Compress Large PDF
PDF files are large because they can carry a lot of data on them. When the file format first came into being, they were considered to be the best and most secure type of file format that any user could use. The files created could be shared and sent to other users without any problems at all. The files were also considered to be secure enough to resist any type of editing or hacking. As a result, almost every user who had data to share and transmit used the PDF format to send information on the internet. But over the years as files increased in size and data content, they became more and more difficult to send over the internet in the form of internet attachments. The files took over twenty minutes to attach and just as much time to download and that was not acceptable.
How the Process Works
Users then realized that optimizing the files for internet use was essential and that was possible if only certain changes were made in how the files very made. After preparing the files for website optimization it became essential to have them compressed for sending over the internet. The process used to compress large PDF files was really simple with several compression algorithms being automatically introduced into the PDF software. But other than the compression algorithms users used website optimization tricks like avoiding the use of bitmapped images and replacing them completely with vector based images. If the use of bitmapped images is really essential then users can ready compress the images and then prepare the files for compression algorithms.
Compression Algorithms Lossy Vs Lossless
There are at present two varieties of compression algorithms called lossy and lossless and they work to compress large PDF files to as small as possible. The lossy alogrithsm were the best as they managed to shrink file size to almost a quarter. But users noted that along with the compression came a large amount of artifacts and distortion of file data. Lossless compression algorithms were better as no problems were noted with the data. But as most of the original formatting and data was retained, the lossless compression algorithms could not achieve equivalent levels of compression as the lossy algorithms.
