Sorry, I'm a long term Windows user but not very proficient. That can't be there entire contents of the bat file, can it? What else goes in there?
Nope that's it. The bat file here is just a clickable shortcut so you don't have to remember the whole command. The interesting stuff is happening in ImageMagick, which has to be installed already.

In summary you could say yes but I wanted to simplify the process for the not-so-techy person. I will work on a Standalone app that simplifies the command and shows a nice GUI for more private documents
I hope you don’t take the comment you’re responding to as anything negative. I’m a software engineer and I would use this myself rather than try and remember some arcane command line utility.
I find that digital books are simply too perfect. There should be pdf fonts where there are maybe 10 incantations of each character, and the display: 1. picks one incantation randomly for each display 2. slightly and randomly alters the position/rotation of each character 3. adds a tiny blotch now and then Like the print in a real book, especially ones printed before 1970. I also suggest that the background be an act…

Try this one-line ImageMagick command to make COMPACT pseudo-scanned files: convert -density 150 ORIGINAL.pdf -colorspace gray +noise Gaussian -rotate 0.5 -depth 2 SCANNED.pdf Consider using `-depth 1`, `-depth 3` as a final parameter to map colors to only 2¹=2 or 2³=8 instead of 2²=4 gray levels. Using a small number of gray levels SIGNIFICANTLY reduces file size and also gives your pseudo-scanned document a more pi…
Rather than making a COMPACT version, your command created a file over twice the size of one created using the aforementioned convert letter.pdf -colorspace gray \( +clone -blur 0x1 \) +swap -compose divide -composite -linear-stretch 5%x0% -rotate 1.5 as-scanned.pdf However, that may be a useful feature, since many users end up inadvertently creating very large PDFs when scanning.

i feel this, and i think i finally understand why people like vinyl static.
Suggestion: Include some before/after examples
Just downgrading the pdf? Looking for a signature-like part and turns this to pseduo-handwritten characters, maybe changing the color? Something completely different?
Naturally, I did not want to upload a potentially confidential document to some random webservice.
I actually had a pdf file containing several pages of "Lorem ipsum" that I needed for another thing, but I deleted it yesterday because I was done with it.
From the github repo, the site is a wrapper around exactly two shell commands. Instead of uploading your data to an untrusted site, you can run from the comfort and safety of your local computer: convert -density 150 input.pdf -colorspace gray -linear-stretch 3.5%x10% -blur 0x0.5 -attenuate 0.25 +noise Gaussian -rotate 0.5 temp.pdf gs -dSAFER -dBATCH -dNOPAUSE -dNOCACHE -sDEVICE=pdfwrite -sColorConversionStrategy=Lea…

I'd recommend GS after ImageMagick as IM will hugely increase the size of the output due to rasterization!
The above convert command produced credible output only 6KB larger than the input PDF in my limited testing.

I usually sign documents on my iPad but in this case they told me the signature had to be from a pen. COVID and everything means I don't have a printer nor a scanner at home so I developed this to "scan my iPad signed documents" worked like a charm!
What do you use to sign PDFs on your iPad?
