weddingsue Posted November 16, 2021 Posted November 16, 2021 The AFPUB file of my brochure is 27MB, when I generate the PDF it comes out as a huge 203MB using a resolution of 192px. I don't really understand why the PDF is so much bigger. The brochure has a lot of images in it, how do I reduce the size of the PDF without compromising on the image quality Quote
weddingsue Posted November 16, 2021 Author Posted November 16, 2021 This is going a bit over my head - I thought you only got 16 bit images if you shoot photos in RAW format? The pictures in the brochure are either photos shot in JPG or photoshop files which have been saved as jpgs. The odd thing is that I have just changed a few pages of the brochure by replacing some old images with new ones (approx 15 images) and the size has shot up from 43MB to 203MB. I think I must have missed a setting in the export bit. I have ticked downsampling above 120 and JOG compression. Is there anything else I should set? Quote
weddingsue Posted November 16, 2021 Author Posted November 16, 2021 The DPI on the document is set to 300. Is this too high? I dont want the images to appear fuzzy. Quote

I'll have a test run to confirm this, but if you have lots of images cropped this way, this could explain the problem at least partially.

If linked then I think they will not contribute much to the size of the afpub file but will make the PDF export much larger.

weddingsue Posted November 17, 2021 Author Posted November 17, 2021 actually that is a good point all of the images are linked. Quote

I am talking about comparing the size of the afpub file to the size of the PDF export file. If the former has a lot of large linked images in it then its size would be much smaller than the export, would it not?

hart_art Posted May 27, 2022 Posted May 27, 2022 Instead of exporting to a PDF, which does create a huge file, try going to 'Print' and then print to a PDF (a feature in Windows, or you can download free apps to create this option.). I've done this with another program, and have gotten a much smaller file. eg 40MG instead of 200+MG. Adam Mierzwa 1 Quote
