Remove the pages a PDF should not have — blank scans, a fax cover sheet, the page that went in twice.
The tool builds a fresh PDF containing only the pages not listed, in their original order and quality — deletion is exact, nothing is re-compressed. At least one page must remain; the tool checks the list against the real page count and refuses lists that fall outside it rather than producing a broken file.
How are page ranges typed? Commas separate entries and a dash makes a range: '2, 4-6, 9' removes pages 2, 4, 5, 6 and 9. Page numbers count from the front of the document as shown in a PDF reader.
Can deleted pages be recovered? Not from the new file — save it under a new name (the tool does) and keep the original until the result is checked.
