PDF files are commonly used for guides and manuals. They are often uploaded in e-mails and onto websites. The file size of multiple PDF files can be large if there are many pages and images. Compression is always a viable choice if you are going to be e-mailing the PDF. Compression makes the file size smaller so that the files upload quicker. If you have multiple PDF files, you can compress them all together in the same folder.
Navigate to where your PDF files are stored.
Hold down the "Ctrl" key and left-click one PDF file. This highlights the file.
Continue holding down the "Ctrl" key and left-click each PDF file you want to zip. Let go of the "Ctrl" key once all the PDF files are highlighted.
Right-click on any of the highlighted PDF files and select "Send to," and then "Compressed zip folder." All of the highlighted files will be sent to the compressed folder.
