What Do You Mean by PDF Compression?
Portable Document File, commonly called PDF, is a secure and efficient file format for document viewing and exchange. Information storage and retrieval are faster while using PDF. Extremely large sized PDF files are difficult to handle and transmit; hence they are compressed using PDF compression algorithms which remove useless objects (duplicated or unused), ASCII filters, thumbnails, and replaces LZW compression with the superior Flate (even on inline images), among other optimizations. Compression refers to reducing the PDF size to required level. By default it retains all information which cannot be regenerated. Further space savings are possible by setting command line options to remove various unused objects as well or to apply lossy image compression such as JPEG.
How Compact Compression of PDF Useful?
By design the PDF documents are compressed internally to restrict the file size without harming the contents and formatting. However when the PDF is loaded with charts tables, images and high volume of data, its size increases to a great extent. PDFs which are huge in size are difficult to attach during emailing and take a long time to download and view. Compact compression is the software which can perform additional compression of the PDF to reduce the file size further. Compact compression can give 30% to 60% more compression than the PDF compression algorithms.
What are the Advantages of Compact Compression of PDF?
Compact compression of PDF helps in reducing the PDF size further making it easy to handle multiple documents at the same time. Attaching such super compressed PDFs to emails is faster and easier. No information is lost in obtaining the additional compression. The PDF viewer in the browser and all tools including full-text search are compatible to work with compact compressed PDFs. You can archive PDFs in this format and if you need to read them in other PDF viewers, you can always convert them back to standard format by re-running the tool.
