Why Learn How to Compress PDFs
Every eBook, report or presentation that we read today is in the form of a PDF or Portable Document Format. This is a universally accepted format for viewing and transferring files among users. PDF is independent of any application or platform thereby eliminating the need for compatible programs between users. A document can be created in any application and converted into PDF and viewed from any PC. Documents contain a large number of images, fonts, styles, and other objects that increase file size. Large files are inconvenient for users to download and view. To reduce file size PDF documents can be compressed to less than half their original size, which is possible with the help of a PDF compressor. Let's look at a few methods and learn how to compress PDFs.
Methods on How to Compress PDF
Pages must be thoughtfully constructed when a document is created. It is best to minimize the use of large images, a variety of embedded fonts, and different styles. Use the `Save As' option to save files as this function overwrites the entire file and saves file space as opposed to the `Save' option which only saves changes made. The other option is to use a PDF compressor. These programs adopt various compression techniques like Flate, Zip, JPEG, and RunLength. Some apply the lossless method of compression in which files retain their original format. In lossy compression there is a slight degradation in the quality of the file. Compressed files can be brought back to their original size through decompression.
Where to Find PDF Compression Tools
The type of PDF compressor you choose depends on your usage. There are various PDF compression tools available online. Commercial brands come with a price tag, although there are several features and add-ons bundled with their programs.

Make sure to test some of them before you finally make your choice. Read through the reviews and check the ratings if you are seriously thinking of buying one.
