About PNG to ICO
Websites use an .ico file as their favicon, the small picture in the browser tab, and Windows uses the same format for program and folder icons. One .ico file holds the same picture at several sizes, so it stays sharp wherever it appears.
This converter draws your PNG at 16, 32, 48 and 256 pixels and packs all four into one file. Transparent areas stay transparent. Start from a square image for the best result: other shapes are centred with empty space around them.
To use the icon as a favicon, name it favicon.ico and put it in the main folder of your website, or link to it from your pages. Browsers pick the size they need: 16 or 32 pixels in tabs and bookmarks, 48 pixels on Windows, and 256 pixels for large icons.
For the clearest small sizes, start from a simple, bold design: thin lines and small text disappear at 16 pixels. A PNG of at least 256 by 256 pixels gives the sharpest large icon.
