Page management

Reorder, rotate, merge, split, duplicate, delete — all from the thumbnail rail.

Organize pages

• Reorder: drag thumbnails into the order you want.
• Per-page controls: each thumbnail offers rotate, duplicate, delete, and insert-blank.
• Rotate: turn any page 90°, 180°, or 270° clockwise.
• Merge: merge another PDF at any position — or just drop a file onto the canvas.
• Delete / duplicate / insert blank: one click per thumbnail.

Sideways scans get a one-click, undoable "Turn upright" banner — for 90°, 180°, and 270° camera-rotation metadata alike. Mirrored artwork (a generator bug that shows in every viewer) is fixed with per-page horizontal/vertical flip: the export mirrors the real content while your marks stay put.

Extract and split at export

In the Save dialog:

• Extract a range — e.g. 1-3,5 — to export only those pages.
• Split — emit one file per page.

Compare two versions

Press Compare, drop in two files, and read the diff — additions in green, removals in red, with per-page counts. Built for "did the contract terms change between versions?"

Automate it

pdfstudio merge a.pdf b.pdf -o combined.pdf
pdfstudio split in.pdf --ranges 1-3 --ranges 4-6 -o "part-%d.pdf"
pdfstudio rotate in.pdf --angle 90 -p 1-2 -o rotated.pdf
pdfstudio pages in.pdf --delete 5 --order 3,1,2 -o reordered.pdf
