Need to Compress PDFs
PDF files have such great usage in contemporary times. When Adobe released Portable Document Formats (PDFs) in 1992, hardly anyone would have guessed that in less than a couple of decades, these would gain such inimitable acceptability and wide spread usage. This is not surprising actually as PDF files bring about a great deal of security and safety in terms of data encryption as well as password protection which is necessary for safe storage and transmission of files. While PDFs are created in various formats, from word, excel or power point and a number of image files, the file sizes could be quite varied too. Large size files may get created based on the nature and type of source files from which they have been created. This calls for PDF compression as it helps in more effective data storage as well as transmission. Too large files would lead to clogging of networks as well as inability to deliver files to intended recipients.
How to Compress PDFs
PDFS can be compressed by using PDF compressors, a number of which are available online. There are both proprietary as well as free trial versions of PDF compressors which one can use. PDF compressors make it possible for users to take uncompressed PDF files as the input, apply PDF compression software to the same and get compressed PDF files as the output. These are also quite simple to use as end users do not required any prior knowledge of programming in order to complete PDF compression. PDF compressors can be as effective in reducing the size of file sizes to the extent of 100 X in the case of advanced software.
What Do Compressors Do?
Compressors have algorithms which are able to remove redundancies and get rid of extra characters, heavier than required fonts as well as graphics or animation aspects that add to file size. In some software options, it is also found that PDF compressors are able to replace strings of characters with simple and single codes so as to reduce file size and also tackle unnecessary metadata in order to compress PDFs. Many of these advanced are mostly found in proprietary software options rather than in freeware.
