, or click Upload to browse. You can also load the built-in example to try the tool instantly.
- Step 2Choose a CSS property
Select background-image, border-image, or mask depending on how you want to use the SVG. The output CSS adapts automatically with the correct syntax.
- Step 3Optimize with SVGO (optional)
Toggle SVGO to strip editor bloat from SVGs exported from Figma, Illustrator, or Inkscape. Smaller SVG = shorter CSS = faster pages.
- Step 4Copy the CSS and use it
Hit Copy CSS to send the full declaration to your clipboard, then paste it directly into your stylesheet. The live preview confirms it works.
Tips & Related Tools
Get the most out of SVG in CSS with these practical tips.
Without a viewBox attribute, SVG backgrounds won't scale correctly when the element resizes. Most SVG editors add it automatically, but double-check when writing SVGs by hand.
Replace hardcoded fill or stroke colors with currentColor. This lets you control the SVG color purely with the CSS color property, making dark-mode support trivial.
SVGs with <text> elements that reference external fonts won't render those fonts when used as a CSS background. Convert text to paths in your SVG editor before exporting.
For the smallest possible output, run your SVG through SVGLite to strip unnecessary markup, then paste the result here for encoding.

Frequently Asked Questions
Everything you need to know about SVG data URIs in CSS.
A data URI embeds file content directly inside a URL string. For SVGs, this means writing the raw XML into a url("data:image/svg+xml,...") value in your CSS — no separate file, no HTTP request. Unlike base64 encoding, this approach keeps the SVG source readable and results in a smaller payload.
CSS backgrounds unlock patterns that HTML cannot — you can apply SVGs to ::before and ::after pseudo-elements, use them as masks to clip content, or tile them across an element. They're ideal for decorative patterns, icons used in CSS-generated content, and UI components where adding DOM nodes is impractical.
SVGO (SVG Optimizer) is an open-source tool that removes editor-specific metadata, redundant attributes, comments, and hidden elements that visual tools like Figma and Illustrator include on export. A raw Figma export can be 50–70% larger than necessary. Smaller SVG = shorter CSS data URI = less for the browser to parse.
Yes. All processing runs entirely in your browser using JavaScript. Your SVG is never uploaded to any server. You can use this tool on sensitive or proprietary artwork without any privacy concerns.
background-image renders the SVG as a decorative background fill behind an element's content. mask uses the SVG's luminance or alpha channel to clip what is visible — great for cutout effects. border-image slices the SVG across an element's border area, useful for custom frame decorations. Each mode outputs the correct CSS syntax for that property.
Base64 encoding inflates any binary or text payload by approximately 33%. The smart encoding used here replaces only the characters that must be encoded for CSS (<, >, ", #, %) — resulting in a significantly shorter output that stays human-readable in DevTools and works in all modern browsers.
All modern browsers: Chrome 4+, Firefox 3.5+, Safari 3.2+, Edge (all versions), Opera 10.6+. Internet Explorer 9+ also supports them, though IE 8 does not. For the mask property, this tool automatically outputs both the -webkit-mask prefix and the standard mask declaration.
There is no hard limit in the CSS specification, but practical limits exist. Very large SVGs (over 100 KB) encoded as data URIs can slow down CSS parsing and repaint performance, especially on mobile. For large or complex SVGs, consider using an external .svg file reference or inline SVG in the HTML instead. Enable SVGO to reduce size before encoding.
