Why Compress PDF Documents?
PDF documents occupy pride of place in today's computing world and this is certainly not surprising given the fact that PDF files offer so much convenience as well as security because it helps in encryption as well as password protection. This has immense utility in archiving as well as document storage and management. This is one reason why around the world, people convert word documents, excel spreadsheets as well as image files of various types into PDF for effective data transmission and storage. PDF files that are too large and unwieldy are not ideal from the point of view of sending mails or even downloading from the net or uploading on servers and data transfer mechanisms. Compressing PDF files and ensuring that files are of an optimal size thus becomes so very important.
Compression of PDF documents is in basically two forms. The first type is lossy compression which is compression that reduces the size of PDF files to a very large extent, maybe as low as 100X. However, there is some loss in the nature of the PDF files in terms of resolution, artifacts and the like, which gets very pronounced in progressive compressions. With each compression, the quality of the PDF gets decreased to such an extent that it can hardly bear any resemblance to the original PDF. The other form of compression is known as lossless compression, which by definition implies compression which involves absolutely no degradation in the quality of the document being compressed. Even though the PDF file is compressed to an extent lesser than the lossy compression, it has high utility in cases where quality loss is sought to be prevented despite repeated compression being conducted.
PDF Compressors Availability
One can avail of PDF compressors online, as well as from retail stores that stock software products. With the demand for PDF compressors being so high, it is quite expected that the number of compressors available would also be quite high. With add-ons and special features being added, companies are able to release proprietary products that people have to pay for, sometimes by using payment gateways that are essentially online modes of payment. Sometimes free trial or demo versions may also be availed of.
