![]() By reducing the resolution of these images and choosing an efficient image encoding these files can be dramatically reduced. So even documents that appear to be just text can often be entirely images. Scanners often capture document pages as high resolution images without compression. Pdf size reducer free program pdf#NXPowerLite is able to reduce the size of both types of PDF by resizing images, adjusting image formats and quality levels while removing background or hidden data that isn't needed for normal use of the file. The nag screen makes it annoying to use when batch processing large numbers of files (25+), but it's still better than the watermarks or resolution limits of other programs.PDF files are most often scanned physical documents or documents that have been created entirely digitally often referred to as 'native' or 'born digital' PDFs.
