WhatsApp Custom Sticker
If you would like to design your own stickers for WhatsApp, you can package them in an Android app. You will need to distribute your app via the Google Play Store or another mechanism. Users who download and install your sticker app will be able to add your stickers to their WhatsApp sticker picker/tray, and start sending those stickers from within WhatsApp. A separate app is necessary and it will reside on your phone's home screen just like any other app. Stickers on WhatsApp must be legal, authorized, and acceptable. Learn more about acceptable use of our services at https://www.whatsapp.com/legal/#terms-of-service. The sample code provides a simple way for you to drop in your sticker art and build an Android app with minimal development or coding experience needed. For advanced developers looking to make richer sticker apps, refer to the section Advanced Development below. We recommend you create a version of your sticker app for iOS as well to give users of WhatsApp on iOS an opportunity to download your sticker app as well. Sticker art and app requirements We recommend you refer to the FAQ at https://faq.whatsapp.com/general/26000226 for complete details on how to properly create your sticker art. This FAQ also contains a sample PSD that demonstrates best practices for composing legible, rich sticker art. A sticker is an image that has a transparent background and can be sent in a WhatsApp chat Stickers are organized into "packs". Your app can contain anywhere from 1 to 10 packs. Users must explicitly add each pack to WhatsApp one-by-one, so your app should list each pack separately and each pack must have its own affordance to add it to WhatsApp (do not try to create "add all packs" operations). Each sticker pack must have a minimum of 3 stickers and a maximum of 30 stickers Stickers must be exactly 512 x 512 pixels Stickers will render on a variety of backgrounds, white, black, colored, patterned, etc. Test your sticker art on a variety of backgrounds. For this reason, we recommend you add a 8px #FFFFFF stroke to the outside of each sticker. See the sample PSD referenced at https://faq.whatsapp.com/general/26000226 for more details. Stickers must be in the WebP format. Currently, animated WebP or animated stickers are not supported. See the section Converting to WebP below for information on how to create WebP files. Each sticker must be less than 100KB. See the section Tips for Reducing File Size below. Sticker Picker/Tray Icon Provide an image that will be used to represent your sticker pack in the WhatsApp sticker picker/tray This image should be 96 x 96 pixels Max file size of 50KB
