Putting a squeeze on your PDF

Techniques to reduce PDF file size and the impact on document content

There are many ways and tools to make a PDF. However, sometimes the resulting document may take up significantly more disk space than you would expect based on its content. It therefore makes sense to try to reduce the size of such PDFs, while preserving the quality of your documents. The goal of this talk is to provide an overview of the range of PDF compression and optimization techniques, and the impact they can have on documents. We will discuss the following topics:

• data and structure removal;
• compression and content stream optimization;
• image resources optimization;
• PDF font optimization.
