HTML to PDF

The renderer is WeasyPrint, not a headless browser. That’s a meaningful distinction. Headless Chrome renders what a browser would show an interactive user — JavaScript, dynamic content, cookies, login states. WeasyPrint renders static HTML and CSS only. So: if your page requires JavaScript to load its content, the URL mode will produce an empty or sparse PDF. Authentication-gated pages also won’t work — the server can’t log in on your behalf.

What WeasyPrint handles very well is CSS-heavy static markup: print stylesheets, @page rules, Flexbox, Grid, web fonts. If your use case is “turn this invoice template into a PDF” or “generate a PDF from this HTML report,” this is the right engine.

Input modes

Convert URL

Enter any public http or https address; the server fetches and renders it at conversion time. Dynamic/JS-rendered content will not appear.

HTML Files

Upload .html documents. If local CSS files are included in the same batch, they are linked automatically.

HTML Code

Paste or type markup directly. A character counter tracks length; a Clear button wipes the field.

Layout settings

Page Size

One Long Page (no pagination), A4, Letter, or Legal.

Orientation

Portrait or Landscape.

Margin

Standard, Minimum, or None.

Device View

Desktop, Tablet, or Mobile — sets the viewport width sent to the renderer, triggering responsive CSS breakpoints in the source.
