As a user I could like to download as an image
I'd like to download Visio drawings in image format
Thank you for valuable feedback. I’m glad to inform that we have now enabled the functionality to download files as JPEG/PNG images in Visio for the web for the end users. You can choose from the various customization options available in the export dialog.
