Reorder PDF Pages

What this tool does

This is a free tool to reorder PDF pages — it rebuilds a PDF with its pages in whatever sequence you choose, without uploading anything. You open a PDF, select and move visual page thumbnails into the order you want (or just type the new order), and download a fresh copy with the pages rearranged. It solves the very ordinary annoyance of a PDF whose pages are simply in the wrong order: a scan that came out back-to-front, a cover sheet stuck at the end, or two chapters that ended up swapped.

The reorder runs entirely in your browser, which is exactly what you want when the document is private — a report, a scan, or paperwork you would never want to upload to a third-party site.

How to use it

1. Open your PDF. Drag it onto the drop zone, or tap Choose file to pick it. The tool reads it on the spot and renders a private thumbnail for every page.
2. Set the new order. Drag a page card, use its up/down buttons, or select several pages and move the group before a chosen position. On a phone you can also type the order into the New order box — for example 3, 1, 2 to put the third page first.
3. Save the reordered PDF. Press Save reordered PDF; the new file is built in your browser and downloaded straight to your device. No account, no queue — get your file and go.

How it works (the method behind it)

The tool reads your PDF from your device into memory and parses it with pdf-lib, an open-source JavaScript PDF library. It then creates a new, empty PDF and copies your pages into it one at a time, following the exact order you set, using pdf-lib's copyPages operation. Because each page is copied as a whole object, its text, fonts, and images are preserved — nothing is re-rendered, flattened, or compressed, so quality is identical and text stays selectable. When the last page has been copied, the new document is serialized to bytes and handed to you as a download. Every step happens in your browser tab, so your file never travels across the network.

Examples

• A 3-page scan that came out reversed. The pages arrived as 3, 2, 1. Type 3, 2, 1 (or drag them) and download a correctly ordered copy.
• Cover page stuck at the end. A 10-page report has its title page as page 10. Type 10, 1-9 to move it to the front in one step.
• Two swapped sections. A document where pages 4 and 5 belong before page 3: type 1, 2, 4, 5, 3, 6 to slot them into place.

Common use cases

• Fixing the order of a multi-page scan that fed through the scanner back-to-front.
• Moving a cover sheet, title page, or appendix to where it belongs.
• Re-sequencing chapters, sections, or slides before sending a document on.
• Putting signed or initialled pages back into their correct position in a contract.
• Anyone who needs to rearrange a PDF but refuses to upload a private document to a website.

Why use this one

• Your document never leaves your device. The reorder is done locally — check your browser's Network tab to confirm there is no upload. SmallPDF, iLovePDF, and Adobe all upload your file; this tool does not.
• See the pages you are moving. Private in-browser thumbnails replace guesswork from a number-only list, while original page numbers remain visible.
• Move one page or a whole group. Select scattered pages or Shift-select a range and move them together. Drag, arrow buttons, and the typed-order fallback remain available on phones and desktops.
• Free and unlimited. No "2 free tasks per hour" wall, no file-size cap, no signup, and no watermark on the result.
• No quality loss. Pages are copied whole, so text stays selectable and images keep their resolution.

Tips and limits

• The order shown on the visual board is the order in the final PDF, so arrange the cards (or type the order) before you save.
• You can drop a page by leaving its number out of the typed order, or duplicate a page by typing its number twice — handy for quick fixes.
• Reordering a very large PDF uses significant memory; this works best on a desktop, and on a phone you should stick to reasonably sized files.
• Need to combine separate PDFs instead? Use Merge PDF. Want to throw pages away rather than move them? Use Delete PDF Pages. See all the PDF tools.
