Change the exported PDF file version

Hello All!
I’m new to Invoiceplane (1.6.3) and was wondering if it was possible to change the PDF file version that is exported. If I click get info on a PDF, it says the PDF version is 1.4. I was wondering if it is possible to change the default exported PDF to version 1.7? If it is possible, which file must I edit? I would think there is a config file somewhere with this, but I was unable to locate one. Thank you for your time!

Hi there,

No idea if it is possible.
check PDF Version – Setting PDF file properties – mPDF Manual

and to set those variables i would try to do it in this file: InvoicePlane/application/helpers/mpdf_helper.php at development · InvoicePlane/InvoicePlane · GitHub
