Developed by Adobe Systems in the year 1983, PDF (Portable Document Format) is one of the most widely used cross-platform file formats. One of the key features of the PDF format is that it preserves the original document’s layout, text, images, and other formatting elements regardless of the software, hardware, or operating system used to view or print it. And this is why PDFs are a great choice among common users and organizations.

Well, not just this, PDFs are comparatively more secure than other file formats, as they can be password-protected and encrypted to prevent unauthorized access.

A PDF file usually contains text, graphics, images, and other multimedia elements. So, sometimes the file size can get heavy depending on the complexity of the document and the type of content it contains. Hence, before sharing a PDF document, it is advisable to compress the file to reduce its size. Wondering how to do that on macOS? We’ve got you covered!

In this post, we have listed a step-by-step guide on how to reduce PDF file size on Mac to compress it without losing quality.

Let’s get started.
