  The extension lets users create custom Chrome/Edge themes: upload a background image, automatically match colors, preview the theme live, and download a ready-to-use theme ZIP package.

  Theme Creator for Chrome - GThemes is a simple and powerful Chrome theme maker that helps you create custom browser theme packages directly in your browser.
  
  Upload a background image, automatically match colors from the image, preview your design in a Chrome-style layout, adjust frame, toolbar, tab, text, and accent colors, then export a ready theme ZIP package.
  
  Key features:
  • Create custom Chrome theme packages
  • Upload PNG or JPG background images
  • Automatically generate matching colors from your image
  • Preview your theme before exporting
  • Choose from quick presets
  • Customize frame, toolbar, tab, text, and accent colors
  • Download a ready ZIP package with manifest.json
  • Export manifest.json separately
  • Works locally in your browser
  • No account required
  • No user data collection
  
  How it works:
  1. Open the extension.
  2. Upload a background image or choose a preset.
  3. Adjust the colors or use Auto Colors.
  4. Preview the theme.
  5. Download the generated Chrome theme ZIP.
  6. Unzip the package and load it from chrome://extensions using Developer mode.
  
  This extension is useful for anyone who wants to design a personal Chrome theme, test browser theme ideas, create visual concepts, or build custom Chrome theme packages without editing manifest files manually.
  
  Privacy:
  Theme Creator for Chrome - GThemes does not collect, store, sell, or share personal data. Images are processed locally in your browser and are not uploaded to any server.
  
  Note:
  Chrome does not allow extensions to automatically install generated local themes. The extension creates a downloadable theme package that you can unzip and load manually through chrome://extensions.
