This may or may not be possible, depending on how much of the file consists of images and non-standard fonts.

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.

It is not feasible to reduce the PDF file size by using a high compression setting to get the best compression ratio in the PDF for all the documents involved in the analysis. PDF files are commonly up to 5 times smaller than the original documents when compressed by all available compression programs. Using both compression or decompression options of a PDF file is not recommended, as compression settings reduce the file size and quality and may cause further problems or data loss, and decompression settings cause additional quality deterioration and data loss. The standard PDF document is always best used for compression, and the decompression setting for PDF files should be determined by the best compression ratio for the PDF. The following table lists popular PDF compression programs, where the original file is shown as the file. Use a compressed PDF and PDF with a maximum read size of 80.
