Are out-of-range values clamped?

No. Values outside 0–255 return an error so you know the input is invalid.

Is the hash included?

Yes. Output uses #RRGGBB uppercase by default.

No. Conversion is client-side only.

Yes. Comma-separated integers such as 51, 102, 153 are accepted alongside full rgb(51, 102, 153) syntax.

Out-of-range channels or missing values produce an error instead of clamping. Fix inputs to integers between 0 and 255.

Enter RGB channel values or paste an rgb() string to get an uppercase hex code. Invalid channels show a clear, field-level error.

Channels must be integers from 0 to 255.
