How to hide images | How to safely edit faces, text, and parts of photos

When looking for a way to hide an image, first decide whether you want to make it look less noticeable or if you want to make personal information unreadable. If you want to make the face, background, and eyes less noticeable naturally, you can use blurring or mosaic processing, and if you want to reliably hide addresses, names, phone numbers, QR codes, etc., use black paint or cutouts.
