What do I get back from Add Comments to PDF?

The result is PDF, offered as a download the moment the work finishes. Multiple results come back together rather than as fifty separate save dialogs.

How big a file can I use?

Up to 100 MB per file and 50 files per batch. There is no server queue behind that limit; the practical ceiling is your browser's memory, so split unusually large documents into two runs.

Is it safe to use for a document with personal details in it?

That is the design goal: the document stays on your device, so a statement, a contract or an ID photo is never transmitted for processing. Nothing here needs an internet connection once the page has loaded, apart from engines that fetch their own model data.

What can't Add Comments to PDF do?

Comments are rendered as visible note text baked into the page, not as interactive PDF comment pop-ups. That limit is stated on the page and in the alert above the tool, not buried in a footnote.
