The PDF files are generally used for the transmission of data over the internet or in work spaces. The size of the files can affect loading, saving or the transferring of files through the internet or in e-mails as attachments. This will lead to wasted time, money and the work you put in. So it is important to compress the files for maximum reduction of a PDF files size. To make reduction in the file sizes we can compress the PDF file in different ways.
Some of the factors that might affect the maximum reduction of size of PDF files are image type, its resolution, fonts and how the fonts are embedded, the version of PDF and the compression level. These factors have to be considered to enable maximum reduction of size of PDF files. The reduction in the file size, in a large scale, can be brought about by compressing the images inserted in the PDF files. Different types of compression algorithms can be used to reduce the image size and the type of compression algorithm by selecting the quality of the image used. The two major classifications in compression are lossy and lossless compression. The lossy compression will have a higher compression ratio while the lossless will have a lower compression ratio but retains the quality of the image without a problem. The Save option instead of Save As option can be selected to reduce the file size. It will remove the unused items in the document thus making more space in the memory. You can also compress the files by overwriting the existing files.
When the number of PDF files is large, the maximum reduction of size of PDF files can be brought about through batch PDF compression. In batch compression large number of files can be reduced in size. An added advantage in this process is that it can be password-protected, thus making it secure. Different plug-ins that can be used with Acrobat and some software are also available to provide maximum reduction of size of PDF files.
