Just as with everything else in CoolApp, stickers are encrypted too. CoolApp has a built-in list of default sticker packs that are available to all users, and we’ll add more stickers over time. You can also create your own custom sticker packs or install sticker packs that you receive from other people.

Who can see my sticker pack?
Anyone that receives a sticker from this pack or anyone you share the link with can view the sticker pack including its Title and Author.

Is my artist name going to be displayed when my sticker pack is shared?
Yes. Make sure your artist name is spelled correctly in order to receive proper credit. You cannot edit a sticker pack after uploading.

Does each sticker need to be a separate file or can I put them all in a single file?
Each sticker must be imported separately and should be on a 512 x 512 px transparent background, preferably with a 16 px margin.

Can I import all the stickers at once?
Yes, click and drag your mouse over each file you would like to select.

Your sticker gets resized to fit your entire image.

Do my stickers save as a draft?
No. Closing the sticker pack creator will not save your stickers as drafts.

Can I delete a sticker pack?
