Color Palette Conversion: UPC

The ultimate solution for managing and converting color palettes across various formats.

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
