Hi Rurouni_69!
You'll need to unzip the package first. You can use software like winzip, 7zip and the like for that.
Next, you can choose a size (32x32 or 128x128) to use wherever you want.
If you want to add an unpacked emote in Discord for example, please follow instructions from this link: https://support.discord.com/hc/nl/articles/360041139231-Adding-Emojis-and-Reactions-
Kind regards,
Rabosion
