Splitting a document in two is usually about a size limit, and it is a better answer than compressing until the text is unreadable.
Illustrative example: extract 1-5 from a ten-page file, save, then extract 6-10 from the original. For odd counts, choose which half gets the extra page. There is no automatic equal-halves control.
Ranges use physical page indices. Nonexistent pages are ignored and repeated numbers are removed.
All content on a kept page remains. Selecting pages is not redaction.
For a document of 20 pages, keep 1-10 for the first half, then run it again with 11-20 for the second. For an odd number of pages, round the first half up, so a 25 page file is 1-13 and 14-25. The page count is shown when you add the file.
The thumbnails help you split at a sensible point such as a chapter break, rather than the exact middle. Each half is a new file named after the original, and the original is not changed.
No. It creates one selected-page PDF. Repeat with another range, or use every-page splitting for individual files.
A PDF that needs a password to open must be unlocked first with Protect PDF. For a very long document the thumbnails can take a moment, and you can still type the page numbers yourself.
Run it three times with a different range each time, for example 1-7, 8-14 and 15-20 for a 20 page document.
