The main objective: size it down

A PDF generally represents a smaller file size than the document it originated from, but there are still ways to size it down. Like any on-page object, the smaller you can get your PDFs, the better it is for your SEO. A slow load time will discourage both users and the major search engines.

• Reduce the complexity: PDFs are only as light as their content allows them to be. When you use multiple fonts, numerous images, graphs and other multimedia content, the weight of the PDF increases

• Lighten objects within the PDF: The images and graphics contained within the PDF count toward its weight, so you should perform the usual steps of resizing and downscaling resolution where you can

• Grayscale it: Just as with images, colour PDFs are larger files. If you don’t need colour, remove it

• Allow for best compression: The default settings on most versions of Acrobat are for print, rather than the web. As printers require far better resolution, this means files saved with those settings are much larger than needed
