In the following part, let us check how to use this software and this technology to compress PDF. Even if you compress image by 1:100 times, the quality is still good. Now let us check the JPEG2000 compression effect from the following snapshot. By this method, we can reduce 100 times of their original size while maintaining better image quality and text legibility.
JPEG2000 is an image compression standard and coding system, which was created with the intention of superseding their original discrete cosine transform-based JPEG standard with a newly designed, wavelet-based method. VeryDOC PDF Compressor can help you compress color scanned PDF down to the same size as black and white TIFF Group 4 images by JPEG2000 technology.
