Why Should You Reduce the File Size of PDFs
If you have to deal with large sized PDFs on a regular basis, you must have faced a lot of problem while sharing or transmitting such huge PDF files. Such large PDFs even can't be attached to emails, making it all the more difficult to allow multiple users to work on them. So, it makes sense to reduce the file size of large PDFs to solve these problems. Reducing the PDF file size also enables you to free precious storage place, which can be put to good use in a more profitable way.
What Increases the File Size of PDFs
The main reason for the increase in PDF file size is attributed to the size of images contained in it. Your PDF may also become big in size when it contains a lot of embedded fonts, quite a few line objects (CAD file), redundant thumbnails or metadata, duplicate images, or excessive non-image elements. All these reasons cause the size of the PDF to become too large to be handled without difficulty. So, it becomes imperative to scale down the size by using appropriate methods to reduce the file size of large PDFs.
Methods to Reduce the File Size of PDFs
Most software usually use two methods to reduce the file size of PDF - the lossy and the lossless compression. The lossy method can offer higher rates of compression than the lossless method. However, it compromises on the fidelity of data while achieving such high compression rates. So, some data present in the original file are lost forever when you decompress the files that you have compressed by making use of the lossy compression mode. On the other hand, when you need a compression method where no part of the original content should be lost when you decompress the compressed files, you have to use the lossless compression mode. So, this method is utilized where all that matters is the fidelity of data and the rate of compression isn't much of a concern. You can find many online tools to reduce the file size of your large sized PDFs. Simply look around a bit on the World Wide Web and select the tools that suits your requirements the best.
