Removing pages by number
List the pages you do not want, as single numbers or ranges, and the tool saves a new PDF made of every other page in its original order.
The Pages to Delete box accepts comma-separated entries like 1,3,5-8,12. A range such as 5-8 covers pages 5 to 8. The result downloads as deleted-pages.pdf. Only one PDF is processed per run, and the source file itself is never altered. Because the tool writes a fresh file, you can safely try a list, look at the result, and run it again with a different list if you got a page number wrong.
