What hidden photo data contains
Photos from phones and cameras carry EXIF metadata: the exact GPS location where the photo was taken, date and time, phone or camera model, lens and settings, and sometimes your name or software details. Posting such a photo can reveal your home address, daily routine or the device you use.
How it works
The picture is redrawn from its visible pixels and saved as a brand-new PNG file. Because only the pixels are copied, none of the original EXIF, GPS, camera, software or other source metadata is carried over. Several pictures can be cleaned at once.
When it matters most
Before posting photos taken at home on marketplaces such as OLX or Facebook, before sending pictures by email or file-sharing links, before publishing photos on your website, and before sharing photos of children. Many social networks remove location data automatically, but email, cloud links and many websites do not.
Common problems and how to fix them
The file got bigger: PNG is lossless, so photos grow — convert to JPG with Image to JPG afterwards; the new JPG will also be free of the old metadata. The photo appears rotated: some photos rely on an orientation tag; your browser applies it when redrawing, but check and fix with Rotate Image if needed.
Good habits
Turn off location tagging in your camera settings if you rarely need it, clean photos before sharing publicly, and keep originals private.
