Vendor sources and our tests are labelled separately. Independent tests that have not been run are not implied.
Is this edition right for your task?
The browser’s built-in PDF reader can open local documents, add annotations and fill supported forms. XFA forms are unsupported. Ink and added text do not establish editing of an existing PDF paragraph or creation of interactive fields. This is an assessment of documented scope; we have not independently run this edition’s task fixtures. Check your required tasks and the official purchase terms before switching.
These are documented capabilities, not an independently tested recommendation. Test non-sensitive copies of your own files before switching. Platform support does not establish support for every operating system version.
