Does it preserve CSS styling?

Most everyday CSS comes through faithfully — typography, colors, borders, background colors, padding, margins, and the like all render in the PDF the same way they do in a browser. Some of the newer or more complex CSS features render less reliably depending on which converter you're using, with newer ones generally having broader support. The @media print at-rule is widely respected and is the right place to put PDF-specific styles like hiding navigation, switching to print colors, and forcing page breaks.

How does it handle images?

Images get embedded directly into the PDF rather than referenced externally. Browser-based converters fetch images by URL during the render pass, which only works if the images are publicly accessible from where the converter runs. Server-side tools have direct filesystem access and can pull from local paths. For print-quality output, 300dpi images are the bar — anything lower will look fuzzy on paper. For screen-only PDFs, 150dpi is a reasonable compromise that keeps file sizes manageable.

Can I set page size and margins?

Two ways. The CSS @page at-rule lets you declare it directly in the stylesheet — '@page { size: A4; margin: 1in; }' is the most common form. Most converters also expose page size and margins through their UI or API as separate options. Common page sizes are A4 internationally and US Letter in North America, occasionally A3 for larger reports, and 1 inch margins are the conventional default that prints comfortably on either format.

Does it support page breaks?

Yes, through the standard CSS page-break properties. Setting page-break-before: always on a heading forces a new page wherever that heading appears, which works well for chapter starts. page-break-inside: avoid prevents an element from being split across two pages, which matters for tables and figures that should stay together. The newer break-before, break-after, and break-inside properties do the same thing with cleaner naming, and most converters now support both forms.

Web fonts are the trickier case. @font-face declarations with publicly hosted font files usually work, but the converter has to fetch and embed the font during rendering, which doesn't always happen cleanly. Web-safe families like Arial, Times New Roman, Georgia, and Courier are guaranteed to work because they're available on every operating system. For brand-critical typography in customer-facing PDFs, test the output carefully and have a sensible fallback in your CSS so the document still reads acceptably if the custom font fails to embed.

How big can the HTML/PDF be?

Browser-based converters generally cope with HTML up to roughly 50MB, beyond which memory pressure starts producing errors or hanging tabs. Server-side options like Puppeteer, wkhtmltopdf, and WeasyPrint handle much larger documents because they have proper resource controls and can stream output to disk. Complex CSS — heavy use of layered backgrounds, expensive selectors, or thousands of elements — slows the render regardless of which tool you're using.

Is the data sent to a server?

Browser-based converters built on jsPDF and html2canvas run entirely client-side, so the HTML never leaves your machine. Cloud-based PDF services upload your input to their servers for processing, which is faster and produces better output for complex layouts but is the wrong choice for sensitive content. If your HTML contains customer data, financial details, or confidential business material, browser-based or self-hosted converters are the safer route.

About HTML to PDF Converter

The HTML to PDF converter transforms any HTML markup into a downloadable PDF document directly in your browser. Whether you need to archive a web page, generate a report, or create a printable invoice from HTML, this tool handles it without uploading any data to a server.

Your HTML code is rendered using a sandboxed iframe for safe preview, then captured at high resolution using html2canvas and assembled into multi-page PDFs with jsPDF. All CSS styling included in your HTML is fully supported, so tables, colors, fonts, and layouts render faithfully.

Key Features

Live Preview

See your HTML rendered in real-time using a sandboxed iframe. Toggle the preview on or off to maximize editor space when working with long documents.

Full CSS Support

Inline styles, embedded stylesheets, tables, flexbox layouts, and most CSS properties are supported. Your PDF will look exactly like the preview.

Page Size & Orientation

Choose from A4, US Letter, or Legal page sizes. Switch between portrait and landscape orientation to match your content layout.

Custom Margins

Adjust page margins from 0 to 50 mm. Larger margins provide more whitespace for binding or annotations; smaller margins maximize content area.

Headers & Footers

Add optional header and footer text to every page of the PDF. Use placeholder tokens like {page} and {pages} in the footer for automatic page numbering.

100% Client-Side

All processing happens in your browser. No data is uploaded to any server. Your HTML content stays private and secure on your machine.

Common Use Cases

Invoice & Report Generation

Create professional invoices, financial reports, and business documents from HTML templates. Style them with CSS and export as polished PDF files ready for clients or printing.

Web Page Archiving

Save the visual appearance of web content as a PDF for offline reading, compliance records, or legal documentation. The PDF preserves layout, colors, and typography.

Email Template Testing

Preview HTML email templates and export them as PDFs for stakeholder review. Share pixel-perfect mockups without requiring recipients to open an email client.

How to Use HTML to PDF

Paste HTML or upload

Provide the HTML content you want converted. Most tools accept pasted markup, uploaded HTML files, or a URL that the converter fetches and renders. Pasted HTML is the most flexible because it works regardless of where the source page lives — you can pull markup out of a templating system, modify it locally, and run it through the converter without ever publishing it.

