SVG to CSS converts a pasted SVG into a CSS background-image or mask rule, producing a compact URL-encoded data URI with a ready selector snippet. Masks can be recolored with a single background-color. It offers a live preview and one-click copy, runs free in-browser, and uploads nothing.
The GigAI SVG to CSS converter turns raw SVG markup into a production-ready CSS rule you can paste straight into a stylesheet. No image file, no extra HTTP request, no build step. It encodes your SVG as a smart URL-optimized data URI (single-quoted attributes plus minimal percent-encoding of only the characters that break inside a CSS url()), which is dramatically smaller and more readable than the usual base64 blob, then wraps it in a ready selector so the artwork drops in as either a background-image or a mask. Background mode gives you a self-contained, crisply scalable image sized with no-repeat center / contain. Mask mode is the developer favorite: the SVG becomes an alpha mask (with the -webkit- prefix for Safari) and the shape takes its color from a single background-color: currentColor line, so one icon inherits your text color and adapts to light and dark themes without a second file. You choose the CSS selector, switch modes live, and see the exact rule render next to a real preview of the artwork. Because encoding runs entirely in your browser with no upload, your logos, unreleased icons and client assets never leave your machine. It's the fast, private path from an SVG export to an inline-in-CSS icon that ships without a single network round-trip.

Paste SVG markup into the editor, drop a .svg file anywhere on the workspace, or load a built-in example to see the CSS instantly.
Choose background-image for a self-contained image, or mask to make the shape recolorable with background-color / currentColor.
Type the CSS selector the rule should target (a class, an element, or a pseudo-element like.btn::before) and the snippet updates live.
Confirm the artwork in the preview, then copy the rule to your clipboard or download it as a .css file and paste it into your stylesheet.
Emit the SVG as a self-contained background-image, or as a CSS mask that inherits its color from background-color: currentColor. Flip modes and the whole rule regenerates live.
Instead of a bulky base64 blob, the SVG is single-quoted and only the characters that break inside url() are percent-encoded: a smaller, human-readable payload that gzips well and stays inline.
In mask mode the shape becomes an alpha mask, so background-color (or currentColor) sets its color. One icon covers every theme. No duplicate files for light and dark.
Name the CSS selector the rule attaches to (.icon,.btn::before, [data-icon='menu']) and the snippet is ready to paste with zero find-and-replace afterwards.
A checkerboard preview renders the actual SVG next to the generated rule, with light/dark backgrounds and zoom, so you confirm the artwork before you copy it into your stylesheet.
The data URI lives inside the CSS, so the icon paints with the stylesheet. No separate image file, no waterfall, no flash of missing icon on first render.
Small UI marks (arrows, chevrons, spinners, brand glyphs) belong in the CSS, not in a network waterfall. Inlining them removes a request and the flash of a late-loading image.
Mask mode plus currentColor means a single rule recolors itself for hover, dark mode, or a disabled state. Set the text color and the icon follows, no second asset required.
URL-optimized encoding keeps SVG readable and typically smaller than base64, so your stylesheet stays lean and the payload compresses well over the wire.
Encoding happens locally in your browser. Unreleased logos, client artwork and internal icons never leave your machine. Nothing is uploaded, stored or logged.
From quick one-off fixes to daily workflows, see how people put this tool to use.
Turn a chevron or spinner into a background-image rule so it paints with the stylesheet, one fewer request and no late-loading flash on first render.
Emit a mask rule with currentColor so a single .icon class recolors for hover, dark mode and disabled states without a second file per theme.
Drop a self-contained data-URI background into a component's CSS so the artwork travels with the markup instead of relying on an external image host.
Paste the generated background-image value into a page-builder's custom-CSS box to set a decorative shape or pattern with no upload step.
Accepts SVG, and produces CSS, all processed locally in your browser.
Convert SVG to a clean React component in your browser, camelCased attributes, TypeScript or JS, memo, forwardRef and React Native output, with a live preview. Nothing is uploaded.
Minify and clean SVG files in your browser with SVGO, strip editor metadata, round coordinates, drop hidden layers and see the exact bytes and percentage saved. Nothing is uploaded.
Aggressively minify SVG online: collapse whitespace, strip comments, metadata and editor namespaces, and squeeze markup to a single line with a live before/after size and % saved. 100% in your browser.
Open, paste or drop an SVG to view it on a checkerboard, light or dark canvas with zoom, live dimensions, a source-code pane and a full element/color report: 100% in your browser, nothing uploaded.
Shrink JPG, PNG and WebP images without a visible quality drop. Set the quality yourself, or compress to an exact target size like 100 KB. Free, entirely in your browser.
Decode a data:image/svg+xml URI back into raw SVG in your browser, handles base64 and URL-encoded payloads, with a live preview and one-click.svg download. Nothing is uploaded.
Hit a snag? Here are quick fixes for the issues people run into most.
background-image renders the SVG's own colors verbatim. CSS color has no effect on it. To recolor, switch to mask mode and set background-color (or currentColor), or edit fill in the SVG source before converting.
The rule already includes both mask and -webkit-mask. If it still fails, make sure the SVG has an explicit viewBox and non-zero size, and that no parent sets overflow or transform that clips the masked box.
Add a viewBox to the SVG so it scales cleanly, and size the element to the icon's aspect ratio. The rule uses center / contain, so a mismatched box leaves empty space or crops: set width/height on the element to match.
Some pipelines re-encode data URIs. If a tool mangles the single-quoted attributes, wrap the whole value in double quotes (already done here) or switch the SVG's inner quotes, then re-copy the rule.
Use mask mode for monochrome icons you want to recolor: background-color (or currentColor) sets the shape's color, so one rule serves every theme.
Run your SVG through the SVG Optimizer first, fewer nodes and no editor metadata means a shorter data URI and a lighter stylesheet.
Set fill="currentColor" in the source for background mode. For mask mode the fill is ignored and color comes from background-color instead.
Target a pseudo-element like.btn::before as the selector when the icon is decorative. It keeps your HTML clean and the icon out of the accessibility tree.
Keep the SVG small (a UI glyph, not a detailed illustration). Huge artwork makes an unwieldy data URI that bloats the CSS file.
Recent updates and improvements to the svg to css.
Initial release, live SVG→CSS conversion with background-image and mask modes, a compact URL-optimized data URI, a custom selector, live preview, and copy/download.
Added undo/redo history, keyboard shortcuts, curated examples, and a shareable-link option that reopens the tool with your SVG pre-loaded.
Added a payload size readout comparing the URL-optimized data URI against base64, and clearer guidance for recoloring in mask mode.
Every conversion runs entirely in your browser. Your SVG is encoded on your device and never uploaded to any server. Nothing is stored, logged or transmitted, so you can safely convert unreleased logos, client artwork or internal icons. Close the tab and every trace is gone.
Free, private and instant. SVG to CSS runs right in your browser.
