I have, in the past but not recently, run into situations where I need to visually sign something, and the form was rejected when I digitally signed it with MacOS Preview because they required the form be printed, signed, and re-scanned.

This would be helpful in that case.

You’re implying that a bureaucratic process being absurd and extremely archaic means it doesn’t exist?

The primary use case is addressing situations where wet ink signatures are required by a party to a transaction without having to print, sign, and scan a document.

Yes, it is an odd combination of legacy (sometimes regulatory) requirements and modern technology, but there are numerous situations where only wet ink signatures are accepted, and “digital signatures” are not accepted—even though the document is stored in a digital format.

Wet ink signatures are most commonly required in finance / investment / banking transactions. They are sometimes required for B2B transactions. While not as common in the US as in other countries, you can also run into requirements where documents must be signed via wet ink signature under seal (or stamp). Scanning a document with a signature line that has been embossed with a company seal looks somewhat comical and arguably legible (especially if the scan is done with a feed-through scanner) but is required to get business done sometimes.

But it's not a "wet ink signature," it's a PDF. The "wet ink signature" is on a piece of paper that never gets delivered.

It says right there in the description

> For bureaucratic reasons, a colleague of mine had to print, sign, scan and send by email a high number of pages. To save trees, ink, time, and to stick it to the bureaucrats, I wrote this script

Fun?
