Kiwi PDF saves your work automatically while you edit — you never need to tap a Save button.

How autosave works

Every annotation, text edit or page change is saved to the file within half a second. Changes are also embedded as standard PDF annotations so other apps can read them.

Undo and redo

Tap the ← (undo) and → (redo) arrows at the top left of the editor.

A single tap undoes the most recent action. You can keep tapping to step back through your whole session.

Moving, resizing or rotating an annotation with a single drag counts as one undo step — you won't have to tap undo dozens of times just because you repositioned something carefully.

What cannot be undone

Undo history is cleared when you close the editor. Reopening a file starts a fresh history.

Only saves when you make a change

Kiwi PDF only writes the file when you actually edit it. Simply opening and viewing a PDF — even selecting annotations — does not trigger a save. This protects the file's modification date and any digital signatures.
