The most thorough cleaning method (using ExifTool)¶

For complete removal of metadata, ExifTool is the most powerful option. First, you’ll need to install it on your computer. Once installed, open your terminal or command prompt.

To clean a single file, type:

exiftool -all= -overwrite_original yourfile.jpg

To clean all files in a folder:

exiftool -all= -overwrite_original /path/to/folder/

This will permanently remove all hidden data from your files.
