I stumbled upon a solution. There is a google chrome extension which captures elements of a webpage, effectively enabling the user to capture a single submission as image file. it is called ‘HTML Elements Screenshot’
works for all chromium based browsers like Microsoft edge, Google Chrome etc.
Hope this helps.
Pros: it is free tool
Cons: image data of the submission is not captured. Atleast, i couldn’t figure out a way to do it.
Another option is the extension called ‘Fireshot’
The pro (paid) version of ‘Fireshot’ extension overcomes the shortcomings of ‘HTML Elements Screenshot’ i.e. even image data in the submission is also captured as pdf or image file.
The difference in output of both extensions can be seen as below.
