Page 12 is your appendix, but somehow it ended up as page 12 of 80. You need it at the actual end. The signature page is page 30 but should be page 80.
Moving to the end is one drag. Flint supports it directly.
Drag to the end
Open reorder PDF. Find the page that needs to be last. Drag its thumbnail to the bottom of the grid — past the last page. Drop. The page now sits at position N (where N is the total page count). Save the file.
Move by page number
If thumbnail-dragging is awkward for a giant document, use the page-number input. Type '12 to end' (or similar syntax) and Flint executes the move. Faster for documents where scrolling to find the page would take longer than typing.
Multiple pages to the end
Select several pages, drag them to the bottom together. Their relative order is preserved. Or specify a range: 'pages 12, 30, and 45 to end'. They end up at positions N-2, N-1, and N respectively.
Don't forget bookmarks
If a bookmark points at the moved page, it follows. So 'Appendix A' still links to the appendix wherever it ends up. This is the difference between a real reorder (Flint) and a 'visual rearrange' that breaks navigation.
FAQ
Can I move a range to the end?
Yes. Select the range, drag to the bottom. Or use range input.
What if 'last' is ambiguous (e.g. multiple pages should go last)?
Order them within the selection, then drag the whole selection to the end. Relative order in the selection becomes their final order.
Does this affect page numbering?
The original page labels stay with the pages. Page 12 (original label) is now physically at position N.
Can I add a blank page at the very end?
Use edit PDF to insert a blank page, then reorder if needed.
Drag to the bottom, save. Move to the end.
