ℹ️ About CSS to Tailwind
Paste a CSS rule set and this converter returns the equivalent Tailwind utility classes, grouped under each selector. It maps declarations against Tailwind's default scales — spacing, text-xs through text-9xl, rounded-lg, gray-700 and the rest — and falls back to arbitrary values such as p-[13px] when nothing matches, while listing any declarations it could not convert. Useful when migrating a legacy stylesheet or an old component to Tailwind. Parsing happens in your browser; the CSS is never uploaded.
💡 Use Cases
📋 How to use
Paste a CSS rule or a whole block of declarations into the CSS box on the left, or click Sample to load an example.
Watch the Tailwind CSS panel on the right fill in as you type, mapping each property and value to its utility class.
Check the output selector by selector: each rule appears as a comment header followed by the class list you can paste into a class attribute.
Open the yellow Unsupported properties box to see any declarations with no Tailwind equivalent, listed with their selector, so you can handle them by hand.
Click Copy to take the generated classes to your clipboard.
Click Clear to empty both panels before pasting your next block of CSS.
💎 Pro Tips
- Paste your content directly — the CSS To Tailwind detects common input patterns and applies sensible defaults automatically.
- Use keyboard shortcuts (Ctrl/Cmd+A to select all, Ctrl/Cmd+C to copy) to speed up your workflow inside the CSS To Tailwind.
- For very large inputs, break them into chunks — most browser tabs can handle megabytes of text, but parsing huge payloads may freeze the UI briefly.

- Combine the CSS To Tailwind with other tools on this site (formatters, converters, encoders) to build complete data pipelines without leaving your browser.
