What is compression PDF softwarePDF compression is useful when you have PDF files that are too large for e-mail. Most web-based e-mail applications have attachment limits set at 5 or 10 MB. These limits should not be a problem on most occasions for a PDF, but sometimes a PDF is filled with images and graphics making compression of PDF files a necessity. Compression of PDF files can be done through a couple of methods, so selecting the best method is important.
Compression PDF methodsCompression of PDF files is performed through the following methods: lossy and lossless compression. Lossy compression is great for compressing the PDF to a very small size, but it will reduce the quality of any images and graphics within the PDF. These compression PDF methods usually result in a JPEG, GIF or JPEG2000 file. If quality is not important, than this compression method is the optimal choice. Lossless compression methods guarantee the quality of the file and everything found within the compressed PDF, but the file size will not be as small as a lossy compression. The compressed PDF might be enough to fall under the limit of the attachment size.
Where to find compression PDF softwareSoftware for compression PDF can be found mostly online. Many sites offer free or trial based software. These types of software a good to get an understanding for what they do and how it suits your needs, but if you plan on using it extensively, a paid compression PDF program would be the best idea.
