A few years ago WhatsApp was allowing WhatsApp Mobile / iPhone / Android and Mac app used to save any contact’s profile photo by clicking on the action sheet button and then tapping save.
But then WhatsApp removed that button.
But somehow one trick works.
Assumption: We assume that you have connected WhatsApp iPhone & Mac apps. You have already added your WhatsApp mac app to your iPhone number by scanning a QR code.
Step 01: Choose any of your WhatsApp contacts.
Step 02: Click on their name or photo at the top header or navigation bar.
Step 03: You will transition to their Profile information i.e. ‘Contact info’ at the right-hand sidebar.
Step 04: Now click on their circular photo again then it will open in the middle full screen.
Step 05: Right-click on the photo and choose ‘Copy Image’.
Step 06: Now open the Preview app from your Mac’s Application Folder and choose File > New from Clipboard
Step 07: Done, Now save your photo to your Mac in PNG file format.
Hope this helps,
Thanks & Regards
