Pages end up in the wrong order for mundane reasons. A duplex scanner produces all the fronts and then all the backs. Someone scanned the stack upside down. A report was assembled from three sources and the sections landed out of sequence. Fixing it by printing and re-scanning is absurd; fixing it here takes a few drags.
Every page in the document is shown as a thumbnail. Drag them into whatever order you want, rotate any that need it, delete any that do not belong, and save. The pages themselves are copied with pdf-lib rather than re-rendered, so the document you get back is the same document with its pages in a different sequence — not a degraded copy.
The whole rearrangement happens in your browser. Nothing is uploaded, which also means a hundred-page scan reorders as fast as your machine can draw the thumbnails.
-organized suffix.The most common reordering job is a two-sided document scanned in two passes: pages 1, 3, 5, 7 in the first run and then 8, 6, 4, 2 or 2, 4, 6, 8 in the second. Merge the two scans into one document first, then drag the back pages into position between the fronts.
If the back pages came out upside down — which happens when the stack is flipped the short way — select them all and rotate 180 degrees before you start reordering. Doing the rotation first means you can see what you are dragging.
No. Pages are copied as complete PDF objects into a new file in your chosen order. Text stays selectable, fonts stay embedded and vector graphics stay sharp.
Yes. The same grid supports dragging, rotating, selecting and deleting, so everything can be fixed before you save once.
Pages are dragged individually. For a large rearrangement it is often faster to delete a block of pages, then add the correctly ordered file back in with Add PDF Pages.
They are not carried over. Page content copies faithfully, but document-level structures such as the outline and form fields are not transferred.
Yes. Add several files and all their pages appear in the same grid, so you can interleave them freely before saving as one document.
No. Thumbnails are rendered by PDF.js and the new document is written by pdf-lib, both inside your browser.
