Two render modes
Pick desktop (1280px viewport, full layout preserved) or mobile (390px viewport, single-column responsive) before conversion. Most archival use cases want desktop; most reading-on-an-iPad use cases want mobile. The PDF reflects the chosen viewport — same as if you printed from Chrome at that size.
Strip what you don't want in the PDF
By default we keep the rendered page exactly as it appears (minus the print-stylesheet quirks every site has). Optional flags strip cookie banners, sticky headers, sidebars, and ads — useful for archival PDFs where you want the article content, not the marketing furniture. The "clean" preset matches what print-to-PDF would give you with a good adblocker installed.
