PDF rendering server-side using HTML 5 + CSS 3
Are you looking for a way to render PDF's or produce them? If you want to produce PDF's, I've used https://pdfbox.apache.org/ successfully as well as https://itextpdf.com/ (potentially costs money).

How I archived 100 million PDF documents... (Part 1)
So, when I started to view the documents, a lot of them simply failed to open. I had to look around for a library that could verify PDF documents. I had some experience with PDFBox in the past, so it seemed to be a good go-to solution. It had no way to verify documents by default, but it could open and parse them and that was enough to filter out the incorrect ones. It felt a little bit strange just to read the whole PDF into the memory to verify if it is correct or not, but hey I needed a simple fix for now and it worked really well.
- Best FOSS (ideally Docker) that can split PDF files ?

PDF processing and analysis with open-source tools
PDFBox can do this. It’s not part of the CLI but it wouldn’t be too hard to add:

Marker: Convert PDF to Markdown quickly with high accuracy
Last update was pretty recent, and the git mentions tesseract 5 as a dep. so it's likely moved on a bit from when you last tried it:
https://github.com/tesseract-ocr/tesseract/releases
I suppose it depends on your use-case. For personal tasks like this it should be more than sufficient, and won't need user details/cc or whatever to use it.

So You Decided to Extract Recipe Text From Scans of Your Grandpa's Old Cookbook Using Pytesseract (+ My Grandma's Fig Cake Recipe) (+ Hidden Recipes To Be Found)
Install Google Tesseract OCR (additional info how to install the engine on Linux, Mac OSX and Windows). You must be able to invoke the tesseract command as tesseract. If this isn’t the case, for example because tesseract isn’t in your PATH, you will have to change the “tesseract_cmd” variable pytesseract.pytesseract.tesseract_cmd. Under Debian/Ubuntu you can use the package tesseract-ocr. For Mac OS users. please install homebrew package tesseract.

What should I use to take notes in college?
If you go this route, then using an app that can convert your handwritten notes to a digital format (indexed text), will give you a good balance between cognitive processing and efficient data storage/management; you can likely find many such apps on the App Store or Google Play. If you're interested in something more hands-on, on Arch you can probably experiment with Tesseract OCR in an interesting way (Example).
What are some alternatives?
iText - [DEPRECATED] Core Java Library + PDF/A, xtra and XML Worker. Only security fixes will be added — please use iText 7
PaddleOCR - Awesome multilingual OCR toolkits based on PaddlePaddle (practical ultra lightweight OCR system, support 80+ languages recognition, provide data annotation and synthesis tools, support training and deployment among server, mobile, embedded and IoT devices)
OpenPDF - OpenPDF is a free Java library for creating and editing PDF files, with a LGPL and MPL open source license. OpenPDF is based on a fork of iText. We welcome contributions from other developers. Please feel free to submit pull-requests and bugreports to this GitHub repository.
