What gets removed
- JPG: EXIF and XMP (APP1), IPTC/Photoshop (APP13), APP12 and comment segments. The colour profile (ICC) and JFIF header stay so colours look the same.
- PNG: eXIf, tEXt, zTXt, iTXt and tIME chunks.
- WebP: EXIF and XMP chunks.
The sample photo includes made-up metadata and a GPS position so you can see a “before” without using your own pictures.
Why it matters
GPS coordinates in a photo taken at home point to your front door with a precision of a few metres. Serial numbers can link photos to the same camera. Stripping this before posting on forums, marketplaces or sending originals by email removes information you probably didn’t mean to share.
