OneDrive for iPhone does support TIF images, but there may be some compatibility issues with certain TIF files. It's possible that the TIF files you are trying to view on your iPhone are not compatible with the OneDrive app. However, OneDrive for Android should be able to display TIF images without any issues. If you continue to experience problems with viewing TIF files on your iPhone, you may want to try converting the files to a different format or contacting Microsoft support for further assistance.
Hi billbremer,
Thanks for writing us here in Microsoft Community.
I understand that you are having issues with viewing TIF images with OneDrive on your iPhone. I checked it in my end and it appears that we are experiencing the same.
With that being said, I expanded my research and exhausted all my resources to get the answer to this question. Unfortunately, OneDrive for iPhone does not support TIF images at the moment. This means that you cannot upload or view TIF images on your iPhone using OneDrive. The reason for this limitation is that TIF images are not widely supported by iOS devices and apps. iOS prefers JPEG or PNG formats for images, which are more compatible and efficient. Therefore, OneDrive for iPhone follows the same preference that iOS prefer and does not support TIF images. However, OneDrive for Android should be able to display TIF images without any issues.
We apologize for any inconvenience this may have caused you. We are always working to improve our app and add more features and functionality. We appreciate your feedback and suggestions on how to make OneDrive for iPhone better. Thank you so much for using OneDrive.
Hope you understand.
Sincerely,
Froilance T.
