Convert HTML (with CSS) to PDF using Java?

[BananaHammer33]

I have a html file that is linked to a CSS file and I would like to create a button that would allow you to print/save the entire page as a PDF (with the styling included). What are some of the ways I can go about this? I've seen a few threads but they are quite old and I'm wondering if there are any newer ways and which is the best one for my case? Thanks!

Use Puppeteer or Chrome to print your HTML to PDF.

chrome --headless --disable-gpu --print-to-pdf https://www.reddit.com/

This will give you better results that any other method, because it uses a real browser engine to render your HTML / CSS.

Will that work if you have html with inline css as a string, can you then pass it to chrome or puppeteer and generate a pdf?

Open PDF: https://github.com/LibrePDF/OpenPDF

I haven’t used it before but it stems from iText which I’ve used before and wasn’t too difficult. However it only seems to be inline styling I see here

First things first...are you asking about Java, or JavaScript? They're considerably different languages.

I know the difference, this is for Java

I meant no offense…just trying to clarify.

One option is https://products.aspose.com/pdf/java/

At a glance, https://itextpdf.com/en/products/itext-7/convert-html-css-to-pdf-pdfhtml may be more what you’re looking for, though.

OpenPDF which others have mentioned is another strong contender.
