Removed the wrong page? Undo brings it back
· Using ToPDF
The × on a thumbnail is convenient — which also makes it mis-tappable. Rather than a nagging “are you sure?” on every removal, ToPDF removes immediately and offers a short window to change your mind.
How Undo works
- Tap × on a page thumbnail — the page disappears and a toast slides up: “Page 3 removed — Undo”.
- Tap Undo within a few seconds. The page returns to its exact position, keeping its crop, rotation and place in the order.
- Ignore the toast and it fades; the removal stands.
What Undo protects (and what it doesn’t)
Undo covers page removal — the destructive mis-tap. Rotation isn't destructive (tap Rotate three more times to get back), re-cropping isn't destructive (the original photo is kept), and reordering is trivially reversible by dragging back. The one action that discards a whole document — New scan — asks for confirmation instead when multiple pages would be lost.
Frequently asked questions
How long do I have to undo?
About six seconds — enough to react to a slip without leaving a lingering “deleted items” state on a privacy-focused tool.
Can I undo two removals?
The toast covers the most recent removal. If you removed two pages by mistake, undo the last one, then re-add the other from its photo.
