EasyPhpWipeJPG is a script to remove all EXIF, IPTC, and comment information from JPEG images. The resulting image will be 100% identical to the original image without any quality loss (binary wipe). Why shoud you remove EXIF, IPTC & Comment information? For privacy considerations (the image might contain sensitive data (camera brand, model, GPS location, etc.)), SEO considerations (unwanted tags from manufacturers like "LEAD Technologies Inc. V1.01"), and to reduce file size. It offers the option to create backups of the original images, which you may restore or remove later. It can work on images in a single directory, or it can search and include images from the entire subdirectory structure. The images will be processed in batches (no limit to the amount of images).
