Hi @jayashri p thank you for posting in the community! Lucidchart supports imports from Visio Gliffy Draw.io and OmniGraffle however importing an editable .pdf .jpeg or .doc file is unfortunately not currently support. 

We're always looking for ways to improve Lucidchart and your feedback is the best way for us to do that. Would you mind adding your idea to our feature request form? Ideas submitted to this form are passed on to the product development team for their consideration.

Thanks for your request and I apologize for any inconvenience this causes you.
