Maker here. This exists because numbering a production set is a mechanical chore with non-mechanical stakes: the numbers have to be continuous across every file, and the files are usually under a protective order, so "upload your folder to our server" is not an available answer. So there's no upload step at all. pdf-lib rewrites each PDF inside your tab and writes the finished files into a folder you choose. Two consequences I like: the privacy claim is checkable rather than promised — load the page, go offline, run a batch, it still works — and the tool doesn't get slower because your set is large. Stated plainly: if you already pay for Acrobat Pro, its batch sequence does the numbering and you don't need this. It's for the machine without that subscription, the Mac, or the set that can't be uploaded. No OCR and no redaction either. Free is one file up to 25 pages with everything enabled, because the only thing that matters for this kind of tool is whether the output is acceptable on your own document. $19 once for unlimited, no account. Would like to hear which legend or numbering format your firm needs that isn't there.
