PNG is a lossless image format that supports transparency. It’s ideal for screenshots, logos and graphics with sharp edges, but photos saved as PNG are large. ICO is the icon format used for website favicons and Windows icons. One ICO file holds several sizes of the same image.
Converting to ICO gives you a ready-made favicon or Windows icon with several sizes in one file. The conversion happens entirely in your browser, so your files are never uploaded and there’s no size limit beyond your device’s memory.
How to convert PNG to ICO
- Add one or more PNG files.
- They’re converted to ICO automatically.
