Local · No uploadIICO is the Windows icon format, and it is also the traditional favicon format for websites. A single ICO file is a container that can hold the same image at multiple sizes — typically 16×16, 32×32, 48×48, and 256×256 — so the OS can pick the best fit. Converting ICO to PNG extracts those frames into standard, individually addressable PNG images that every browser and image tool understands.
PNG is the modern favicon replacement for ICO: it is smaller, supports alpha transparency natively, and is supported by every current browser. Migrating an old ICO favicon to PNG (or the SVG + PNG combo) is a standard web-performance cleanup, and extracting the highest-resolution frame gives you a source asset you can reuse for app icons and social images.
When an ICO contains several sizes, the converter exports one PNG per size so nothing is lost — you keep the full set. For most uses, the 256×256 frame is the best source: it scales down cleanly to any smaller icon size you need.

For modern browsers, yes — PNG is smaller, supports transparency, and is widely supported. Keep ICO only for legacy IE compatibility if you need it.
Yes — free, no signup required, and the file is processed in your browser so it stays private.
