PDF files are widely used for their versatility and ability to maintain document formatting across different devices. However, large PDF files can be cumbersome to share and store. If you’re looking to minimize the size of your PDF files on a Mac, you’ve come to the right place. This guide will explore various methods to reduce the file size of your PDFs, ensuring they are more manageable and efficient to use.
