Generate palettes with harmony rules, lock and edit swatches, extract colors from an image, check WCAG contrast and color-blind safety.

Visually build gradients, layered shadows and border-radius blobs, then copy production-ready CSS.

Convert, resize and compress images right in your browser — nothing is uploaded, and private EXIF data is stripped along the way.

Make a complete favicon set from an emoji, letters or an image — real multi-size .ico, all the PNGs, manifest and HTML tags.

Design a seamless tileable pattern — dots, stripes, hexagons, waves and more — preview it tiled, then export SVG, CSS or PNG.
