Is my file uploaded to a server?

No. This tool runs entirely in your browser via WebAssembly — your file never leaves your device. You can verify this in your browser's DevTools Network tab.

What can I do to pages here?

Drag to reorder, and select pages to rotate, duplicate, or delete. Multi-select with Ctrl/Cmd-click or Shift-click for a range.

Is the original PDF modified?

No — you build a new arrangement and download it. The source file is never changed, and nothing is uploaded.
