What is a PDF?
Portable Document File, abbreviated as PDF, is a universally accepted file format for reliable and secure document exchange in the high speed data transmission network. PDF is specifically designed as a data container to contain all the file contents (both text and images) and retain the format intact upon conversion for long term. Almost all documentation applications today involving electronic documents prefer the PDF format for ease of use, data retention and data security.
Why Does a PDF Need to Be Compressed?
Owing to the advantages of the format, usually PDF documents are loaded with lots of graphics, tables or charts which increase their size to a very great extent. Large sized PDFs are difficult to transmit or download. While attaching PDF documents to emails, it takes long time if the file size is very huge and the network bandwidth gets clogged. PDF compression is thereby necessary to reduce the PDF size for easy transmission. PDF compression will reduce the image sizes, remove unused elements and optimize the file for fast web viewing.
How Can You Compress a PDF File?
The internet offers a host of PDF compression software tools which can be employed to compress the PDF size. PDF compression helps in efficient data handling and easier data storage and retrieval. Time and cost involved in the data transmission are saved to a large extent. One of the two compression techniques, Lossy or Lossless methods are chiefly used since both methods help to reduce the PDF size to required level. Using lossy compression PDF is compressed though the lost data cannot be recovered completely. Lossless compression will not reduce the quality of the images but the compression of the file will be lesser than the lossy compression. Large sized PDF documents can also be compressed by using the simple Reduce File Size Command. Select the "Document > Reduce File Size" in the software. PDF compression software tool has to be installed and the output PDF is compressed in size.
