People who mainly use PDF to store files must know that these files occupy large space amounts of space. PDF files are large mainly because of the font and graphics used in them. This is a problem mainly for big organizations which depend on PDFs for file storage. This trouble can be overcome by PDF compression. PDF compression is a compression in which the larger data in the PDF format can be stored in fewer bytes. This compression is essentially compression of the images in the file as they account for the most of the file size. If not compressed these PDF files are difficult to handle as they cannot be easily transferred from one system to another, even through e-mail. There are many PDF compression software tools which help achieve this purpose. PDF compression software is a program which compresses files using an algorithm which determines how to compress and decompress information in the files. With the help of one of these PDF compression software one can easily compress large numbers of PDF files and help you to save disk space and transfer files easily. The original file can be obtained by decompressing. There are two types of compressions done by PDF compression software:
1. Lossy compression
2. Lossless compression
In lossy compression a greater compression ratio can be achieved, but at the cost of losing selective information permanently. This type of compression is not suitable for compressing text material. This gives way to the second method, lossless compression. In this type, the original file can be obtained as it is without any loss of information upon decompression.
Good PDF compression software should give you the compressed format with minimum loss in quality. The compressed format should contain all the traits of the original file. The compression process is carried out by a high quality compression algorithm. The software must have an easy to use interface which can be understood by all users. Thus the software must have very simple easy to follow steps which help compression of a large number of files simultaneously. Without the help of these PDF compression software we would have to look for expanding our disk space, but this software has made our jobs simpler.
