Does Workfront support amphtml files, or are there any workarounds?


Level 6

Designer is not able to upload and preview this (newer?) file type:

AMPHTML Formats: ZIP containing 1 HTML doc and up to 39 media assets

Max Size: 150 KB

We’re looking into using a new ad format for digital banner ads called AMPHTML.

They’re animated but basically consist of an html doc with a bunch of supporting files and code. I made a few attempts at uploading various things into a Workfront job to preview it but nothing worked.

Hi Tegwyn,

I don't believe this file type is supported in our Proofing tool. This article provides a list of all the file types that are currently supported.
