What is typical PDF file size?
There is no such thing as typical PDF file size. The size can vary significantly based on the contents of the document, depending on whether the file contains text, images, or a combination of both. One of the great things about PDF files is that they can support many different types of content. In general, PDF files containing images, especially high-resolution images, can be very large.
Why might it be necessary to shrink a PDF file?
Because some PDF files are too large to send as attachments over email, or to upload to a website, it is best to reduce the file to a more manageable size. However, it is important to be able to do this without affecting the image itself, because the quality of the image should not deteriorate in comparison to the original. Fortunately, PDF supports lossless compression algorithms, which can reduce file size in this way.
