Frequently Asked Questions

Everything you need to know about this conversion tool.

wkhtmltopdf is an open-source command-line tool that uses the WebKit rendering engine (the same core as Safari/Chrome) to convert HTML to PDF. It's widely used for invoice generation, report rendering, and web archiving.

Yes. wkhtmltopdf renders CSS3 including Flexbox, Grid (basic), custom fonts, and media queries. CSS print rules (@page, @media print) are honoured for page breaks and margins.

Not automatically. For pages behind authentication, download the HTML source directly and upload the file. Pass any necessary cookies via the options field for basic HTTP auth URLs.

Use CSS page-break rules: `page-break-before: always` or `break-before: page` on any element to force a new PDF page before that element.

Yes — enable "Page Numbers" in the footer option. wkhtmltopdf supports the variables [page] and [topage] for "Page 1 of 10" style footers.

Basic JavaScript executes during a short wait period. Complex SPA frameworks (React, Vue) may not fully render without server-side rendering. For JavaScript-heavy pages, use a headless Chrome approach instead.

HTML to PDF with wkhtmltopdf: CSS Rendering, Page Breaks, and When to Use a Headless Browser Instead

Converting HTML to PDF requires a real browser rendering engine — not just a text parser. wkhtmltopdf uses WebKit, the same engine that powers Safari and early Chrome, to produce pixel-accurate PDF output.

How wkhtmltopdf Renders HTML

wkhtmltopdf embeds a headless WebKit rendering engine. When you provide an HTML file or URL, it renders the page exactly as a browser would — processing CSS, loading linked stylesheets, rendering web fonts, and applying JavaScript (within a short execution window). The rendered page is then paginated according to the specified paper size and exported as a PDF using WebKit's PDF print output pipeline. The result is indistinguishable from printing the page from a browser.

Controlling Page Breaks

Pagination in HTML-to-PDF is controlled by CSS. Use page-break-before: always (or the modern break-before: page) on any element to force a new PDF page. Use page-break-inside: avoid to prevent a table, image, or code block from being split across pages. The @page CSS rule sets margins, paper size, and orientation directly from your stylesheet, giving you precise control without needing to configure the conversion tool separately.

The @media print Rule

Browser-based HTML often has navigation menus, advertisements, and interactive elements that should not appear in print. The @media print CSS rule lets you hide these elements and apply print-specific styles. wkhtmltopdf honours @media print fully — add it to your stylesheet to hide sidebars (display: none), change font sizes, remove backgrounds, and apply print-optimised layouts. This is the recommended approach for HTML templates designed for PDF output.

Handling External Resources

When converting an HTML file, any linked CSS, images, and fonts referenced by relative paths must be included in the uploaded ZIP file. Absolute HTTPS URLs are fetched live during conversion. Google Fonts (loaded via <link> tags) work in URL-capture mode since the server can reach external URLs; for uploaded file mode, embed the font CSS and font files in the ZIP to ensure availability.

Limitations and When to Use Headless Chrome

wkhtmltopdf uses WebKit, which is based on an older version of the browser engine. It does not support modern CSS features like CSS Grid Level 2, container queries, or the latest CSS custom property syntax. Complex single-page applications built with React, Vue, or Angular require server-side rendering to produce static HTML before conversion. For these use cases, a headless Chrome/Puppeteer approach captures the full rendered page including all JavaScript-injected content. EasyConv uses wkhtmltopdf for static HTML and simple JavaScript pages.
