Limits: Windows, Android and many websites cannot open it without extra software.
ICO is the container for Windows icons and website favicons, holding several sizes in one file.

Limits: It is only meant for icons, not for large photos.

Yes. Drop as many HEIC files as you like: several are converted at the same time, depending on your processor cores, and when they finish you can download each ICO or all of them in a ZIP.
