Feature Request: Set or remember a default zoom level

[Cthu1hu-zoo]

I would like to be able to return to a document at the same zoom level as when I left it. RIght now, with an infinite canvas, it appears to default to 100%

👋 Thank you for opening this issue!

Summary: The user requests that draw.io remember the zoom level (and implicitly the viewport position) when reopening a diagram, rather than resetting to the default 100% zoom on an infinite canvas. This is closely related to the previously filed (and stale-closed) issue #2861 which requested the same capability.

This issue might be related to existing issues:

🔴 #2861 - Open diagram where last worked on
Issue #2861 requests the same core behavior — remembering the last viewport location and zoom level when reopening a diagram. The current request for remembering default zoom level is essentially a subset of that broader request to restore the last editing state.

Please check if any of these address your issue. If this is a duplicate, we may close this issue and continue the conversation there.

📝 Additional Information Needed

To help us investigate this more effectively, could you please provide:

• platform: Which platform is being used — draw.io Desktop, web (app.diagrams.net), VS Code extension, Confluence/Jira integration, etc.?
• file format/storage: How are the diagrams stored — locally, Google Drive, OneDrive, etc.? This may affect whether state can be persisted.

We also have some questions:

• Are you using draw.io Desktop, the web version (app.diagrams.net), or an integration (e.g., VS Code, Confluence)?
• Would you prefer the zoom level and viewport position to be saved per-file (embedded in the .drawio file), or as a global default preference?

In answer to the questions - I checked the issue you referred to, it does not look like it was ever actually resolved or implemented, so I think my request is still valid. I am using draw.io desktop on a Windows 11 laptop, and local files. I would like the zoom level and viewport location to be saved per-file by preference, but a global setting would be an acceptable alternative.

The problem with this is draw.io is a multi-user app. We don't know whose zoom level and positioning we're saving to a file.

You could have a case in collaborative editing where many users are constantly saving their zoom and positioning. The chances would be that you'd re-open and file with someone else's settings, that would be even more off-putting than the current system.

Fair, I guess I'm only seeing it from my own use-case, which is as a single user.

It should default to 100% or less depending on your diagram. Which version are you using?
