100% Client-Side Processing

When you use Color Converter, your data never leaves your browser. All transformations execute in-memory on your local machine with zero server uploads. Web assets are downloaded to run the tool, but your input data is never transmitted.

Frequently Asked Questions

Is anything uploaded?

No. Conversion runs in your browser. The page does download the code needed to run the tool.

Which inputs are accepted?

HEX with 3 or 6 digits (the # is optional), rgb() with 0 to 255 per channel, and hsl() with a hue in degrees and saturation and lightness from 0 to 100. Commas or spaces both work.

Why does HSL round-trip not always return my exact input?

RGB is whole numbers and HSL is shown rounded to whole degrees and percents, so some HSL values map to the same RGB color. HEX and RGB are always exact.

Is transparency (alpha) supported?

Not yet. #RRGGBBAA, rgba(), and hsla() are rejected with a clear message rather than silently dropping the alpha.
