Color Palette Conversion: UPC

Universal Palette Converter (UPC) helps you move color palettes between formats without rebuilding them manually.

Import palettes from design tools, files, or raw text/code, then export them into formats that work elsewhere.

It’s useful if you’ve ever needed to reuse colors across apps or environments.

Examples:

- For designers: export a palette from Affinity and import it into Procreate
- For developers: copy colors from one codebase and reuse them in another
- From design to code: take colors from a UI file and export them as CSS or JSON
- From anywhere: extract colors from text, a website, or a document and turn them into a usable palette

What you can do:

- Import palettes from common design formats (ASE, ACO, GPL, Procreate, Affinity, Sketch, Corel, and more)
- Extract colors from text or code (Hex, RGB, HSL, CSS, JSON, JavaScript, Swift, Kotlin, XML, Dart, etc.)
- View and inspect colors in multiple formats and color spaces
- Convert palettes between formats
- Export to files for design tools (ASE, ACO, GPL, Procreate, Sketch, and others)
- Export as code (CSS, JSON, JavaScript, Swift, Kotlin, Dart, XML, SVG, etc.)
- Generate palette images (PNG, JPEG) for sharing
