Project mention: Stirling PDF: Self-hosted, web-based PDF manipulation tool | news.ycombinator.com | 2024-05-02Well it was developed initially by ChatGPT. First file I open I see repeated comments.

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).
I have been creating print labels with plot/cut lines using css and I used browsers to covert it to PDF. The experience was terrible. While all was perfect on my 1-page proof print, both large browsers messed up the final document (with a few hundred labels on several pages).
Firefox forgot to render images after a few pages. So on some labels the barcodes were not printed.
Chrome looked good at the fist glance. But it turned out that the plot/cut lines (which I created via CSS borders) had been shifted by 1-2mm on _some_ pages. Result was garbage.
I finally switched to https://github.com/flyingsaucerproject/flyingsaucer which is a high quality HTML/CSS to PDF library. Only drawback is that it only supports CSS 2.1, so some fancy features are not supported like rotating text.

PDF Converter, can remove password protection altogether if needed & is a great tool, then view in MJ PDF
There are some pdf readers that protect you against those things.
On Android, for example, there is the GrapheneOS Pdf Viewer [1]. It's readme has a pretty good explanation of how it works.
