How does PDF preview work?

pdf.js thumbnails each page locally. Without the vendor bundle, processing may still run but thumbnails show guidance text.

When does drag reorder apply?

Extract mode creates a PDF in dragged thumbnail order.

Delete mode removes selected pages while preserving remaining page order.

Remove pages after preview and download a cleaned PDF locally.

One PDF renders thumbnails. Tap to select pages; in extract mode you can drag to reorder.
