You know what. I will share my script in the morning.

I used scantailor go scan a book. That gave out tif files.

So I built a script to convert them to jpg, then merge into PDF. Then OCR and add the text layer on PDF. Then compress.

I know this for a niche automation..... web OTOH where normies reside and are scared by terminal, it wont work.

Been using pdftk for years now but im only person who can use it in my office.
