History and versioning

The History feature lets you label and manage different versions of your project. You can view, download and compare project versions, restore previously deleted files, and see content added by collaborators at a glance.

Using the full History feature

The project owner needs to be on a premium subscription in order for them and their collaborators to access the full history.

How to access a project’s history

Click on History, located above the preview panel, to access the History feature. You can then select:

How to return to editing mode

To exit the History mode and return to normal editing mode, just click on History again.

What happens to the history if you copy a project?

A copied project starts with a completely new, fresh history—the original project’s history is not copied to the new project.
