What is a PDF?
PDF or the Portable Document Format has become the standard file format for transferring and distributing data contained in electronic documents. PDF format is compatible on any computer platform and stable while handling multi page and multiple documents. The design of the PDF is such that it retains the data and contents intact and secure for a very long period, even when used or redistributed.
Need to Shrink PDF
The PDF is preferred over other file formats since it can hold more volume of contents and retain the compact size without altering the contents. However, users often want to include graphics, tables or charts along with data and images in the file. This makes the file size too large to be handled while transferring data. Large sized PDFs are difficult to transfer or download. Hence, PDFs are shrunk to required size so that it can be used for distributing data easily. PDF shrinking also deletes unused contents such as thumbnails, metadata, or duplicated data in the file.
What Methods are Available to Shrink PDF?
PDF shrinking to appropriate size is a task that can be done by using either lossy methods or the lossless methods. Lossy methods are the ones in which data that is shrunk in the PDF cannot be recovered completely. When the original specifications are restored, the contents in the PDF may not be of the same clarity as it was before compression. Shrinking the PDF can also be done by lossless methods which shrink the file completely by archiving the file. When the files are decompressed, the file is available as a whole without any losses, in the same form as it was before compression. Specific software to edit the metadata in the file and while creating a PDF file is available. Specific software to edit the metadata in the file while creating a PDF file is available. Using images in format which occupy lesser space should be used and use of different font styles and colors should be avoided.
