•Twemoji Library: Uses Twitter's open-source emoji SVG library (3600+ emojis). Ensures consistent emoji appearance across all platforms. Emojis are loaded from local files first, then CDN fallback
•Canvas Rendering: HTML5 Canvas API with high-quality image smoothing. SVG emojis are converted to raster images at each size. Antialiasing enabled for smooth edges
•Transformations: Scale uses ctx.scale() (50-200% range). Rotation uses ctx.rotate() (0-360° range). Border radius uses ctx.clip() with rounded rectangle path. All transforms applied before drawing emoji
•Padding System: Padding size scales proportionally to output size (base size 512px). Padding color fills the space between emoji and edge. Transparent padding shows background color
•Category System: 9 categories from emojibase-data library. Group 0 = Smileys (169), Group 1 = People (386), Group 3 = Animals (159), Group 4 = Food (131), Group 5 = Travel (218), Group 6 = Activities (85), Group 7 = Objects (264), Group 8 = Symbols (224), Group 9 = Flags (270)
•Search Algorithm: Filters emojis by name and keyword tags. Case-insensitive matching. Example: 'heart' matches ❤️💙💚💛 and 'love' matches ❤️💕💖. Real-time filtering as you type
•Live Preview: Every change triggers instant re-render. No Generate button needed. Preview updates in under 50ms on modern browsers. Shows 16×16, 32×32, 48×48 simultaneously
•Privacy: 100% client-side processing. No emoji images or settings uploaded to servers. All rendering happens in your browser using JavaScript. Your data never leaves your device
•Export Formats: ICO (multi-layer containing 16×16, 32×32, 48×48), PNG (transparent background support), site.webmanifest (JSON), browserconfig.xml, html-code.txt, README.txt
•ZIP Packaging: Uses JSZip library for client-side ZIP creation. All 31 files packaged in browser memory. No server-side processing
