Reorder PDF Pages — Free, Nothing Uploaded

What page order is, inside the file

A PDF is a pile of numbered objects plus a table saying where each one starts. One of those objects is the page tree, and it holds a /Kids array that lists every page. That array is the order. Page 7 is the seventh entry in it — no page records its own number, which is why the number printed on a page can disagree with its position in the file, and often does in a scanned document.

So reordering moves nothing. The tool reads your file and writes a new one, listing the pages in the order you asked for. Each page is copied with everything it points at: its content stream, its fonts, its images, its annotations, all renumbered to fit the new file. The drawing instructions are copied as bytes and never decoded, which is what makes this lossless — no image is re-compressed, no text is re-encoded, and a page that has been through this tool ten times looks exactly like the one that went in.

Why a page can be in the list twice

Because two entries in that array are allowed to point at the same content. Name a page twice and you get two page objects sharing one content stream, so a 3 MB page repeated ten times does not produce a 30 MB file — it adds a few hundred bytes. It is a legitimate thing to want: ten copies of a form, a separator sheet between sections, one card printed eight-up. Most tools refuse it on the assumption that you made a typo.

How the order box reads

Page numbers and ranges, separated by commas, and the file comes out in exactly that sequence:

• 1, 3, 2 swaps two pages and leaves the rest where a range puts them.
• 4-8 is pages four through eight in order; 8-4 is the same five pages reversed.
• 2, 2, 2 is one page, three times.
• A page you never name is simply not in the new file. The tool lists those pages before you build anything, because leaving one out by accident is the easiest mistake to make here. If dropping pages is the actual job rather than a side effect, taking them out by number is the tool built for that.

The box and the arrows are the same thing seen twice. Move a row and the text rewrites itself; type a new order and the rows rearrange. Nothing is applied to your original file, which is still sitting on disk untouched — this writes a new one.

Why each row says 612 × 792 pt

A point is 1/72 of an inch, the unit PDF measures everything in. 612 × 792 is US Letter, 595 × 842 is A4. When a row shows portrait numbers and a rotation badge of 90°, the page was drawn portrait and carries a note telling the reader to turn it — rotation in a PDF is metadata, not pixels, which is why turning a page is instant and costs nothing. A page has no resolution of its own, so these numbers say nothing about print quality.

Where this falls short

• There are no page previews. Rows say "Page 4", not what page 4 looks like. Drawing a page means a font engine and a rasteriser, which is megabytes of code, so this tool identifies pages by number and size only. Open the file alongside in your PDF reader and work from its page numbers.
• Bookmarks are dropped. The outline in the sidebar lives in the document catalog, pointing at pages in the old order. The new file is written with a fresh catalog, so it comes out without one.
• Links that jump inside the document stop working. The link is copied, but the page it names is not the page that ends up in the new file, so clicking it does nothing useful. Links to a web address are unaffected.
• A page you leave out is off the page list, but its bytes may still be in the file. If the document has internal links, some of the material they point at is carried along. Do not use this to strip a confidential page — for that, delete the page in an app that rewrites the whole document, and check the result.
• A one-page PDF is turned away. A single page has no order to change, so the tool says that instead of handing you a list with one row in it. If what you wanted was several copies of a one-page file, joining files accepts the same file more than once.
• Password-protected files are refused, not cracked. Remove the password in the app that made the file first.
• Form fields come across drawn but inert. The widgets are copied, the form machinery that makes them fillable is not, so a filled-in form keeps its appearance and loses its fields.

What does survive is the part most people are asking about: the pages themselves, at full quality, with their sizes, their rotations, their images, their selectable text and their comments, plus the document title and author. A file whose index is damaged is rebuilt by scanning for page objects, and the tool says so when that happens, because a rebuilt index sometimes finds pages in a different order than the one you saw.
