Yes, you can use Microsoft Paint online:

• All devices, operating systems, and major browsers such as Chrome, Firefox, Opera, and Internet Explorer are compatible with the web-based application.
• In previous versions of MS Paint, the user had only three chances to undo or redo his actions. You have infinite redos and undos in MS Paint online.
• Your work will be autosaved if you allow storage on your local system.
• Stretch/Skew allows you to stretch an image by more than 500% in a single attempt.
• Assume you and a group of friends are intending to collaborate on a project. You can create a new multi-user session and invite your friends to join. 
• This, however, is not a straightforward process. Your buddies' actions may cause you to lose focus on your current task. Furthermore, these meetings are not private, and you risk losing your work at any time.
• Because SVG is supported by most browsers, you can use this app to open and edit SVG files.
• Using Ctrl + and Ctrl + >, you can easily rotate the photos. What's more, instead of rotating photographs via 90 degrees, you can rotate them through any angle you like.
