Extract, split or delete: which PDF tool should you use?
Choose by the result you need, not by the tool name. These examples use a synthetic 10-page PDF, never a sensitive document.
Keep selected pages
Enter 2-4, 7 in Extract Pages. Separate mode creates two PDFs with 3 and 1 pages. Combined mode creates one four-page PDF. Enter 7, 2-4, 3 in combined mode to keep pages 7, 2, 3, 4: repeated page 3 is included once.
Split into equal groups
Choose Split PDF and set 3 pages per file. A 10-page source produces four files with 3, 3, 3, 1 pages. The final group is kept even when it is shorter.
Remove unwanted pages
Choose Delete Pages when specifying what to remove is easier than listing what to keep. Deleting positions 2-4 and 7 from the 10-page sample leaves six pages.
Before you share
Page positions start at 1 and may differ from printed page labels. Check the generated PDF. Page operations do not promise to preserve signatures, interactive forms or every document feature. The source file is unchanged.
