Frequently Asked Questions
Can I undo a drag-and-drop reorder? ▼
Drag the page back to where it was, or refresh the page and re-upload to start fresh.
Is there a page limit? ▼
No hard limit — very large PDFs with many pages may be slower to render thumbnails for.
Will the quality of the PDF change? ▼
No — rearranging doesn't alter content or quality, only the page order.
How Reordering Works Under the Hood
pdf-lib's copyPages() method extracts page objects from the source PDF in your chosen sequence and adds them to a new document in that order. The visual drag-and-drop interface maps to a page-index array that gets passed to this method — so what you see in the thumbnail grid is exactly the page order in the output PDF. No content is re-rendered or re-compressed; quality is preserved perfectly.
Common workflows: fixing a scanned document where pages were fed in the wrong order, moving an appendix to a different position, bringing a summary page to the front for an executive audience. After reordering, use Add Page Numbers to renumber pages in the new sequence — this is important after significant reordering to maintain document navigation integrity.
