One workspace for mixed palette files

Open JSON, ASE, ACO, CSS, SVG, TXT or SSS files and combine their colors into one editable palette. Every swatch shows its name and hexadecimal value, ready to rename, copy or remove.

Clean, arrange and export

  • Exclude black, white, exact grays and duplicate values.
  • Replace transparency with full opacity when required.
  • Sort by hue, saturation, brightness, luminance or UI-oriented grouping.
  • Export the result as JSON, ASE, ACO, SVG or CSS custom properties.

From import to finished palette

  1. Select one or several supported files.
  2. Choose filters and a sorting method.
  3. Review names and swatches, then enter a palette name.
  4. Download the format needed by your design or development workflow.

Files are processed locally and are not uploaded. Settings remain in browser storage; imported palettes stay only for the current session. CSS and SVG imports read supported declarations but do not evaluate stylesheets, gradients or computed colors.

For design and code palettes

Designers, frontend developers and illustrators can inspect, clean or convert existing color collections without installing a desktop utility. New colors cannot be created from scratch; every workspace begins with imported files.

Non-RGB Adobe colors are converted to RGB for editing and export, so the original color model and spot-color metadata are not retained. There is no account, cloud storage, synchronization or collaborative editing.

Primary controls work from the keyboard, but clickable swatches are not keyboard-focusable controls and the palette is not exposed as a structured table for screen readers. Animations ignore reduced-motion preferences. Google Fonts supplies interface typefaces without receiving palette content.

Start with these highlights, then open the complete guide for every capability.
