PDF Metadata

Applicable to PDF documents.

PDF documents typically contain document information and XMP metadata. In addition, due to performance considerations, deleted objects are sometimes left in the file and only marked as deleted. Although this makes them invisible when viewed in a standard PDF reader, it is still possible to retrieved them from the file.

There are several versions of PDF files. Currently, DataDistiller™ Engine can remove hidden data from some of the PDF versions, which are the most commonly used.

JPEG Metadata

Applicable to JPEG images.

JPEG images may contain the following types of hidden data: EXIF (Exchangeable image file format), IPTC Information Interchange Model, XMP (Extensible Metadata Platform), comments, and ICC Profile. JPEG may contain additional non-standard proprietary hidden data.

JPEG metadata are added automatically by digital cameras, scanners, and image processing software. This metadata often contains information such as the exact date and time the photograph was taken, the digital camera manufacturer, model, and unique serial number, the camera settings, and the location (if GPS-enabled camera was used). Furthermore, a thumbnail of the image often exist in the JPEG file, and many image manipulation software fail to update this thumbnail when the original image is modified. So even if the image was cropped, or otherwise modified to hide certain parts in it, the removed parts may still be visible in the thumbnail.

DataDistiller™ Engine can remove metadata from JPEG files without degrading the image quality.
