How to use
- Keep pages 1 and 3 of widths-3.pdf for widths 200 then 400.
- Keep page 2 of the A4 report for one 595.28-point page.
- Type 3,1 if the wide page should come first. The source stays as it was.
Formula / how it works
Keeping pages 1 and 3 of widths-3.pdf writes a two-page PDF whose widths are 200 then 400. The 300-point page is not in the file. Keeping page 2 of the A4 report writes one page, 595.28 points wide. The order is the order you type. 3,1 would put the wide page first. The source file is not edited. You still have the original.
This is the same copy that the splitter uses for a range, with the label "extract" because that is the verb people use when they want a chapter and not a zip of every page. The splitter's each value is the zip. This page does not zip. One PDF comes out.
A blank box is not "all" here in the sense of a surprise. The field starts at 1,3 so you see the pattern. all is accepted by the parser and would copy every page, which is a long way to clone a file. Type the pages you mean. A password stops the copy. Bookmarks are not carried over.
Pages 1 and 3 of widths-3.pdf come out as 200 then 400. Page 2 of the A4 report comes out alone at 595.28 points. Typed order matters: 3,1 would put the wider page first. The original file is not edited. This download is one PDF, not the zip the splitter builds when you type each. Bookmarks are not copied into the extract.
Extract and delete are mirrors only when you want the complement in the original order. 1,3 kept from widths-3.pdf is the same pair that remains after deleting page 2, and both downloads were 200 then 400. The difference shows up when the typed order is not the original order. Extract follows the typing. Delete never does. The splitter zip is a third shape: one file per page, not one file of the pages you named. Keep the source until the page widths in the download match the pages you thought you kept.
Keeping 1,3 from widths-3.pdf writes 200 then 400. Keeping only page 2 of the A4 report writes a single page 595.28 points wide. If you had typed 3,1 the wide page would lead. The source file is still the three-page original. Open it again if the extract widths are not 200 then 400, or not the single 595.28-point page. Typed order is the only order this page will write, which is why 3,1 is not the same download as 1,3 when the source is widths-3.pdf.
A zip of every page is PDF splitter. Putting two extracts back together is PDF merge.
