Hello, @bharatnxtin. Thanks for reaching out.
Please accept my apologies for the late reply
You are correct. The output PDF file contains the screenshot (canvas) of the element you’ve indicated in the plugin action. This is expected behavior.
Unfortunately, the latest plugin versions have a bit lower PDF page quality. In this case, I can recommend you using the 1.27 plugin version. It has way much better quality, but also it includes some bugs that were fixed in later versions. (not crucial bugs)
Please also note that the way you have to set up the ConverttoPDF plugin action on the 1.27 version differs from the setup methods on the latest versions. You should also use the Legacy plugin element if you want to use the plugin on the 1.27 version.
Please let me know if there is anything I can help you with.
