Saving, exporting and sharing boards

Autosave

A board saves by itself a moment after every change. The top bar shows Unsaved changes, Saving and then Saved.
Press Ctrl + S to save straight away.
If the connection drops, the top bar shows Offline, retrying, and the board saves as soon as it is back. Keep the tab open until it says Saved.
Undo and redo (Ctrl + Z and Ctrl + Y) work for everything you did since you opened the board.

Two people can open the same board. Each save checks that nobody else saved in between, so no work is overwritten without you knowing.
If someone did, a banner says who changed it and offers two buttons.
Reload theirs opens their version. Your changes since your last save are dropped.
Keep mine saves your version over theirs. Their changes since then are replaced.
To keep both, export yours first (Download the board file), click Reload theirs, then open your file from the board menu: it is added beside theirs.

Click Export in the top bar, or open the board menu at the top left.
PNG image: a picture of the whole board, for slides, emails and documents.
SVG image: a sharp image that stays crisp at any size, for design tools and websites.
Board file (.json): everything on the board, including images, to keep as a backup or to add to another board.
To add a board file to a board, open the board menu and click Open a board file. What it holds is added beside your drawing, never over it.
To copy part of a board as an image, select it and press Shift + Alt + C, then paste it anywhere.

Click Share in the top bar.
Click Create link.
Click Copy and send the link to anyone, for example a client or a colleague in another workspace.

The board full screen with a View only badge. They can move around, zoom and export it as an image, but cannot change anything.
They do not need an account and do not see your workspace, your other boards or who made it.
They always see the latest saved version.
Search engines are told not to list shared boards.

Click Share, then Turn sharing off. The link stops working at once for everyone.
Sharing again makes a new link. The old one never works again.
Shared boards show Shared on the Board page.
