More about the Compress PDF
Most of a PDF's file size usually comes from its embedded images, a high-resolution scan, a batch of photos dropped into a report, rather than the actual text, which barely takes up any space at all, so real compression means re-encoding those images down without pushing the reduction far enough to blur a scanned page or make an embedded photo start looking degraded. This tool reduces a PDF's file size by compressing its embedded images and removing redundant internal resources, staying inside the range where the document is still practically usable. Useful for shrinking a scanned document down small enough to email when the original file is too large to attach, compressing a PDF full of embedded photos without the images turning visibly blurry, or reducing a report's file size for upload without the text itself losing any clarity.
