SVG to CSS
Add an SVG file and this page rewrites it as CSS in your browser tab — nothing is uploaded to a server and nothing has to be installed. Only the file representation changes, so check that the CSS result works where the SVG original could not.

SVG 변환에 대한 자주 묻는 질문
Do I need software to turn SVG into CSS?
No. This page runs in the browser tab, so nothing has to be installed to produce the CSS result.
Can I convert more than one file at a time?
Add the files to the list, run the conversion once, and download the results together instead of repeating the upload per file.
Will my original file be changed?
The result is downloaded as a separate file. Keep your original until you have checked the CSS output.
What should I check before using the result?
Open the CSS output in the application that consumes it and spot-check the parts that matter to you; the original file stays untouched if you need to re-run with different options.
Which encoding should I choose?
URL encoding keeps the CSS value more inspectable. Base64 can be convenient when markup characters make copying harder.
Does this optimize or sanitize SVG?
No. It encodes the supplied markup, so inspect and clean untrusted SVG before use.
SVG to CSS Data URI Converter
SVG to CSS conversion creates a CSS background-image value from SVG markup. A data URI can keep a small icon, pattern, or decorative shape inside a stylesheet without a separate image request. This page encodes the SVG text as URL data or Base64 data and places it in a ready-to-copy CSS declaration. It does not optimize paths, sanitize untrusted SVG, remove scripts, host the asset, or decide whether the result suits a particular browser and content security policy.
This page is built for a clear input-to-output task. It gives the browser a file or text value, applies the conversion described above, and leaves the result available for review before download. A successful file download does not mean that every application will interpret the result in the same way. The safest workflow keeps the source file, checks a representative section, and tests the output in the application or player that will receive it.
How to use
Paste SVG markup or choose an SVG text file. Check the source for the dimensions, viewBox, fills, fonts, external references, and any content that should not be embedded. Choose URL-encoded CSS or Base64 CSS, then click Convert. Copy the generated declaration into a test stylesheet and inspect the image at the actual size. Check CSS formatting, data length, and the target site policy before committing the value to a public bundle.
- Choose a supported input file or paste the supported text into the input area.
- Set the options shown for this tool and check that the input is the file type named on the page.
- Click Convert and read the output preview, status message, and any warnings.
- Download the result, then test it in the destination workflow before replacing the source.
Use cases
This tool helps frontend developers make a small icon background, a repeated pattern, a placeholder shape, or a self-contained demo style. It is also useful for documentation examples and quick browser experiments where creating a separate asset is inconvenient. Large illustrations, frequently changed artwork, and assets shared across many pages may be easier to maintain as normal SVG files. Keep the original SVG so future edits do not require decoding a long data URI.
A small browser converter is a good fit for a one-off task, a sample file, a review handoff, or a format check. It is less suitable for an unattended batch pipeline when the file set is large or the output needs a strict schema, printer profile, codec guarantee, or audit trail. For those workflows, keep the mapping and validation rules in the system that owns the data.
Output format
The output is a CSS background-image: url(...) declaration containing the selected encoding. URL encoding keeps the markup visible in encoded form, while Base64 produces a longer opaque value in many cases. The result does not optimize the SVG or guarantee that external fonts, images, scripts, filters, or CSS will behave after embedding. Data URIs can increase stylesheet size and may be restricted by a site content security policy, so test the real page.
The expected result is .css output or the downloadable result described on this page. Source-specific details can change when the input format has no direct equivalent for layout, metadata, styling, timing, searchable text, color, or codec behavior. Review the actual download instead of relying only on the file extension.
Privacy
The SVG is processed in the browser and no image service is required. SVG can contain embedded links, scripts, tracking elements, proprietary artwork, or brand assets. Use files you own or have permission to modify, inspect untrusted input before embedding it, and avoid publishing a copyrighted asset merely because it can be encoded. Treat the generated CSS as a copy of the source artwork.
The page is designed around browser-side processing and does not require an AI API for the conversion described here. The site still loads page assets, and browser extensions, deployment settings, and organizational policy can affect a real environment. Do not use this wording as a legal privacy promise. Use the privacy policy and your own security review for confidential or regulated files.
