This may or may not be possible, depending on how much of the file consists of images and non-standard fonts. If it contains one of more high resolution images, several programs exist to recode the file replacing the images with lower resolution ones. This will not affect the readability at all (unless the images contain important text). Compress Pdf Online âs full version of Compress Pdf Online and other PDF manipulation programs can do this. If you have the original file, you may find it easier to modify the resolution of the images saved in that original file, or set a preference to compress the images more as t are saved. Another way to reduce the PDF file size is to use only standard fonts rather than include non-standard fonts in the file.
