Sharing photos: check the EXIF data before uploading

A photo can contain metadata that is not visible in the image itself. Checking those fields is one step to consider before sharing an original file.

From the moment your phone or camera explicitly clicks the shutter, it records much more than just light and color.

The device writes a detailed "birth certificate" directly into the underlying file. This certificate includes the camera model, exposure settings, and even GPS satellite positioning accurate to within a few meters. For professional photographers, this data is a valuable archive to exchange technical parameters. But for ordinary people selling used items or sharing daily life online, it's equivalent to "streaking" across the internet.

While major platforms like Instagram or Twitter automatically strip some EXIF data when compressing images, if you send the "original image" via file transfer or upload it to forums that preserve raw files, your entire hand is exposed.

Inspect the exported file for the fields you intended to remove. Then inspect the picture itself: metadata removal does not hide a sign, address or other identifying detail visible in the scene.
