ABBYY FineReader supports the following compression methods:
ZIP is a compression method suitable for images with large areas of the same color (e.g. screenshots). ZIP is a lossless method, i.e. it
does not affect the quality of resulting images.
JPEG is a compression method that is usually used for grayscale and color images, such as photographs. The JPEG is a lossy
compression method which can greatly reduce the size of an image file. However, the image may appear blocky and acquire a
mosaic look, and some shades of color may be lost.
CCITT is a lossless compression method most appropriate for blackandwhite images which were scanned or created with a
graphics application. CCITT Group 4 produces good compression for most types of images. CCITT Group 3 is used in fax
machines.
Packbits is a lossless compression method suitable for scanned blackandwhite images.
LZW is a lossless compression method suitable for graphics and grayscale images.
