    How to use this tool

    1. Drag and drop your PDF into the box above, or click to browse and select it.

    4. Press Apply & download to build and save a PDF with the new page order (use Reset order first if you want to start over).

    FAQ

    Frequently asked questions

    Is my PDF uploaded anywhere?

    No. Pages are previewed and reordered entirely inside your browser using pdf.js and pdf-lib — your file never leaves your device.

    How do I change the page order?

    Drag any page thumbnail and drop it where you want it — the grid reorders live as you drag. On touch devices, use the up/down arrow buttons on each thumbnail instead.

    Does reordering affect page content or quality?

    No. Pages are copied exactly as-is, only their order changes.

    Can I undo a reorder?

    Use the "Reset order" button to restore the original page order at any time before downloading.
