An ICO file is a Windows icon format that can contain multiple images at different sizes and colour depths within a single file. Browsers typically display the largest available image when loading an ICO as an image source.

Will I get all sizes from the ICO?

Browsers expose only one image from the ICO (usually the largest), so the exported PNG reflects that single image. To extract every embedded size you would need dedicated ICO parsing software.

Is my file uploaded anywhere?

No. The browser loads the ICO file locally, renders it on a canvas, and exports PNG — all on your device without any network request.
