Why Do We Compress a PDF File?
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 they have to be compressed using freely available PDF compressors.
Which are the Ways to Compress a PDF File?
There are two broad classifications in PDF compression techniques - Lossless and lossy compression. Using the lossless technique, all original data can be recovered when the file is uncompressed. With lossless compression, every single bit of data that was originally in the file remains after the file is uncompressed and can be completely restored. This technique is best for text or spreadsheet files, where losing words or financial data could pose a problem. The Graphics Interchange File (GIF) is an image format which provides lossless compression. On the other hand, 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?
Information exchange across the network is made faster, easier, and less expensive by compressing PDF files for transfer. 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.
