Why Compress a PDF?
The PDF (Portable Document File) document is the standard file format preferred for document exchange or information distribution. PDF is usually loaded with images and high volume of data when it is used and been revised by users. This increases its size to a very great extent. Large sized PDFs are difficult to attach during emailing and take a long time to download and view because network transmission is bound by protocols and limitations. Compressing before transferring large sized PDF documents should be performed to avoid data transmission difficulties.
How to Compress PDF Documents?
There are two categories under PDF compression techniques - Lossless and lossy compression. Using the lossless technique, all original data can be recovered when the file is uncompressed. This technique is opted for text or spreadsheet files, where user cannot afford to lose any word or financial data in the file. The Graphics Interchange File (GIF) is an example for lossless compression format. The lossy compression reduces a file by permanently eliminating certain information, especially redundant information. When the file is uncompressed, only a part of the original information remains. Lossy compression is generally used for video and sound, where a certain amount of information loss will not matter for most users. The JPEG image file provides lossy compression. Either of the PDF file compression ways could be used to suit the user requirements.
What are the Benefits of PDF Compression?
PDF compression is necessary to make information exchange across the network to become faster, easier, and less expensive. Compressed PDF documents do not use up much of the bandwidth nor take too much space of the system memory. Also, by decreasing PDF file size, the recipient of your email would get the smaller sized file and it would be easier to open or download the attachment and view the file. The main reason for using the PDF is its portability and format retention capability. So users would only want large sized PDF compression to be done without affecting the output quality.
