Quick answer
Splitting mistakes often come from counting cover pages incorrectly, mixing page labels with actual page numbers, or choosing delete when extract is the safer workflow.
Search intent
Answer searches about wrong page ranges, missing extracted pages, and confusion between split and extract workflows.
Steps
- Step 1. Open the original PDF and note the actual page numbers.
- Step 2. Decide whether you need to extract pages or remove pages.
- Step 3. Test a small range before processing a large file.
- Step 4. Open the output and verify the first and last page.
- Step 5. Keep the original file unchanged.
Practical recommendations
Use Extract PDF Pages when you only need selected pages.
Use Delete PDF Pages when you want to keep most of the document.
Remember that printed page labels may differ from PDF viewer page numbers.
Write ranges carefully before starting the job.
