In this video tutorial, the focus is on reducing the size of PDF files to make them easier to share. There are three main options for this: adjusting settings while creating a file, saving an existing file in lower quality, or using online tools to compress the file. It is suggested to first try reducing the file size within your PDF viewer app before resorting to external tools. A simple step to reduce size is to resave the file using apps like docHub or acrobat. The tutorial demonstrates this process using a 54-page, 17 megabyte Life and Style Weekly Magazine PDF file as an example. This is necessary for sharing via email as many services have a 25 megabyte attachment limit.
