Foto-Entwerter

Foto-Entwerter (German: invalidate photos or – more literally – remove the value from photos) is a tool to black out faces and license plates from a large number of photos in a manual but efficient way for a large number of photos. It preserves metadata. EXIF thumbnails are not updated.

Dependencies

Usage

Foto-Entwerter is called from the command line. It expects two arguments, the input and the output directory.

In the GUI, you can navigate with your keyboard only:

• A: Switch to add mode. You now add areas to be blacked out by drawing rectangles.
• D: Switch to delete mode. By drawing a rectangle, you delete all blacked areas intersecting with it.
• S: Apply the blurs and save the image to the output directory.
• Space: Switch to next image.
• Backspace: Switch to previous image.
