Portable Document Format or PDF is a name that is familiar to most internet users. It is the preferred file format for web users for information exchange. The PDF is preferred since it is platform independent and it is utilizes less space compared to other file formats. Though the format uses less space, the large amounts of data requires more space. Since bandwidth is a precious commodity on the World Wide Web, it is expensive and time consuming. This leads to the necessity of PDF file compression. PDF compression deals decreases the size of the file, making it more suitable for the internet.
PDF compression first condenses the data and makes it into an encoded form with its size lesser than the original. After it is e-mailed, the receiver decompresses it and gets the original data back. PDF size compress tools work by reducing the redundancies in the document. They include multiple spaces, repeating regions, outline areas, etc. The redundancies are eliminated by substituting them with a single character. This is called encoding the data. This PDF size compression tool helps in reducing nearly 50% of the size of the file. The PDF compression tools can be classified as lossy and lossless tools. Lossless techniques dont loss any data during compression and decompression. It can compress only to a limit though, and cannot do so above that. Lossy techniques result in high compression ratio but result in loss of data consistency.
PDF size compress tools are becoming a necessity since more and more data is sent over the World Wide Web. The PDF size compress tools are in-built in most PDF softwares. These tools help in saving time and bandwidth for net users. There are a wide variety of such tools available for the users to choose from. Though these tools are primarily for transmission over the internet, they are also used for storage. There has been advancement in these tools and better algorithms are being developed that enable high compression ratios but still maintains data consistency at satisfactory levels. PDF size compress tools are a must for a regular net user.
