Presentation, PDF Days 2016, Berlin

As the uses of the PDF document format have extended in diverse areas, the need for optimizing PDFs for different purposes is more important than ever. In this talk, we show in what ways PDFs can be optimized, with and without affecting their visual appearances.We cover topics such as PDF objects optimization, font and font files optimization, image optimization including MRC (mixed raster content) optimization. Finally, we show some real-world examples and show where the fundamental limits of file-size optimization for PDFs are.

Presentation, PDF Technical Conference 2015, San Jose

If you can’t open a PDF file because it is bad or damaged is an unpleasant experience. The presentation introduces the audience to the cause and the art of repairing damaged PDF files. Optimization is more than just compressing images and reducing the size of a PDF file. It can also be used to prepare a document for a specific purpose such as web publishing or printing. The presentation gives an overview of the most common optimization tasks.

Digital born PDF/A – tough nut or (un)recognized potential?

Scanned documents have been archived successfully in PDF/A format for more than six years. However, the attitude towards archiving digitally created documents is more reserved. What are the reasons? Some are obvious: scanned documents are easier to convert into PDF/A format, whilst converting digitally created documents usually represents a technical challenge. Slightly less obvious are errors in the reproduction of the converted document, functional limitations of the PDF/A standard, and other reasons. However, these challenges can be overcome with the right strategies.
