How to Compress a PDF on Mac — Free, No Upload
Reduce PDF file size on a Mac in your browser. Choose a target such as 1MB or 2MB, keep files local, and download the smaller PDF.
On a Mac you can reduce PDFs in several ways, including built-in Preview. Tuko is useful when the requirement is specific—such as “under 2MB”—because you can choose a target size and see whether the result actually reached it.
Tuko vs Preview
Use Preview when you simply need a smaller copy and are comfortable choosing an export filter. Use Tuko when an upload portal gives you a hard limit and you want automatic attempts against a specific target size.
