When you add multiple icons to a collection, each unique icon counts as 1 download. This means that if you add 100 icons to a collection and download them all at once (or as a font), it will use up all 100 of your monthly downloads. However, you can download the same collection multiple times in different formats or sizes without any limits.

Keep in mind that collections themselves have a limit of 1000 icons, though we recommend working with fewer to avoid any performance issues.
