As the title indicates, Personal stickers for WhatsApp is a free piece of software which helps you in the process of sending any of your images as stickers on WhatsApp. It should work fine even on lower-spec devices because the app itself has a really lightweight design and it doesn't require too many CPU and RAM resources. As soon as you launch the application, you will notice how simple and intuitive the window layout is.
Inside this section you can check out all of your available stickers that can be inserted in your chats with friends and family. In case there are no image files found on the storage of your smartphone/tablet, the app will instruct you to download PNG and WebP file formats from the Internet to be used as stickers for WhatsApp. Taking into consideration how simplistic this tool is, you shouldn't run into problems even if you're a newbie when it comes to using Android mobile devices.
