Insert blank pages into a PDF

What this tool does

• After every page, after the ones you tick on the thumbnails, at the start or at the end.
• One or several pages at each spot: two of them make a double-sided divider.
• The blank page takes the size of the page before it: an A4 in the middle of an A5 document shows up too late, at the printer.
• Never a blank page after the last one with “after every page”: nobody asks for that, and it makes a file look damaged.
• The screen says in advance how many pages the finished document will have.

What it does not do: A blank page is an EMPTY page, not a printed divider: nothing is written on it, no number, no section title. If you then number the document, they will be numbered like the rest. That is deliberate: a skipped number in the middle of a bundle is more noticeable. And double-sided printing depends on your printer: this tool lays out the pages, it does not drive the driver.

Nothing is uploaded. Cut your network connection once this page has loaded: the tool keeps working. How to check it yourself.

• Organize pages : Reorder, rotate, delete, duplicate: the whole plan.
• Extract pages : Pick pages, take them out into a document of their own.
• Delete pages : Remove pages while looking at them, and they do not survive under the file you get.
