PostScript’s Sudden Death in Sonoma
> ...tools like pdftk have been able to losslessly compress them...
I have had good luck with pdfsizeopt.

PDF/A-3, PDF for Long-Term Preservation, Use of ISO 32000-1, with Embedded Files
The big restriction is that the classic Postscript typefaces are not available (no Times, Helvetica, or Zapf Dingbats), and the PDF file must bundle any fonts it uses.
The pdfsizeopt package will make any PDF smaller, and I think it deletes letters/characters from the included font that are not used.

PDF processing and analysis with open-source tools
This is missing the "pdfsizeopt" suite, that bundles statically compiled utilities to reduce size.
Static compilation means that it will run on most Linux platforms without extra required software.
I believe one aspect of it will remove characters from included fonts that are not used.
It really is quite impressive.

Reducing the Size of Large PDFs
There is a general PDF shrinker, known as "pdfsizeopt" that is bundled with static builds of gs and a number of other utilities.
It cuts some of our PDFs to 10x smaller, mostly by removing unused fonts (but doubtless also some other magic).
The developer asks for donations for production use from those who can afford it.

Highlighting Image Text
We are going to be using an OCR (Optical Character Recognition) engine called Tesseract for the image-to-text recognition part. It is free software, released under the Apache License. Install the engine for your desired OS from their official website. I'm using Windows for this. Add the installation path to your environment variables.

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.
