The PDF Size Problem
With the advent and instant popularity of the platform-independent Portable Document Format or PDF files, exercising caution in its development has become a necessity for providing end-user satisfaction. They were designed primarily with high quality printable outputs in mind, but PDF files have the unfortunate tendency to `bloat up' if one is not conscious about its size. In fact reports show that, if ignored, they sometimes occupy nearly 5000 times more than the space required, creating the urgent need for compression and eradication of unwanted/unused data. Thus, PDF optimization comes into play, generating a faster, bandwidth-saving, and efficient mode of transmission via the web. The files thus optimized are easy on the storage space without affecting its readability.
Solution: PDF Optimization
PDF Optimization follows two steps to deliver a PDF file better suited for storage and transmission. These are compression and linearization. PDF compression works on shrinking the document size by discarding unwanted/unused/redundant data, using vector scaling images, restricting the color schemes and fonts to the standard, built-in ones to avoid embedding, and restructuring the document for better portability via the web. Linearization assists the end-user by structuring a PDF file to display one page at a time even while downloading the rest of the document at the background. PDF optimization endows these documents with higher search engine visibility and chances of being indexed.
Tips for PDF Optimization
On the developer side, PDF optimization becomes an effortless, but conscious procedure. Creating smaller PDF files is advisable than attempting to compress large fully developed PDF documents. During the development stage, careful avoidance of uncompressible, non-vector based images, large number of embedded fonts and font styles, and color modes would be prudent. Using the `Save As' instead of `Save' option overwrites the existing large-sized file with the optimized one, thus avoiding appendage of the changes along with the original. And then, using a PDF Optimization Tool would further compress the file, thus enhancing optimization twofold and furnishing us with a resultant that has greater transmission and downloading speed, bandwidth-saving, economical, good readability and printability, thus assuring all round efficiency and user gratification.
