FileSenixAre you interested in getting a compressed PDF while maintaining its quality? Well, there is nothing impossible for modern technology – it is possible to achieve both goals simultaneously.
How does the process work? With the help of PDF compression software, one can significantly reduce the size of a file without compromising its quality in a way. The process includes such actions as the elimination of hidden data (like extra fonts), cleaning up the content and images without destroying them. Such type of compressing is often referred to as "lossless" or "light" compression.
Most images that are inserted into a PDF file have many details, which cannot be noticed by an average person. Thus, the image may be compressed without harming its clarity to a large extent.
As for texts in a PDF file, they are rather easy to compress since they consist of simple geometric forms which will not lose their clarity in the process of compression.
In order to preserve the high quality of a file during its compression, it is better to use "low" or "medium" levels of compressing. Many free online tools and applications provide such settings.
Summing up, it is quite possible to compress a file without losing its quality if it is done moderately.
