Keeping only the pages you name
You type the page numbers or ranges you want, and the tool copies exactly those pages into a new PDF. Everything else is left out.
The Pages to Extract box accepts comma-separated values such as 1,3,5-8. A range like 5-8 expands to pages 5, 6, 7 and 8. The result is saved as extracted.pdf, and your original file is never changed. The output order follows your input, so typing 4,2 produces page 4 first and page 2 second, and typing 2,2 gives two copies of page 2. That makes it handy for quickly repeating a page, such as a blank form, several times in one file. Whitespace around commas and dashes is fine, so 1, 3, 5-8 works the same as 1,3,5-8.
