Xara Cloud can be used to edit and republish .xar documents. There are many Desktop customers allowing their clients to use Xara Cloud for website updates in particular. Others use Xara Cloud in the new document/design collaboration process with commenting and online review sessions. It is really powerful when the client sees the designer making changes in real-time on the screen. However, nothing is perfect and we are thankful for the customers reporting compatibilities issues. Obviously, it is impossible for us to support all old .xar files in Xara Cloud but we try as much as it makes sense. All you need to do is share edit the .xar file from within Xara Cloud. Coming in a few weeks will be multiple company support so you can set up a sandbox for each of your clients. More details coming...

You have pointed out features that Xara Cloud does not have, nor does it claim to have, and nor do they impact the ability for a client to do simple edits and republish with Cloud. To date, these capabilities have not been requested by Cloud users but we do appreciate that they might be important to you.

Hopefully, all Xara Cloud templates work in the Desktop products. Save the file in your cloud storage of choice is it is accessible by both products. Easy. Leveraging cloud storage for documents is seamless for users that take advantage of the benefits of Xara offline/online editing of which it was designed for.

Happy creating!
