Generate CSS visually and make sense of unformatted JSON, without opening an editor for a two-minute job.

Is the JSON I paste sent to a server?

No. It is parsed entirely in the browser, so API responses and tokens stay on your device.

Is Base64 a form of encryption?

No. It is an encoding that moves binary data through text-only channels, and anyone can reverse it. Never use it to hide secrets.

How do I convert a HEX colour to RGB?

Convert each pair of hex digits in #RRGGBB from base 16 to base 10. #FF8A5B is rgb(255, 138, 91).

Where do I paste the generated CSS?

Drop the background property straight into your stylesheet. Changing the direction or colour stops updates the code live.
