PDF files were expressly created for the US Government by Adobe Systems. The Government wanted a file format that was secure to send and receive information and which could not be edited by readers. But over time, the file format was also released for use by civilians. And on the internet, PDF files became really popular. They were regularly used to share information, graphics and illustrations by graphic illustrators and artists to send their clients. As the files were incredibly true to the original, there was also no need to send a hard copy of the work along with the electronic version. At the same time, these incredibly detailed PDF files became really data heavy. They became increasingly difficult to send over the internet and equally difficult to download. Users had to learn how to decrease the file size in order to make them easier to send them over the internet while at the same time retaining the appearance and presentation.
A Few Details on PDF Compression
Learning how to carry out PDF compression is remarkably easy. For example, you can start by reducing the number of fonts present on the PDF file. Each font can occupy as much as 40K of space on your PDF file. Almost every user already has the information embedded on their systems so there is no need to have the same information on your newly created presentation. You can easily remove all of the rarely used fonts to decrease file space. Another tweak to remember is that all PDF files work by appending each edit you have made to the file to the file end. That means every time you edit a PDF file; the PDF file starts to have a long tail that will increase file size. The quick way to reduce this is by carrying out all the edits possible and then saving the file in the "SAVE AS" option.
Methods of PDF Compression
Once you've carried out all the PDF compression possible; take the time to check your PDF file size again by checking the AUDIT SPACE USAGE option. This will tell you how much space is occupied on the file after PDF compression.
