Long PDFs often contain only a few pages you actually need - one page of a contract, a single chapter, or a certificate inside a scanned bundle. Extracting creates a new PDF containing only those pages, leaving the original untouched.
Steps
Open the Extract PDF Pages tool and upload your PDF
Enter the pages to keep - for example 1,3,5-7 picks page 1, page 3, and pages 5 through 7
Click Extract and download the new PDF containing exactly those pages in that order
Tips
Check the page numbers shown in your PDF reader - cover pages often shift numbering by one
Ranges can be combined with single pages in any order
The extracted pages keep their original order unless you specify otherwise
To rearrange all pages instead, use Reorder PDF Pages
