Color Palette Conversion: UPC

About this app

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 Other details: - Works fully offline - No account required --- Import from: Files: - Adobe Color Book (ACB) | .acb - Adobe Color Book Legacy (ACBL) | .acbl - Adobe Color Swatch (ACO) | .aco - Adobe Color Table (ACT) | .act - Adobe Swatch Exchange (ASE) | .ase - Affinity Designer Palette | .afpalette - ArtRage 6 Color Palette (COL) | .col - Color Exchange Format (CXF) | .cxf - ColorSchemer Studio | .cs - CorelDraw 4 Palette | .pal - GIMP Palette | .gpl | Gimp, Inkscape, Krita, KolourPaint, Scribus, CinePaint, MyPaint - Homesite Palette | .hpl | Allaire Homesite, Macromedia ColdFusion - KOffice Palette | .colors | Calligra Suite, KDE Applications - Paint.NET Palette | .txt - Procreate v1 Swatches | .swatches - Procreate v5 Swatches | .swatches - Jasc / Corel Paint Shop Pro Palette | .pal, .psppalette - Rebelle | .txt, .colors - Resource Interchange File Format (RIFF) | .pal - Scribus Swatch | .xml - sK1 Palette | .skp | sK1 - Skencil Palette | .spl | Skencil, sK1 - Sketch Palette | .sketchpalette - StarOffice Colors | .soc | StarOffice, OpenOffice, LibreOffice Any text containing the following formats: - Hexadecimal color codes - CSS/SCSS/LESS color values and variables - JSON - JavaScript/TypeScript constants - XML/Java/Kotlin - iOS Swift/Objective-C UIColor - macOS Swift/Objective-C NSColor - .NET Color - Flutter Color - Apple Property List (plist) --- Export to: Files: - Adobe Color Swatch (ACO) | .aco - Adobe Swatch Exchange (ASE) | .ase - ColorSchemer Studio | .cs - CorelDraw 4 Palette | .pal - GIMP Palette | .gpl, .gimp | Gimp, Inkscape, Krita, KolourPaint, Scribus, CinePaint, MyPaint - Homesite Palette | .hpl | Allaire Homesite, Macromedia ColdFusion - KOffice Palette | .colors | Calligra Suite, KDE Applications - Paint.NET Palette | .txt - Procreate v1 Swatches | .swatches - Jasc / Corel Paint Shop Pro Palette | .pal, .psppalette - Rebelle | .txt, .colors - Resource Interchange File Format (RIFF) | .pal - Scribus Swatch | .xml - sK1 Palette | .skp | sK1 - Skencil Palette | .spl | Skencil, sK1 - Sketch Palette | .sketchpalette - StarOffice Colors | .soc | StarOffice, OpenOffice, LibreOffice Text: - Color values in various color spaces and representations (Hex, RGB, HSL, etc.) - Web colors (CSS, SCSS/SASS, LESS, JS, JSON) - Tailwind v3 and Tailwind v4 config - XML, Java, Kotlin - Apple formats (plist, Swift, Objective-C) - .NET formats (C#, VB.NET) - Flutter formats (Dart) - SVG Images: - PNG, JPEG - Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ - Privacy Policy: https://projects.albemala.me/privacy-policy/
