PDF Page Reorder
See every page as a thumbnail, drag them into the order you want, and export a rebuilt PDF. Runs entirely client-side.
About PDF Page Reorder
Scanned documents come out of feeders in the wrong order surprisingly often, and merged reports frequently need a section moved. This tool renders every page as a thumbnail so you can see what you are moving, then rebuilds the PDF in whatever order you arrange.
Drag a page to move it, or use the arrow buttons if you prefer keyboard and click control. A reverse action is included because reversing an entire document is the single most common fix after a double-sided scan runs backwards.
Thumbnails are rendered locally with PDF.js and the output is assembled with pdf-lib. Both run in your browser, so a confidential document can be reorganised without uploading it anywhere.

- 1Upload a PDF — every page appears as a numbered thumbnail.

- Putting a cover page first after combining several files
Frequently asked questions
Does reordering reduce the quality of the pages?
No. Pages are copied between documents intact, so text stays selectable and images keep their original resolution. Nothing is rasterised or re-encoded — only the page order in the document structure changes.
Can I delete pages here too?
This tool focuses on order. To remove pages, use the Remove PDF Pages tool, which takes page numbers or ranges directly.
Why are the thumbnails slow on a large PDF?
Each thumbnail is a real page render happening on your device. A document with hundreds of pages takes a moment on first load, especially on a phone. The reordering itself stays instant once thumbnails are ready.
Are bookmarks and links preserved?
Page content, text and images are preserved exactly. Document-level features such as outlines, bookmarks and internal link targets are not carried across, because the output is rebuilt as a fresh document.
