HTML to PDF Conversion: Complete Guide
Converting HTML to PDF is essential for developers generating invoices, designers sharing mockups, and anyone who needs to archive or distribute web content as a document. Our free tool uses your browser’s native rendering engine — the same technology that powers Chrome’s built-in "Print to PDF" feature — for pixel-perfect output.
How Direct PDF Download Works
When you click “Download as PDF”, the tool captures your rendered HTML using html2canvas and packages it into a PDF using jsPDF — both running entirely in your browser. The PDF file downloads automatically — no print dialog needed.
- Google Chrome / Edge: Set Destination to "Save as PDF", then click Save.
- Firefox: Choose "Microsoft Print to PDF" or "Save to PDF" from the printer list.
- Safari: Click the PDF button in the bottom left and choose "Save as PDF".
Controlling Page Layout with CSS
You can control page layout precisely using CSS @page and @media print rules in your HTML:
@page { size: A4; margin: 20mm; }— sets page size and margins@page { size: landscape; }— forces landscape orientation@media print { .no-print { display: none; } }— hides elements in the printed PDFpage-break-before: always— forces a new page before an element
Tips for Best Results
- Use inline CSS or a
<style>tag in your HTML — external stylesheet URLs may not load during PDF generation. - Avoid JavaScript-dependent dynamic content — scripts do not execute during PDF generation.
- For complex multi-page documents, test with
@media printstyles to ensure clean page breaks. - After saving, compress large PDFs with our PDF Compressor.
