How to Remove Pages from a PDF with C# .NET & More!

Most standard PDF readers (including Adobe) do not enable certain editing options, so users are often left wondering, "How can I remove pages from a PDF?"

The good news is, depending on which software or operating system you are using, there are a few options to help you tackle this common PDF challenge.


In this article, we'll provide step-by-step instructions on how to remove pages from a PDF using a couple of C# .NET methods and on MAC OS.

These methods will help you regardless if you need to cut just one blank page or a whole batch of pages from your document.
