How to make OCR PDFs on Windows using Tesseract

It's free, it's easy, it's Tesseract, which is an Optical Character Recognition (OCR) engine that detects text in images and overlays the text onto PDFs. Here's how to do it in as short as a tutorial as possible. Medium amount of technical knowledge is helpful.

Here's what each piece of software is doing:
Tesseract: It's what is actually doing the OCR, and putting the text onto images in PDFs. The problem is that Tesseract only takes images as input, so...
ImageMagick: It converts PDFs into a series of PNG images. The problem is it actually needs...
GhostScript: Which provides the tools and libraries that ImageMagick uses. Then there's...
Python: Basic scripting language that is used to run the script I wrote. And that's...
convert.py: Splits up a PDF into images using ImageMagick, then runs Tesseract on individual images, converting them to OCR PDFs, then uses PyPDF2 to merge the individual PDFs together into one combined, OCR PDF.
