Question 1

What is SVG to CSS conversion?

Accepted Answer

SVG to CSS conversion encodes your SVG image as a base64 data URI and embeds it directly in your CSS as a background-image. This eliminates the need for separate image files, reducing HTTP requests and making your icons and graphics instantly load with your stylesheet.

Question 2

Why use SVG as CSS background instead of img tag?

Accepted Answer

Using SVG as CSS background offers several advantages: reduces HTTP requests by embedding the image in CSS, works with pseudo-elements like ::before and ::after, can be easily reused across multiple elements, enables CSS-only hover effects, and better caching when bundled with CSS.

Question 3

Will the CSS work in all browsers?

Accepted Answer

Yes! Data URI SVG backgrounds work in all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. For IE11, you may need to URL-encode the SVG instead of base64 encoding.

Question 4

How do I change the SVG color in CSS?

Accepted Answer

To change SVG colors via CSS, the SVG must use 'currentColor' for fill/stroke values. Then you can control the color using the CSS 'color' property on the element. Alternatively, you can modify the SVG code directly before conversion, or use CSS filters.

Question 5

What's the difference between base64 and URL-encoded?

Accepted Answer

Base64 encoding converts SVG to a compact text format but increases file size by ~33%. URL encoding keeps the SVG readable and often results in smaller output for simple SVGs. Base64 has better browser compatibility, while URL encoding is more efficient for small icons.

Question 6

Is there a file size limit?

Accepted Answer

There's no strict limit, but for best performance, keep SVGs under 10KB. Larger SVGs may increase your CSS file size significantly. For large graphics, consider using external SVG files instead of data URIs.

Question 7

Can I use the generated CSS in any framework?

Accepted Answer

Yes! The generated CSS works in any framework or vanilla CSS. It's compatible with React, Vue, Angular, Svelte, plain HTML/CSS, and CSS-in-JS solutions.

Question 8

How do I make the SVG responsive?

Accepted Answer

Use background-size: contain or cover to make the SVG scale responsively. For full control, remove fixed width/height from the SVG and use viewBox attribute instead.

Question 9

Is my SVG data secure?

Accepted Answer

Absolutely! All SVG processing happens entirely in your browser. Your SVG files are never uploaded to any server. The conversion runs locally using JavaScript.
