The default settings for PdfCompressor, both in Quick Run and Full Options modes, utilize the JBIG2 compression filter. JBIG2 is a recently-approved ITU black and white (aka bitonal) compression standard that allows for much more efficient coding of black and white scanned documents. More information on JBIG2 is available at http://www.jbig2.org and http://www.jbig.org. JBIG2 compression can be up to 10x smaller than TIFF (G4). We recommend the product default settings of JBIG2 in perceptually lossless mode. The perceptually lossless mode, which differentiates the PdfCompressor product from variations that are either lossless or lossy, obtains very compact JBIG2 image streams with no loss in image quality and no OCR degradation.
