PDFlib is not a converter, and can not convert HTML fragments to PDF. If you use Textflow, you must translate the HTML attributes into known PDFlib options. Depending on your input data, this can be a non-trivial task.

The Best Way to Generate PDF from HTML Using PDF-lib
October 3, 2024 - Though these tools can be more resource-intensive, they ensure better HTML to PDF conversions. PDF-lib’s strength lies in its control and customization but lacks the robust, out-of-the-box HTML rendering you might need for complex layouts.

create PDF with pdf-lib and display in browser tab
Change this line: download(pdfBytes, "hello.pdf", "application/pdf"); Into this: open(URL.createObjectURL(new Blob(pdfBytes, {type: "application/pdf"}))); Note: web browser application may block new tab from being opened. User must specifically and manually allow the new tab to be opened. This is part of web browser security. The only other way around it, is to present a link for the user to click, where the link will open the PDF in a new tab. e.g. instead of the above changed code, use these: var ele = document.createElement("A"); ele.textContent = "Open PDF file"; ele.href = URL.createObjectURL(new Blob(pdfBytes, {type: "application/pdf"})); ele.target = "_blank"; document.body.appendChild(ele); More on reddit.com

r/HTML on Reddit: create PDF with pdf-lib and display in browser tab
January 6, 2023 -

I've got the pdf-lib part down. I can download the pdf or display it in an iframe. But I just want to display it in a browser tab. I'm pretty sure it's possible and that I'm missing some detail.

see this jsfiddle: https://jsfiddle.net/dreamgear/pzo086kr/5/

What I've tried has to do with the Blob and objectURL stuff commented out at the end.

Apparently I transgressed with the flair thing. I hope this is better.
