Câu hỏi thường gặp
How does the converter handle the alpha (transparency) channel?
Alpha is supported in HEX (#RRGGBBAA), RGBA and HSLA — whatever you enter carries over into the other formats that support transparency, while formats without an alpha channel, like plain CMYK, simply ignore it.
Why does the value shift slightly after converting to CMYK and back to HEX?
CMYK is a print-oriented model with no single fixed formula for converting to and from RGB, so a round trip can shift values by a rounding error of a unit or two; visually the color stays effectively the same.
Is my color data sent anywhere?
No, every conversion happens locally in your browser with JavaScript — nothing is uploaded to a server.
