favicon 생성기
The NexVaani Favicon Generator allows web designers, developers, and site owners to generate complete, multi-resolution favicon packages from any logo, icon, or photo. In modern web development, websites require multiple icon sizes for desktop browser tabs (16x16, 32x32), Apple iOS home screen bookmarks (180x180), and Progressive Web App manifests (192x192, 512x512). NexVaani generates all required PNG resolutions and .ICO formats directly in your browser, along with copy-paste HTML meta tags, all with zero file server uploads.

기술 아키텍처 및 실행 방식
Multi-Density Canvas Resampling & ICO Formatting
The tool resamples source artwork across multiple offscreen HTMLCanvasElement contexts matching exact device pixel ratios (DPR). For legacy .ICO format, a binary ArrayBuffer is constructed containing an ICONDIR header, directory entries for each resolution, and concatenated PNG/DIB bitmap payloads according to the Microsoft Windows Icon file specification.
ICONDIR Header: Reserved(2 bytes) + Type(2 bytes: 1=Icon) + Count(2 bytes: N_Images)기술적 제한 및 운영상의 제약
- Source images with complex text or intricate illustrations may become unreadable at 16x16 pixels; simple, bold glyphs produce the best small favicons.
