How it works
One list of pages
Every PDF you add is read in your browser and its pages join one list, in the order the files arrived. The list is the document you will download: drag a page to move it, or pick pages and use the toolbar to rotate, duplicate, move or remove them.
Shift, Ctrl or Cmd adds a page to the pick, so several pages can turn or move together. Delete or Backspace removes the focused page.
Merging
Merge copies each page, with its text, fonts and images, into a new PDF in the list's order. Rotation is added to the page's own rotation in quarter turns, so nothing is redrawn and text stays selectable.
Splitting
By ranges makes one file per comma-separated part, counted in the current order: “1-3, 4, 5-8” gives three files. Every page makes one file per page. Several parts download together as a ZIP.
1-3, 4, 5-8 → part-1 (pages 1–3), part-2 (page 4), part-3 (pages 5–8)
