Every photo your phone takes carries hidden information alongside the picture: the exact GPS coordinates where it was shot, the date and time, and the device that took it. Posting that photo publicly can reveal your home address or daily routine without you realising. This tool strips that metadata out and gives you back a clean image that looks identical.
It is information stored inside an image file, typically the camera model, the settings used, the date and often the GPS coordinates.
Location data in a holiday or home photo can reveal more than you intend once the picture is public.
No. Only the hidden information is removed. The image looks exactly the same.
Some do and some do not, and the behaviour changes over time. Removing it yourself is the safe option.
