What happens, and why

ICO is the format for Windows icons and website favicons. It holds several small sizes, such as 16, 32, 48 and 256 px, in one file. It is needed only for making a favicon. Nobody keeps photographs in it. PNG is a lossless format. Every pixel is kept exactly and it stores transparency. Photographs come out far larger than JPG.

The usual reason to turn ICO into PNG is that whoever receives the file can only open PNG.

The file is opened and converted inside this browser and never sent to a server. PNG is a lossless format, so not one pixel changes. Camera metadata (EXIF) is not carried over, so no location data remains in the result. You can add several files at once.

FAQ

3
Does the quality get worse

PNG is lossless, so the pixels are unchanged. Open the result next to the source and they match.

What happens to a transparent background

PNG stores transparency too, so it is kept as it is.

Where does my file go

Nowhere. The conversion finishes inside this browser, and camera metadata (EXIF, location) is not carried into the result.
