Output

Output	Type	Description
PDF File	File	The rendered `page.pdf` document.

Put print-specific rules in the HTML with @media print. Page size, margins, headers, and footers can be supplied through Additional API Parameters when supported by Cloudflare’s PDF endpoint.

External stylesheets, fonts, and images must be reachable from Cloudflare’s browser. For the most portable document, use absolute URLs or embed the assets directly in the HTML.

Troubleshooting

Fonts or images are missing

Replace local and relative asset paths with public absolute URLs, or embed the asset in the HTML. The remote browser cannot access files on your computer or private network.

The PDF was captured too early

Set Wait For Selector to an element created after rendering finishes, or add a small Wait Time.
