Why is It Necessary to Compress Scanned PDF Files
Scanned PDF documents with an enormous amount of text and images will certainly occupy considerable disk space. If scanned PDF files are being generated on a daily basis, the user's disk space will soon get filled up. Inadequate memory space can cause considerable problems in the system, yet one cannot do away with using PDF to store their files. In such a state of affairs, the best alternative is to minimize the scanned PDF files using compress scanned PDF application.
How is It Done?
Compress scanned PDF application employs a compression algorithm for reducing the size of the scanned PDF file. In compressed form, the file will take up considerably much less space than the original. In fact, it will occupy less than one-thirds the space taken up by the original file. One can store thousands of PDF files in a single compressed folder. By compressing scanned PDF files, one saves on disk space.
What are Methods?
PDF files can be minimized by compressing the content and the image. Content compression can be done by removing all extra space characters, using a single repeat character in place of a string of repeat characters and replacing frequently occurring characters with smaller bit strings. This can reduce the file size by almost half. A program that uses a formula or algorithm works on the files and determines how to compress or decompress data. However, in case of scanned PDF files, minimizing the file means image compression. Compression techniques used on scanned PDF can be either lossy or lossless. Lossy algorithms where some information is lost in the compression process can be used to contract image and audio files, but they are not useful for text and program files since some information is lost in the compression process. On the other hand Lossless compression where all the content can be restored on decompression is an ideal solution for compressing text and program files.
