PHP - Linking to html files is wrong in Pdf-to-html - php

Question

I have installed Poppler Utils for windows in addition to https://github.com/mgufrone/pdf-to-html
It works perfectly and it converts PDF files to HTML, by making a single HTML file contains 2 iframes, one for pages navigation and the other for the actual text.
The problem is when the HTML files are generated, the linking for iframe src gives a false linking.
For Example:
Test.html
Pages.html
Page_1.html
All these files exist in the same folder named "Output".
Test.html contains 2 iframes linking to Pages.html and Page_1.html
Here's the problem in Test.html:
<frameset cols="100,*">
<frame name="links" src="output/Pages.html"/>
<frame name="contents" src="output/Pages_1.html"/>
</frameset>
Should be:
<frameset cols="100,*">
<frame name="links" src="Pages.html"/>
<frame name="contents" src="Pages_1.html"/>
</frameset>
