About IcoSmith

IcoSmith is an open‑source tool to create sharp favicons from PNG/JPG/SVG — fully local, in your browser.

What makes IcoSmith look crisp

1) Crisp 16–32 px A naïve 1024→16 resize blurs details. IcoSmith uses multi‑step downscaling and adaptive sharpening to preserve strokes and contrast.

2) Private and fast 100% in‑browser (client‑side) processing. No uploads. Instant conversions, no data exposure.

3) Real‑world performance Heavy work runs in a Web Worker so the UI stays responsive. Built with Core Web Vitals in mind.
