The PDF Looks Different From the Browser
Check viewport width, print media rules, page size, margins, and responsive breakpoints. A browser screenshot and a paginated PDF are not rendered under identical constraints.
Fonts Are Missing or Different
Make sure web font files are reachable, allowed by CORS, and loaded before rendering. Fallback fonts can change line heights, page breaks, and text wrapping.
Images or CSS Are Missing
Relative paths, private assets, blocked domains, lazy loading, and scripts that inject content late can all cause missing output. Use absolute URLs or inline critical styles when practical.
Page Breaks Are Bad
Use CSS break rules and print-friendly layout. The CSS in HTML to PDF guide covers the main controls.
Best Recovery Path
Simplify the HTML, confirm assets load, then run HTML to PDF again. For the full setup, return to the HTML to PDF guide.
