Our designers currently save out HTML5 files to PDFs to upload as proofs. To skip that step, is there a way to create proofs directly from the HTML5 files? Would they need to be housed on a staging site first? Thanks!
as HTML5 is a web standard, but not a filetype, this is a bit difficult to answer.
On that basis, something like this is not suitable as a classical proof in the sense of Workfront.
So, I assume that, in the moment your designers save to PDF the whole result is rendered first and saved as PDF.
I hope this helps.
