I have a Corel Draw .cdr file which has a full design of a web page. Is there any way to convert that design into HTML template?
You can load the .CDR into CorelDraw and export it to HTML.
Since .CDR is a proprietary file format, CorelDraw is the best at opening them without 'weirdness'.
But if you don't have CorelDraw then (according to Wikipedia) the CDR file format import is partially or fully supported in following applications:
In CorelDraw X7 you will go to File > Export For > HTML
Otherwise HTML is not an option in the regular export menu.
