What is SVG to CSS?#
SVG to CSS turns SVG markup into CSS you can paste into a stylesheet. Apply the SVG as a mask or a background, then copy the result as CSS declarations, Tailwind classes, or a data URL.
Paste the markup or load an .svg file, and the output updates as you work. Everything runs in your browser, so your markup never leaves your device.
How to Use#
- Paste SVG markup, or load an .svg file.
- Choose how to apply the SVG (mask or background) and how to encode the data URL (URL-encoded or base64).
- Pick the output format (CSS, Tailwind, or data URL), then copy the result.
The preview shows the SVG at three sizes on a checkerboard. When a mask is selected, the color control changes the preview only.
Mask or Background#
- Mask: paints the SVG as a single-color silhouette using
currentColor, so it follows the element's text color. Suits icons that need color variations. - Background: draws the SVG with its own colors through
background-image. Its colors cannot be changed from CSS.
Output Formats#
- CSS: ready-to-paste declarations, including repeat, size, and position.
- Tailwind: the same result as utility classes, using arbitrary values for the data URL.
- Data URL: the encoded
data:image/svg+xml,...string on its own, for use in your own code.
The data URL is URL-encoded by default. Switch to base64 to pack the content uniformly.
Common Use Cases#
- Turning a logo or pictogram into a CSS mask that matches link or button colors.
- Inlining a small SVG background without adding an image file to the project.
- Preparing Tailwind-ready classes for a component library.
- Converting an exported .svg file into a paste-ready snippet for a stylesheet.
FAQ#
Yes. Choose, drop, or paste a single .svg file and its contents load into the tool for the same conversion. Files in other formats are ignored, so the current input stays as it is.
The tool never rewrites fills or strokes. To recolor, choose a mask instead of a background.
Pick a mask when the SVG should take on the color of its surroundings, such as a link or a button in different states. Pick a background when the artwork must keep its own colors.
It becomes a single-color silhouette based on transparency, so the original fill colors are lost. Use a background when the colors must stay.
Only lightly: comments and metadata are removed, a missing SVG namespace is added, and width and height are dropped when a viewBox is present so it can scale. Fills, strokes, ids, and defs are left as they are.
No. The CSS and Tailwind outputs include repeat, size, and position, so they render as they are. Give the element a size, and for a mask, a text color.
Yes. It uses arbitrary value notation such as bg-[url(...)] and [mask-image:...], which Tailwind v4 supports.
Notes#
- A data URL grows the markup: base64 adds about a third, and URL-encoding expands special characters. Large SVGs produce long outputs.
