Organize PDF Pages

Every page loads as a thumbnail in a grid. Use the ‹ (move left) and › (move right) buttons under a thumbnail to shift it earlier or later in the document — the thumbnail's position in the grid is exactly the order it will appear in the rebuilt PDF. Nothing is written until you click Build PDF.

Click the ⟳ button under a thumbnail to rotate that page 90 degrees clockwise; click it again to keep rotating in 90-degree steps (90, 180, 270, back to 0). The thumbnail rotates in place so you can see the result, and only that page is affected. The rotation is stored as the page orientation flag, so the content is not re-rendered.

Clicking ✕ marks a page for removal — its thumbnail dims to show it is excluded, and the button toggles again to bring it back if you change your mind. Deleted pages are simply left out when the new PDF is built; nothing is deleted until you click Build PDF. The file on your device is never modified; you download a new one.

One single PDF. Clicking Build PDF copies every page that is not marked deleted, in its current grid order and with its current rotation, into one new document — this tool is for rearranging a single file, not splitting it into pieces. Use Split PDF when you want one file per page.

Build PDF refuses and shows a message asking you to keep at least one page. A PDF needs at least one page, so you cannot rebuild an empty document. Toggle any page back on and build again.

No — the PDF stays on your device. Thumbnails are rendered locally with the same engine Firefox uses to display PDFs, and the rebuilt PDF is assembled entirely in your browser with a client-side PDF library. Nothing is uploaded, logged or stored — closing the tab clears everything.
