What Is So Special About PDF Compression Technology?

Well your question is interesting and there are multiple aspects to PDF compression. Data in a PDF file can be compressed in many ways. First there is compression for the images (so JBIG, JPEG, LZW, Flate etc). Then there is compression of the actual PDF stream (simply refer to the PDF reference and it does a good job explaining it). Finally there is optimizing PDF compression, where in addition to pdf data compression, prior to actually performing the compression to the PDF data stream you optimize the data to yield better pdf data compression. What is “optimizing” the PDF data for better compression? Well it can vary depending on the PDF creation software. An example is yielding better compression for images. Instead of simply taking an image and arbitrarily compressing it using JBIG, JPEG etc compression you optimize the image (for example slicing it up into smaller pieces) so that it yields better compression when applying any of the standard image compression types (again JBIG, JPEG etc). So there are multiple aspects to PDF compression technology which may not be obvious. The down-side with taking an image and slicing it up means, you have no clue what the original image was (if you try to recover the image). Hope this helps. This is just a simple introduction - you need to refer to the PDF Reference for the insane details.

Compress PDF: All You Need to Know

What is PDF file type description? (PDF/XPS) PDF = the standard PDF document XPS = the Adobe “X” PDF format. Adobe X PDF is a free PDF creation tool. You don't need an application to create PDF files. (Note: If you are already working with Adobe “Flash” and “AIR” you may have already noticed a change in file extensions for some Adobe “Flash” and Adobe “AIR” videos.) You may have noticed that all Adobe PDFs created before June 2013 had the Adobe “R” or “RC” extension added to the end of their file names. I have been hearing talk for a while about Adobe “RC” format for Adobe PDFs being discontinued. However, there is now a “R2” form of Adobe PDFs available. The main difference between the “R” and “R2” forms is the amount of characters they take up when displayed on screen. If you are creating PDFs in Adobe.
