A photo can carry more than pixels. EXIF data may include the phone or camera model, the time a picture was taken, editing software, and sometimes the location. That information can travel with the file when you post or send it.
What EXIF data can reveal
GPS fields are the part to check first. A location tag can point to a home, workplace, hotel, or the place where a photo was taken. Camera and software fields can also reveal details you did not intend to publish.
Clean a photo before you share it
Open the whyaiai cleaner, add the image, and start cleaning. The result is a new file. Your picture stays the same; the embedded tags are removed from the copy.
Metadata cleaning does not change the visible pixels and does not control labels added by a social network after upload. It gives you a cleaner file to share.
