A fun trick I do with my web based drawing tools is to save a JSON representation of your document as a comment field inside of a PNG. This way the doc you save is immediately usable as an image but can also be loaded back into the editor. Also means your downloads folder isn’t littered with unintelligible JSON files.

This would be great for things like exported Mermaid diagrams.
