I am not sure if this question belongs to this group.
When I take photos using my iPhone then the Photos are usually with .HEIC extension. Now from my iPhone I am able to upload the photos to whatsapp. I am guessing that may be iPhone is converting the Photos to JPG/PNG/etc before uploading the Photo to Whatsapp.
Now I have transferred photos from my iPhone to MAC(Please see the Edit below at the end). When I try to upload a Photo using Web-Whatsapp from my MAC then I am not able to upload .HEIC files as they are greyed out. I can upload .HEIC photos as files/documents in Web Whatsapp but then the photo will be displayed as a downloadable file instead of displaying it within whatsapp chat
What is the solution for this situation? Is there a setting I can use when transferring Photos and Videos from iPhone to MAC, so that I can select to convert .HEIC to .PNG automatically?
EDIT: Earlier, I was importing the photos from iPhone into the
Photos.appin MAC. This is not the right way, if the intention is to just transfer the Photos from iPhone to the FileExplorer/Finder in MAC. For transferring Photos from iPhone to MAC I need to useImage Capture.app. https://discussions.apple.com/thread/7090485
But the question is still valid. Even though I used ImageCapture app to transfer photos from iPhone to MAC, all the Camera photos except screenshots are imported as .HEIC and not .PNG. I am not aware of any setting in iPhone to change the photos automatically to .PNG when transferring to Laptop

photos.app. Then in Photos.app preferences -> Show in Finder I can see the photos. Not sure if there is a better way to transfer photos from iPhone to MAC without using iCloud – firstpostcommenter Jun 23 '20 at 13:40
