Web Asset Generator

Generate favicons, app icons (PWA), and social media Open Graph images from logos or text

What is it?
A comprehensive tool for generating professional web assets from a single source - whether a logo image, text slogan, or emoji. Creates complete favicon sets, PWA app icons, and social media Open Graph images for all major platforms (Facebook, Twitter, LinkedIn). Transforms a single input into all the icons and images your website needs, with built-in validation, accessibility checking, and framework-specific integration code.

How to use it?

The skill uses Claude's interactive visual UI for a streamlined workflow:

*
Select Asset Types - Visual selector for what you need: favicons only, app icons only, social images only, or everything

*
Provide Source - Choose your input method:

  • Upload an existing logo/image
  • Generate from text/slogan with custom colors
  • Use curated emoji suggestions (60+ organized by industry)

*
Generate & Validate - Skill automatically:

  • Generates all required sizes (16×16 through 512×512)
  • Validates file sizes and dimensions
  • Checks WCAG contrast compliance for accessibility
  • Creates PWA manifest.json with proper configuration

*
Framework Integration - Automatically detects your framework (Next.js, Astro, etc.) and offers to add HTML tags to your code

*
Test - Provides validator links (realfavicongenerator.net, etc.) for final verification

No manual image editing required - from single input to complete asset set with validation and integration code.

Key Features

  • Complete asset generation - Favicons (16×16 to 96×96), app icons (180×180 to 512×512), social images (1200×630, 1200×675)
  • Multiple input methods - From images (logos), from text (with custom backgrounds), from emojis (60+ curated suggestions)
  • Interactive visual UI - Question-based workflow using Claude's AskUserQuestion for clear, fast selections
  • Comprehensive validation - File sizes, dimensions, formats, WCAG contrast compliance for accessibility
  • PWA manifest generation - Auto-generates manifest.json with icons, colors, and app settings
  • Framework auto-detection - Detects Next.js, Astro, etc. and provides framework-specific integration code
  • Emoji library - 60+ curated emojis organized by industry (tech, food, commerce, creative, data)
  • Testing validator links - Provides URLs to test your generated assets in real scenariosView on GitHub
