PDF size, continued
After determining that I couldn’t see any change in image quality when dropping the ‘image quality’ control in InDesign down from ‘maximum’ to ‘medium’, I’ve gone and generated new PDF files for all the portfolios on my static website.
Based on the before/after sizes with those portfolios, it seems that this change results in PDF files that are from 32% to 37% of the files generated with the control set to ‘maximum’. Yes, you’re reading that right – one third the size, same visual quality.
On a related issue, I ran the shrink-it app by Panic Software (pointed out by Paul Bradforth in the comments). It didn’t result in a reduction in size for the PDF files I generated from InDesign. That might not mean much if you’re using ANY other PDF generation tool.