Configure page settings

Set the page size and margins based on where the PDF is going. A4 is the international standard at 210 by 297 millimeters; US Letter is 8.5 by 11 inches. One-inch margins are the conventional default for printable documents. Choose portrait or landscape orientation depending on whether your content is more vertical (reports, articles) or horizontal (dashboards, spreadsheet exports).

Optimize for PDF

Add print-specific styles inside @media print blocks before generating. The common adjustments are hiding navigation and footer elements that don't belong in a printed document, switching dark backgrounds to white to save toner, forcing page breaks at chapter boundaries, and ensuring text colors print clearly on paper. A quick test render catches most surprises before they reach customers.

Generate and download

The converter renders the HTML in a real browser engine and captures the result as a PDF file ready to download. The output suits invoices, reports, certificates, archived articles, and any other use case where a customer needs a stable file rather than a live web page. Spot-check the first page or two before sending to make sure fonts embedded correctly and the layout matches what you expected.

When to Use HTML to PDF

Generating reports

Invoices, financial summaries, certificates, and templated reports often live as HTML in the source application but need to land as PDFs in someone's inbox or archive. The conversion preserves layout, colors, and fonts so the result reads the same as the rendered HTML — which matters when the design has been carefully tuned. Common in finance teams sending monthly statements, education portals issuing course completions, and any business tool that prints customer-facing documents.

Web page archiving

Saving a web page as a PDF preserves it offline with formatting intact, which beats screenshots when you want searchable text and beats raw HTML when you want a stable record. Useful for personal bookmarking when the original might disappear, evidence preservation in research and legal contexts, and building a PDF library of articles you actually want to keep.

Document distribution

PDF is the format that renders identically on every operating system and device, so client deliverables, formal letters, and contracts almost always end up in PDF before being sent. Starting from HTML lets you reuse a templated layout and produce branded documents quickly without firing up Word or InDesign for every variation.

Content publishing

Long-form blog content, technical documentation, and tutorial articles can be repackaged as downloadable PDFs for ebooks, lead magnets, and education materials. Marketing teams and educators use this constantly — turn the page you already wrote into a polished PDF, gate it behind an email signup, and you have a content asset for free.

HTML to PDF Examples

Simple HTML page

Input

<html><body><h1>Report</h1><p>Content...</p></body></html>

Output

A PDF with a formatted heading and paragraph using the browser's default fonts and sizing.

The minimal conversion. The tool renders the HTML, captures the rendered output, and writes it to a PDF. Most basic CSS comes through cleanly, and the result preserves whatever layout the browser would have shown — which is usually exactly what you want.

Styled invoice

Input

HTML with company logo, line items, totals, footer

Output

A PDF invoice with logo, table of charges, totals, and footer all preserved in place — ready to email or archive.

The common business use. Generate the invoice as HTML through whatever templating system you have, run it through the converter, and drop the resulting PDF into an email. The output is consistent across customers without manually formatting each one in Word.

Multi-page document

Input

Long HTML article with images

Output

A multi-page PDF with automatic page breaks, embedded images, and optional headers, footers, or page numbers.

Long content paginates automatically — the converter knows when content exceeds a page and splits accordingly. Most tools let you opt into headers, footers, and a generated table of contents for documents that need them. Useful for ebooks, manuals, and long technical writeups.

Tips & Best Practices for HTML to PDF

1.Use @media print rules to optimize for PDF rendering. Hide navigation, switch dark backgrounds to white, force certain elements onto new pages — print styles let you tune the output without affecting the on-screen version.
2.Watch for font issues. PDF doesn't always embed every font cleanly, especially custom ones. Stick to web-safe fonts (Arial, Times New Roman, Georgia, Courier) or carefully test that your @font-face declarations actually embed before relying on them in customer-facing documents.
3.Use higher-resolution images for print-quality output. A 72dpi web image looks fine on screen but prints fuzzy. 300dpi is the print-quality bar; for screen-only PDFs, 150dpi is a reasonable compromise that keeps file size manageable.
4.Set page size and margins explicitly with @page. '@page { size: A4; margin: 1in; }' produces consistent output regardless of which tool generates the PDF. Otherwise different converters apply different defaults and your invoice ends up in Letter on one machine and A4 on another.
5.Skip the animations. PDF is a static format, so CSS transitions and animations contribute nothing to the output and can occasionally produce strange layout artifacts during rendering. Static styles only.
6.For high-volume conversion, move to server-side tools. Puppeteer, WeasyPrint, and wkhtmltopdf handle large batches more reliably than browser-based libraries and give you better control over rendering options. Browser tools are fine for occasional one-offs.

Frequently Asked Questions

The standard markup all comes through cleanly — text formatting, images, links, lists, tables, semantic sectioning elements, and the bulk of CSS for fonts, colors, sizing, and positioning. Where things get less reliable is the modern dynamic stuff. Animations are pointless in a static format. JavaScript usually runs once during the rendering pass but won't execute in the final PDF. Complex Flexbox and Grid layouts mostly work but occasionally produce surprises. Worth testing your specific template before relying on it for production output.
