Hi @Tariq
If you want to upload an image to Teams as your profile photo, the image needs to be smaller than 4MB.
Based on your description, the problem may be that the resolution of the image may be too high to be used as a profile picture. Try uploading that copy as your profile picture or lowering the image resolution to see if it's clearer.
According to feedback from forum users, .png images may be clearer than jpg, please try changing the image format to .png.
