WhatsApp Messenger is definitely the most used chat and file sharing application, both by individuals and by companies.
For Android it's been in tests for some time WhatsApp Business. An optimized version for the communications needs of companies and customers / collaborators.
Besides the many possibilities of sharing pictures, documents, locations, etc., in WhatsApp we have the urge to set up a status accompanied by a “profile picture". Usually, the profile picture is a successful selfie, or a logo for business accounts. What you need to know, however, is that not every picture looks good in profile. It must meet certain dimensions in order to be seen well in both friends' contact list and in info account. Where the picture is seen in great size.
Whereas profile picture on WhatsApp appears in two formats: on the round in your friends / chat list and on the square on "info", we will have to take into account both formats when editing a profile picture.
Optimal dimensions for WhatsApp profile picture - WhatsApp Size Profile Picture
The best way to see what your profile picture looks like on WhatsApp before you set it up and make it visible to all your friends Contacts, is to draw a circle over the picture. The optimal format is 1: 1 (square / sqare), and the larger the size, the clearer the picture will be at "Contact Info".
By optimizing the picture, you will know what it will look like in both groups, contacts list, chat message as well as in full size in "Contact Info".
As a photo editing program, we warmly recommend Adobe Photoshop or Lightroom. You will get quality pictures that will be appreciated on social networks. Facebook, Instagram, WhatsApp, etc.
