What Is an HTML to PDF Converter?
An HTML to PDF converter transforms web page markup, including HTML elements and CSS styles, into a portable PDF document. This is essential for developers who need to generate invoices, reports, or documentation from web templates. Unlike server-side tools like wkhtmltopdf or Puppeteer, this browser-based converter processes everything locally using html2canvas and pdf-lib, meaning your code never leaves your device.
Whether you are converting a styled email template, a landing page mockup, or a data-rich dashboard, this tool renders your HTML exactly as a browser would display it, then slices the output into properly paginated PDF pages with your chosen dimensions and margins.
How to Convert HTML to PDF Online
- Paste your HTML code into the editor on the left. Include any inline CSS or style tags. The live preview on the right updates instantly so you can verify the layout.
- Choose page settings. Select page size (A4, Letter, A3, or Legal), orientation (portrait or landscape), margin size, and render quality (1.5x draft, 2x standard, or 3x high-resolution).
- Click "Convert to PDF" and watch the progress bar as the tool renders your HTML to a canvas, slices it into pages, and assembles the final PDF document.
- Preview and download. Review the rendered pages in the built-in viewer. Edit the filename if needed, then click Download PDF or press Ctrl+D.
- Convert another file. Click "New Conversion" or Reset to start fresh without reloading the page.

Tips for Best Results
- Use inline styles or style tags. External stylesheets (linked CSS files) cannot be loaded due to browser security. Include all styles directly in your HTML.
- Set explicit widths. For best pagination, design your HTML at around 800px width. The converter scales content to fit the chosen page size.
- Use 3x quality for print. If you plan to print the PDF, select High (3x) quality for sharper text and images. Use Draft (1.5x) for quick previews.
- Avoid page-break issues. Add
page-break-before: alwaysin CSS to force content onto a new page where needed. - Test with the live preview first. If it looks right in the preview panel, it will look right in the PDF.
Browser-Based vs Server-Side Conversion
Server-side tools like Puppeteer, wkhtmltopdf, or Prince XML offer features like header/footer injection, page numbering, and external resource loading. However, they require server infrastructure, cost money at scale, and your HTML is sent to a remote server.
This browser-based approach is ideal when privacy matters, when you need instant results without API calls, or when you are working with self-contained HTML that includes all styles inline. For complex documents with external assets, consider using our Merge PDF tool to combine multiple converted sections.
Frequently Asked Questions
Is my HTML code uploaded to any server?
No. The entire conversion happens in your browser using JavaScript libraries (html2canvas and pdf-lib). Your code never leaves your device.
Why does the URL mode not work for most websites?
Browsers enforce CORS (Cross-Origin Resource Sharing) security policies that prevent loading external websites in iframes. This is a browser security feature, not a limitation of this tool. Use Code mode instead by copying the page source.
Can I use external CSS frameworks like Bootstrap or Tailwind?
You can include the full CSS output (compiled CSS) inside a style tag in your HTML. External stylesheet links will not load due to CORS restrictions. Copy the compiled CSS from your framework and paste it in a style block.
What is the maximum HTML size I can convert?
There is no hard file size limit since processing happens locally. However, very large documents (100+ pages) may be slow depending on your device's memory and processing power. For best performance, keep documents under 50 pages.
How do I control page breaks in the output PDF?
Use CSS page-break properties: page-break-before: always forces a new page, and page-break-inside: avoid prevents an element from being split across pages. Add these to your HTML's style block.
Does this tool support images in the HTML?
Yes, inline images (base64 data URIs) and images from CORS-enabled servers will render correctly. Images from servers that block cross-origin requests may appear blank. Convert images to base64 first using our Image to Base64 tool.
