      Description

      If you add large images in PDF, the resulting document becomes large. I've added about 80 images in size 2100x2100px in the document, and got about 400-500mb in the PDF file.
      From the document analysis (attached screen shot from Acrobate Pro DC), you can see that zip / flate compression is used for added images. I would like to be able to compress images in a document using jpeg compression (something like industry-standard compression filters). Is there such an opportunity now? Can it be add in the future?

      P.S. RGB and CMYK images are used.

      Thanks.
