Normalization steps
Manage Pages
Reorder pages by dragging cards, remove pages, insert pages from another PDF, or add split points for multi-document export.
Current Arrangement
Drag cards to reorder. Check “Start new document here” on any page after the first to split the PDF at that point.
Drop here to move a page to the end
Insert Pages
Upload another PDF, pick the pages to insert, and choose where they should land in the current arrangement.
No insert PDF loaded.
Split & Apply
Applying updates the active PDF in the workspace and preserves field overlays on kept pages. Split download exports the current arrangement as multiple PDFs.
Split downloads use the current PDF pages. If you have unsaved field edits, apply the arrangement to the workspace first and export afterward to embed those fields.
