Sometimes a photo looks fine on your phone or computer, but rotates after being uploaded. This happens due to the Exif orientation metadata. This article explains the reason and suggests tools to fix it.

Exif (Exchangeable Image File Format) is a metadata standard embedded in image files, storing details such as device, time, aperture, shutter speed, and GPS location. It is useful in photo management, photography learning, and forensics, but may also pose privacy risks.
