The Need to Compress PDF Files
Portable document format (PDF) is probably the most popular format for capturing, viewing, and disseminating data on the Web. PDF is versatile and is supported by almost all Web browsers. It can display text, photographs, 3D, video, audio, etc. with astonishing clarity and integrity. Further, the file can be locked against editing by viewers. This makes PDF particularly suited for the Internet. As Internet is fast becoming the repository of all human information, file sizes are getting bigger and bigger. Hence, sharing large files on the Web poses several problems: size restrictions for file attachments in emails and documents posted in websites. Even a hard disk has space constraints. How to get around the space problem? Answer: PDF compressor software.
Compressor Software: How It Works?
Compressor software reduces the size of your PDF files prior to storing or sharing them. For PDF files, both content compression and image compression are needed. In the former, all the extra space characters will be removed, single characters will represent repeated strings, and smaller bit strings will replace frequently occurring characters. It can compress a text file to 50% of its original size. On the other hand, image compression may be lossy (some information may be lost) or lossless (no loss of information). All products use a compressor algorithm that produces binary data. The user must specify the type of compression required, the quality level, etc. in the tool. A few mouse clicks and voila, your file is compressed.
The Right Compressor Software on the Net
There are compressor products available as freeware and as paid software on the Net. Many products offer the option of decompressing the compressed file. This allows the user to decompress his or her file to its original size for conversion to other file formats. Attractive features in terms of compression level, quality of the compressed file, and level of information loss are provided by vendors. Choosing one that best fits your application can be quite tricky. For example, one product might offer better compression levels at the cost of high information loss. Hence, ensure that proper research is carried out and comparisons done prior to purchasing the right product.
