Compress PDF files on computer

In earlier posts, we discussed how to convert multiple images into one PDF file so you can easily send and share the images files. Mac users can make use of the Preview app to merge multiple pictures to PDF on Mac without third-party PDF tools. On Windows PC, we can use the Microsoft Print to PDF feature to combine several photos to one PDF on PC.

Sometimes however you may find the PDF file is too big to be sent via email, can’t upload to your website due to large file size, can’t publish to your social network due to the maximum file size limit. In these circumstances, you need to further reduce file size and compress the images and data in the PDF file. Here we’d like to share with you an easy way to achieve that. You will learn how to compress PDF files and reduce file size on PC and Mac using PDF Element, the easy-to-use and yet powerful PDF reader, editor, converter.
