Setting conversion options for image files
You can set compression and color management options for supported image files. The
compression settings are predefined (and unavailable) for JPEG and JPEG2000.
Note: JPEG2000 compression is not backward compatible with Acrobat 4.0. Full object
stream compression is not backward compatible with Acrobat 4.0 or 5.0.
Set the compression to be applied to monochrome, grayscale, and color images:
●
For Monochrome, choose CCITT G4 to apply a general-purpose method that produces
good compression for most types of monochrome images. Choose JBIG2 (Lossless) or
JBIG2 (Lossy) to apply better compression than that obtained with CCITT G4. In lossy
mode, the compression ratios can be several times higher.
●
For Grayscale or Color, choose ZIP to apply compression that works well on images with
large areas of single colors or repeating patterns, such as screen shots, simple images
created with paint programs, and black-and-white images that contain repeating patterns.
Choose JPEG, quality minimum to maximum, to apply compression that is suitable for
grayscale or color images, such as continuous-tone photographs that contain more detail
than can be reproduced on-screen or in print. Choose JPEG2000, quality Lossless, to
apply lossless compression with additional advantages, such as progressive display.
(JPEG2000 is the international standard for the compression and packaging of image data.

Set the RGB, CMYK, Grayscale, and Other color management options:
●
Preserve Embedded Profiles uses the embedded ICC profile from the input file.
●
Off discards profiles from the input file.
●
Ask When Opening displays a dialog box that allows you to choose whether to embed or
discard the ICC profile from the input file. The size of the profile is given.
