> HTML can easily be offline-able. Base64 your images or use SVG, put your CSS in the HTML page, remove all 2-way data interaction, basically reduce HTML to the same performance as PDF and allow it to be downloaded.
I built a tool for this exact purpose[0] since the HTML specification and modern browsers have a lot of nice features for creating and reading documents compared to PDF (reflow and responsive page scaling, accessibility, easily sharable, a lot of styling options that are easy to use, ability for the user to easily modify the document or change the style, integration with existing web technologies, etc.). In general I would rather read an HTML document than the PDF document since I like to modify the styling in various ways (dark theme extensions in the browser for example) which may be hard to do with a PDF, but its more of a personal preference. Some people will prefer that the document adjusts to the screen size of the device (many HTML pages), and others will prefer the exact same or similar rendering regardless of the screen size (PDF).
Either way, kind of a fun idea making a website using just PDFs. Not the most practical choice, but fun none-the-less.
