Seamless Bridge Between Web & Print

Web developers work primarily with RGB and HEX strings, whereas UI design systems often leverage HSL for creating accessible color steps. Meanwhile, graphic designers preparing assets for physical print workflows must translate screens into four-color process CMYK. FileConvert simplifies this workflow by keeping all four models synchronized in real time.

100% Private In-Browser Tool

Everything runs directly on your device using client-side JavaScript. No color requests or analytics are transmitted to third-party endpoints.

Frequently Asked Questions

What is the difference between RGB and CMYK?

RGB (Red, Green, Blue) is an additive color model used for illuminated digital screens. CMYK (Cyan, Magenta, Yellow, Key/Black) is a subtractive color model designed for commercial ink printing.

Why is HSL favored by web designers?

HSL (Hue, Saturation, Lightness) aligns with human color perception. It makes creating tints, shades, and complementary color schemes much more intuitive than adjusting raw hex or RGB channels.

Are my custom palette selections tracked or logged?

No. All color math, color space transformations, and conversions occur entirely in your local browser sandbox without server interaction.

Does this tool support 3-digit and 6-digit hex codes?

Yes. Short shorthand hex codes like #fff or #4f6 are automatically expanded into their full 6-digit representations.
