A WASTICKERS file contains a sticker pack created by Sticker maker, an Android app used to create stickers for the WhatsApp messenger mobile app. It stores multiple .WEBP sticker files, along with a sticker tray .PNG icon that represents the pack of stickers in WhatsApp. WASTICKERS files also contain one or more .TXT files with metadata about the author and title of the sticker pack.

Sticker maker allows WhatsApp users to create their own custom stickers that can be imported in WhatsApp. Once the sticker pack is imported, the stickers are available to be inserted into messages in WhatsApp. WASTICKERS files are compressed with Zip-compression and they typically contain at least three stickers, which are 512 x 512 pixel WEBP images with transparent backgrounds. Also, the sticker tray icon is a 96 x 96 pixel PNG image. NOTE: You can open WASTICKERS files with Viko & Co Sticker maker. You can also open them with a Zip utility by renaming the .wastickers file extension as .zip.
