The PDF File
The PDF or Portable Document Format is a container for diverse content. The files look like the original documents and preserve the source file information -- text, drawings, video, 3D, maps, graphics and photographs, -- regardless of the application used to create them. This is a format for capturing information from a variety of desktop publishing applications. The recipients at the other end are also able to view these formatted documents on the monitor or printer, as they were intended to by the sender. This information can also be shared with anyone and it is in prolific use by individuals, organizations and government departments, all over the world.
Why Compress PDF?
Though the PDF format is secure and easy to transfer, sometimes it may be just too large. The PDF file may contain excess of images, graphics, heavy fonts and video. Then there could be a need to compress the PDF file before it is transmitted. There are several compression tools available for this purpose. These compression tools are software programs design to reduce the PDF file to a manageable size, so that it can be used for various applications.
The compression software reduces the PDF file by compressing the images, text and graphics. The software also removes the unnecessary elements in the file, like unused images, metadata, bookmarks and others. The current software uses the latest in image compression technology and formats to make the most compact and web-friendly PDF files. Maximum data retention is also ensured despite the high compression. Compression could be of two types, one is where the reduction is high but there is a loss of quality especially of images and video. Then there is the other type where the content quality would be retained, but the file reduction would not be as much as the former. Software to compress the PDF file is available in several versions on the web and can be easily accessed and used as per the requirement. Quite a few of these software tools are freeware or can be evaluated on a trial basis. Here one can try out the particular software and if found suitable, it can be bought online.
