html2canvas script appears unused.
The html2canvas library is loaded but doesn't appear to be used anywhere in the main.js script. This adds unnecessary overhead to the page.
Consider removing the unused html2canvas script to improve performance:

Length of output: 43
I’d like to broaden the search to include HTML as well as JS/TS files. Let’s rerun with a more comprehensive pattern:
This will help confirm whether the library is ever invoked. If this still yields no hits, we can conclude it’s unused.
🏁 Script executed:
Length of output: 185
Remove unused html2canvas import
It looks like
html2canvasis only ever loaded inPROJECTS/ImgToPDFly/index.html(line 161) and never actually invoked in your HTML, JS or TS files. You can safely drop it to reduce page weight:• PROJECTS/ImgToPDFly/index.html: line 161
