Why the Need to Compress PDF Files?
PDF is most widely used format for storing documents, e-books or other important files. This is because of the convenience it offers in saving, sharing the files between different computers, sending files as attachment and its ability to support different types of data like text, image etc. Most often these PDF files are quite large in size and make it difficult to be saved, shared or attached to emails. Hence the need to Compress PDF Files arises. There are software tools to Compress PDF Files which perform compression as per the algorithms they are designed with.
Compress PDF Files - Selecting the Proper Algorithm
There are a number of algorithms used in tools to Compress PDF Files. Selecting a proper algorithm depends on the file type and the level of compression one requires. Compression algorithms to compress PDF Files are of two types i.e. lossless and lossy compression. Lossless compression algorithms need to be used for files where loss of data or fidelity is not acceptable while lossy techniques can be used where some loss of fidelity is acceptable. Lossy Compression algorithms offer higher rate of compression. Some of the different algorithms used are ZIP, CCIT, RLE, JPEG compression etc. ZIP is used to Compress PDF Files which have repeated pattern images or single color. CCIT algorithm is best for PDF files with textual content or black and white images. RLE algorithm is useful in compressing PDF files which have images of solid black or solid white color. PDF files which contain true color images like photographs can be compressed with JPEG compression.
Software to Compress PDF Files - a Useful Tool for Offices
The tool used to Compress PDF Files significantly reduces the time taken for upload or download of PDF files and hence reduces the waiting time. Some of the tools can even reduce the file size to 100 times. The PDF files thus compressed also require lesser storage space. Such tools are very useful for organizations that deal with a large number of PDF files.
