clearheader

ClearHeader

Command Line example

abatchit *.jpg resizemethod=1/2x clearheader (note : remove all image header information such as EXIF and IPTC)
abatchit *.jpg resizemethod=1/2x (note : retain all image header information)

To reduce the image file size, adding the clearheader switch would remove all EXIF and IPTC headers from the images. This would reduce the file size by about 18kb. If you want to keep the the image header information, do not add the clearheader switch.
