Reducing the Size of a PDF File
PDF files are generally extremely convenient for document sharing and storage. However, reducing the size of a PDF file can become necessary if the file becomes too large to quickly transfer, or if it eats up a lot of disk or server space. PDF files can become large as a result of high-resolution content such as images or videos; PDF compression software can reduce the size of a PDF file to make it easy to work with again.
How Reducing the Size of a PDF File Works
Reducing the size of a PDF file is accomplished with PDF compression software. PDF compression software is specifically designed for reducing the size of PDF files, since inconveniently large PDFs aren't all that uncommon. PDF compression software can reduce the size of a PDF file using one of two general methods. These methods of reducing the size of a PDF file are lossy and lossless compression. The lossy compression method reduces the size of a PDF by reducing the quality of the aspects of the PDF that take up the most space. This method can achieve the greatest possible compression, but is not ideal if the full integrity of the PDF must be maintained. If this is the case, lossless compression, which cannot achieve the same amount of PDF file size reduction but results in reduction with no quality loss, is the better choice. Some PDF compression software strives for what is called perceptibly lossless compression, which uses a lossy compression algorithm that does not result in any quality loss that is visible to the naked eye.
