Enter a comma-separated list of page numbers and the tool builds a new PDF whose pages follow exactly that order. Pages you leave out are dropped and pages you repeat are duplicated.

About this tool
Updated
You describe the new order as a list
Type the page numbers in the order you want them, separated by commas, and a new PDF is built to match.
Entering 3,1,2 produces a document whose first page is the original page three, followed by pages one and two. The numbers refer to positions in the original file throughout, so you never have to track how earlier moves shifted things. That makes a complicated rearrangement easier to reason about than dragging pages one at a time, as long as you write the list carefully.
Pages you leave out do not come along
Only the pages you list appear in the result, so omitting a number removes that page.
This is the behaviour that surprises people, and it is also useful once you know. Listing 1,2,4,5 on a five-page document gives you a four-page file with page three gone. If you mean to keep everything, make sure every page number appears exactly once, and count the result before relying on it. When removing pages is actually the goal, Delete PDF Pages is more direct and less error-prone.
Repeating and reversing
A number can appear more than once, which duplicates that page, and a descending list reverses the document.
Writing 1,1,2 gives you two copies of the first page. Writing 5,4,3,2,1 flips a five-page document end to end, which is the quick fix for a stack scanned back to front. Both fall naturally out of the same list format rather than needing separate tools.
The pages themselves are untouched
Each page is copied into the new document as it is, so text stays selectable and nothing is re-compressed.
Quality is identical because nothing is rendered or rebuilt. What does not survive is anything tied to the document as a whole: bookmarks and the outline point at the old page order and are not rewritten, so check them if your document relies on them. Links between pages can break for the same reason.

FAQ
Do I have to list every page?
Yes, if you want to keep them all. The result contains only the pages you type. If a 10-page file and you enter 2,1, you get a 2-page PDF. This is handy for reordering and trimming in one go, but easy to do by accident, so check the page count of the result.
Can I type ranges like 1-5?
No. Only single numbers separated by commas are understood. Type 1,2,3,4,5 instead. An entry like 1-5 is read as the number 1 only.
What if I make a typo, such as a page number that does not exist?
Numbers larger than the page count, zero, negatives and non-numeric entries are skipped without an error message. The result will simply have fewer pages than you typed, so compare the page count against your list.
Will bookmarks, links and form fields survive?
Do not count on it. The pages are copied into a fresh document, so document-level items like bookmarks and outlines are not carried over, and links or form fields that point elsewhere in the file may stop working. Page content itself, including images and text, is preserved and is not re-rendered.
Is my PDF uploaded?
No. The pages are reordered in your browser and the new file is created there.
