Why Should You Reduce the File Size of PDF
For understanding why you should reduce the file size of PDF, you need to have some basic idea about data compression. The technique of data compression refers to the method by which the size of electronic data is reduced. In other words, data compression reduces the number of bits occupied by the data. As PDF files often contain high resolution content like videos and images, or several pages, which in turn increase the size of the PDFs to a great extent - making it necessary to reduce their size. When PDF files become too bulky to handle, data compression is applied to them, resulting in compressed PDFs that require less storage space, load faster, and can be transferred and shared more easily.
PDF Compression Software
PDF compression software mainly uses two main data compression algorithm categories, namely the lossless and the lossy compression method. Lossless compression algorithms find some logical patterns in the data that needs to be compressed and abbreviates them in a manner that enables the same to be reconstructed instantaneously when the user opens the file. As a result, this compression technique does not cause any loss to fidelity. However, with the lossy compression method, you can achieve greater compression rates as compared to the lossless mode, but would need to compromise on fidelity of data. This happens because some inessential data are eliminated from the file by the lossy compression method. Despite this shortcoming, the lossy compression is used in many cases where much greater compression rates are needed and the loss of fidelity is not a reason to worry about.
Choosing the Right Software to Reduce the File Size of PDF
When you want to choose the right software to reduce the file size of PDF, it would be prudent to look for a product that includes both lossless and lossy compression algorithms. Buying such a product will help you to adjust the mode of compression so that you can use the same for either a single document or a group of documents. For example, while reducing the size of a PDF so that you can send it via email, you can select an appropriate lossy method of compression. However, you will need to use the lossless compression mode if fidelity of data is important to you.
