Visual generators

Draw a QR from text you type, or expand one hex color into a small harmony. Both jobs run in this tab. Neither one uploads your input.

QR codes

The QR code generator encodes UTF-8 bytes as Model 2 byte-mode symbols, versions 1 to 40, with error correction L, M, Q, or H. Preview is SVG. There is no logo in the center and no network encoder.

Palettes from one hex

The color palette walks complementary, analogous, triadic, split, tetradic, or mono relationships in HSL, then prints sRGB hex. That is a seed, not a design system. Convert a single color or check contrast on the color converter and color contrast pages. This group does not include a CSS gradient builder.

Color Palette Generator Start from one hex color. The page walks HSL hue (or lightness for mono) and prints matching sRGB hex values. This is not a full design system.
QR Code Generator Type a URL or other text. The page encodes it locally as an SVG QR. Error correction is L, M, Q, or H. There is no logo overlay.
