How to use the CSS to Tailwind Converter

Convert CSS to Tailwind utilities in four steps:

Paste your CSS declarations

Paste CSS property:value pairs into the input. You can paste a full CSS rule block (including selectors and braces) or just the declarations. The tool extracts and processes each property:value pair.

Review per-property mappings

Each CSS declaration shows its matched Tailwind class (or arbitrary value class) alongside notes about the conversion — for example, reminders to replace arbitrary color values with design token classes from your theme.

Copy the combined className

The tool combines all matched Tailwind classes into a single className string ready to paste into your JSX or HTML. Unmatched properties are listed separately for manual handling.

Refine and apply

Review the suggested classes, swap arbitrary values for named theme classes where your design system has them, and apply the className string to your component.

When to use this tool

Use the CSS to Tailwind converter when migrating or translating CSS to a Tailwind-based project:

→Migrating component styles from a traditional CSS or CSS Modules project to a Tailwind-first codebase
→Translating CSS exported from Figma or Adobe XD into Tailwind utility classes for a React component
→Learning which Tailwind utility corresponds to a CSS property you already know well
→Quickly checking if a CSS value maps to a named Tailwind class or requires arbitrary value notation
→Converting inline style objects from legacy React components to Tailwind className strings
→Speeding up Tailwind adoption by converting familiar CSS snippets rather than memorising all utilities
→Auditing a CSS file to estimate how much can be replaced with Tailwind utilities vs custom CSS

Frequently asked questions

Q:How accurate is the CSS to Tailwind conversion?

The conversion is highly accurate for standard CSS values that map directly to named Tailwind utilities — for example, display:flex → flex, padding:16px → p-4, font-weight:700 → font-bold. For values outside the default Tailwind scale (e.g., padding:13px), the tool generates an arbitrary value class like p-[13px]. The output is a strong starting point; replacing arbitrary values with your project's design tokens is recommended for production code.

Q:What happens to CSS values that have no direct Tailwind equivalent?

Properties with values outside the standard Tailwind scale are mapped using Tailwind's arbitrary value notation — for example, width:340px becomes w-[340px] and color:#1a6b4a becomes text-[#1a6b4a]. Some properties (e.g., complex CSS grid templates or animation keyframes) are noted as requiring manual conversion and listed separately in the unmatched section.

Q:Does the converter support Tailwind v3 and v4?

The converter outputs class names using the standard Tailwind utility naming convention, which is compatible with Tailwind v3 and the new Tailwind v4 utility-first approach. Tailwind v4 introduces some new utilities and syntax changes — if you are using v4-specific features, review the converted classes against your version's documentation.

Q:Can I use this to convert styled-components or CSS Modules?

Yes — paste the CSS declarations from a styled-component template literal or a CSS Modules file into the input, and the tool maps each property to its Tailwind equivalent. The selector wrapping is ignored; only the property:value declarations are processed. This makes the tool useful for any CSS-in-JS or file-based CSS migration.

Q:What should I do with the notes on each converted property?

Notes highlight situations where the conversion requires a decision: arbitrary color values should be replaced with your design token class (e.g., text-primary instead of text-[#1a6b4a]), spacing values on non-default scales should be checked against your Tailwind config, and shorthand properties (like border) may need to be split into individual Tailwind utilities for precision.

Q:Is my CSS code sent to any server?

No — all CSS-to-Tailwind mapping runs entirely in your browser. No CSS declarations are sent to a server. This is safe for proprietary design system stylesheets and client project code.
