Undo, redo and autosave

Your changes are saved automatically. Use Undo and Redo to step back and forward.

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

How autosave works

Every change is saved immediately. The title bar does not show an unsaved-changes indicator because there is nothing to save manually.

Undo and redo

Click the Undo and Redo buttons in the editor toolbar, or press Ctrl Z / Ctrl Y.

What cannot be undone

• Deleting a file from the file manager (not an editor action).
• Exporting or sharing a file (the export itself is not reversible, but the original file is unchanged).

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.
