HTML to PDF
Convert a web page to PDF
Converting HTML content to PDF is a fundamental need for developers, content creators, and business users alike. Developers building invoicing systems, report generators, or document export features in web applications need a reliable way to render HTML templates as clean PDF files. Content creators archiving web articles for offline reading or future reference need a way to capture the page layout as a permanent document. Business users generating quotes, receipts, or client-facing documents from HTML templates need PDF output that looks professional and consistent across all devices and printers. LazyPDF's HTML to PDF tool uses LibreOffice to render HTML markup with CSS styling into a paginated PDF document. It supports standard HTML5 elements and common CSS properties including fonts, colors, margins, padding, tables, lists, and basic layout. The resulting PDF is a clean, paginated document free of browser chrome (toolbars, navigation elements), making it immediately suitable for sharing, printing, or archiving. Inline CSS and style blocks are fully supported, and images referenced via absolute URLs or embedded as base64 data URIs are included in the output. The tool is ideal for generating PDF invoices from HTML templates, creating PDF versions of web articles, and producing consistent document output from HTML-based reporting systems. Processing takes place on our secure server over HTTPS, with all content deleted immediately after the PDF is returned to your browser.
How It Works
HTML to PDF converts HTML content into a PDF document using LibreOffice's rendering engine. You provide the HTML markup, and the engine renders it with CSS styling into a paginated PDF. Processing takes place on our secure server, and your content is deleted immediately after the PDF is generated.

Frequently Asked Questions
What HTML and CSS features are supported?
LibreOffice supports standard HTML5 elements and common CSS properties including fonts, colors, margins, padding, tables, lists, and basic flexbox. Advanced CSS features like CSS Grid, complex animations, or JavaScript-dependent layouts may not render as expected.
Can I convert a live website URL to PDF?
This tool accepts HTML markup, not URLs. To convert a web page, you would need to save the page's HTML source code and paste it into the tool. This approach gives you control over exactly what content is included in the PDF.
Will images in my HTML appear in the PDF?
Images referenced via absolute URLs (https://...) may be fetched during rendering. Images using relative paths or data URIs embedded directly in the HTML will also be included. For reliable results, use absolute image URLs or embed images as base64 data URIs in your HTML.
Can I use this tool to generate PDF invoices from HTML templates?
Yes. This is one of the primary use cases for the tool. Design your invoice layout in HTML with inline CSS or a style block, insert the relevant data, and convert it to PDF. The output is a professional-looking document that can be sent to clients or stored as a record.
Does the tool support web fonts like Google Fonts?
Web fonts loaded via @import or link tags from external services may not render if the server cannot access the external font CDN during processing. For reliable font rendering, use web-safe fonts like Arial, Georgia, or Times New Roman, or embed font files as base64 data URIs in your CSS.
What page size is used for the output PDF?
LibreOffice uses A4 as the default page size for HTML to PDF conversion. Content that exceeds a single page will flow naturally to subsequent pages. If you need a specific page size or orientation, you can hint at this using CSS print rules such as @page { size: letter landscape; } in your HTML style block.
Can I control the PDF page margins from my HTML?
Yes. Include a CSS @page rule in your HTML style block to set custom margins. For example, @page { margin: 20mm; } sets 20mm margins on all sides. This is the standard way to control print and PDF page layout from CSS and is supported by LibreOffice's rendering engine.
