Data File Compression
The basic definition of data compression is the reduction of the data file (electronic document) size for faster file transfer and reduce the space occupied by the file in the system memory. The number of bits occupied by the data is cut down. Compression is especially useful when applied to large data files to transfer or load easily and faster. The Portable Document File commonly called the PDF is the most preferred format for document sharing, transfer and of course long term archiving. Compression techniques are usually applied to PDF documents which become large when they contain a large amount of high resolution content such as images and videos, or even just a very large number of pages.
What is the Need for PDF Compressors?
PDF compressors help to make very large PDF files easy to handle and work with and save user's time and cost involved. Large PDF files sometimes delay email transmission by failing to attach properly and quickly. Downloading from web pages is very difficult and slow when the file size is huge. PDF compressors are necessary to cut down the PDF size and make it network friendly and easy to handle.
How to Choose Good PDF Compressors
Users wanting to buy good PDF compressors software should go for the product that includes both lossy and lossless compression algorithms. The combination of both types of algorithms helps to customize the type of compression used for a document or batch of documents. To compress PDF as small as possible especially for emailing, user should decide between lossy or lossless compressors depending on whether user can afford to lose a bit of data or not. Next factor to be considered is the cost of PDF compressors. If necessary, additional software options are to be verified. If the PDF has to be text-searchable, then paying for the OCR option would be beneficial.
