The Free PDF Compressor helps users to save on their disk space by compressing their PDF files and reducing their size. It does the job in record time and hence, is very efficient. The fact that there is no change in the quality of the resultant file after the compression is yet another advantage. There are two types of compression algorithms which this tool presents and each one has its own features. These are Flate and RunLength. Depending on the system and the user's requirements, one of them can be chosen. Since PDF files are quite huge, this app is very helpful in reducing the space required to save them on your system. The user can compress several PDF files simultaneously, which is another feature that cannot be ignored. This way, the time saved by this Free PDF Compressor is impressive. The status of the compression is also displayed on the screen which makes it easier for the user to keep a check. At any point in time during the process, the app allows the user to stop the compression if need be. The image quality of the compressed file is also an option which the user can choose. Another feature is that it also allows decompression. For any reasons, if the user wants the files in their original size, the same is also made possible with this Free PDF Compressor. It is very simple to use and with a user friendly interface, this app is highly recommended. The only glitch is that the speed of the PC is reduced slightly when the app is being used. Apart from this small issue, there is nothing else that creates any problems for the user. It is free and hence, is a great app for saving disk space on a system.
