COLOR VALUE CONVERTER
Turn RGBA into copy-ready HEX
Use a CSS color or numeric channels. The converter validates every boundary, rounds channels explicitly, and keeps the alpha rule visible.
Examples: rgba(39, 54, 42, 0.24), rgb(39 54 42), or 39, 54, 42, 24%.

使用步骤
如何使用
- Paste a CSS rgba(), rgb(), or comma-separated numeric value, or enter channels directly.
- Choose six digit HEX for opaque color or eight digit HEX when you need alpha.
- Copy the HEX, RGB, or CSS result and use it in your stylesheet or design token.
Accepted color input
Use rgb(r, g, b), rgba(r, g, b, a), or four numeric fields. RGB channels accept integers or decimals from 0 to 255 and are rounded to the nearest integer. Alpha is optional and defaults to 1; use a decimal from 0 to 1 or a percentage from 0% to 100%.
HEX and alpha rules
Six digit HEX always contains only red, green, and blue. Eight digit HEX appends alpha as two hexadecimal digits in CSS #RRGGBBAA order. Alpha is converted with round(alpha × 255), so 0.24 becomes 61 and 3D.
Local and bounded
Parsing and conversion run in this browser. Input is limited to 200 characters, RGB channels must stay within 0–255, and alpha must stay within 0–1 or 0–100%. No color profile or named-color lookup is applied.
常见问题
你可能还想知道
What does an omitted alpha value mean?
It means fully opaque: alpha is 1, or 255 in an eight digit HEX value.
How is decimal RGB rounded?
Each channel is rounded to the nearest integer, then clamped only after validating that it is within 0–255.
Which HEX alpha order does this tool use?
The output follows CSS #RRGGBBAA order, with alpha in the final two hexadecimal digits.
Does the converter upload my color?
No. Conversion, copying, and validation happen locally in your browser.
