Can I delete pages while reordering?

Yes. Each thumbnail has a remove button (×). Pages you remove are excluded from the downloaded PDF. You can also restore the original order at any time using the Reset button.

Does reordering preserve form fields and bookmarks?

pdf-lib copies each page as a self-contained unit, preserving embedded text, images, and vector graphics. Complex interactive elements such as form fields and named bookmark destinations may not survive a page reorder because they rely on cross-page references. For signed or heavily interactive PDFs, test the output before distributing.

Can I move multiple pages at once?

Yes. Hold Shift and click to select a range of pages, then drag the selection to its new position. All selected pages move together as a group.

Is there a page limit?

There is no hard page limit. Thumbnail rendering is done locally page-by-page, so a 200-page PDF will take longer to load than a 10-page one. The practical limit depends on your device's available memory — most modern laptops handle 500+ pages without issue.

Does the file leave my browser?

No. The entire process — thumbnail rendering via PDF.js and PDF assembly via pdf-lib — runs in your browser. Your file is never sent to any server.
