However PDF files are considerably larger than the original documents. This leads to slower transfer and uploading especially through slower models. This is where PDF compression softwares come in. PDF compression softwares have the unique ability to size down PDF files making it more transferable and space efficient. Free softwares for this purpose are easily available on the net for this purpose.

PDF compression softwares helps reduce the file size saving both space and time and enabling better organization through the free space generated by the compressed file sizes. PDF compression softwares use LZW, i.e. Lempel-Ziv-Welch techniques helping reduce the file size without harming the quality of the original document. This enables the user to reclaim the original file undamaged both in quality and quantity.
