How it works
Drop the PDF
Every page is rendered as a thumbnail in the workspace. Add a second file and its pages join the grid, labelled with the file they came from.
Arrange
Drag a page to a new spot, or select several with click and shift-click and drag them together. Rotate, duplicate and delete work on the selection or on a single page.
Insert
Add a blank page after the selection, or pull pages from another PDF into the exact position you want.
Save
A new PDF is written from the pages you kept. Each page carries its own rotation, so nothing is re-rendered and quality is untouched.
Pages are copied, never re-rendered, so text stays sharp and searchable.
Pages from any number of PDFs can be mixed into one.
Every change can be walked back before you save.
What the tool actually changes
A PDF stores its pages as a tree of page objects, and the order you see in a reader is simply the order of that tree. Reordering pages means rebuilding the tree in a new order and pointing each entry at the same page content as before. Nothing inside the page is touched: fonts, images and vector drawings are carried across byte for byte.
Rotation is a single number on each page, so rotating a page here writes that number and leaves the content alone. Deleting a page drops it from the new tree. Because the output is a fresh document, anything that depended on the old page order is left out: bookmarks that pointed at pages, and links between pages. If your file relies on those, add the bookmarks again afterwards with the merge tool, which can write a bookmark per file.
Fixing a duplex scan
A one-sided scanner asked to do both sides of a stack produces the fronts in order and then the backs in reverse: 1, 3, 5, 6, 4, 2. The Fix duplex scan order button interleaves the two halves so the pages read 1 to 6. It assumes the second half is reversed, which is what a stack flipped over produces; if your scanner reverses nothing, use Reverse order on the second half instead.
Selecting many pages
Click a page to select it and shift-click to select a run. The odd and even buttons select alternate pages, which is the fastest way to delete every blank back side of a single-sided document that was scanned as duplex. When you drag a selected page, every selected page moves with it and keeps its relative order. The thumbnail size slider makes a 200 page scan manageable or a 6 page contract readable.
Privacy
The whole tool runs in your browser. The files you drop are read into memory on your device, the thumbnails are drawn on your device, and the new PDF is assembled there too. Nothing is uploaded, and closing the tab discards everything.

Common questions
What people ask before they press the button.
01Does reordering pages lose quality?
No. Pages are copied as they are, including their fonts and images. The output is not a re-rendered copy, so text remains selectable and searchable.
02Can I combine pages from two PDFs?
Yes. Drop several files at once, or use Insert from another PDF to place a file's pages after the page you have selected. Each thumbnail is labelled with the file it came from.
03What happens to bookmarks and links?
They are not carried into the new file, because they pointed at positions in the old page order. Form fields and annotations on each page are kept.
04How do I add a blank page?
Select the page the blank should follow and press Insert blank page. The blank takes the size of that page. With nothing selected it goes at the end.
05Is there a page limit?
No fixed limit. Thumbnails render progressively, so a large file is usable while the later pages are still drawing.
06Are my files uploaded?
No. Everything runs in the browser on your device.
