How to Convert a Web Page or HTML to PDF

A web page is a living thing — it can change, go offline, or render differently on someone else's browser. A PDF is a snapshot: whatever it looked like at the moment you converted it is what everyone who opens it will see. That's the whole reason to convert a page or a block of HTML to PDF — you're trading "live" for "permanent and portable."

Two ways in: a URL, or raw HTML

Paste a public URL and the tool fetches and renders that page as it currently appears. Or paste raw HTML directly — useful if you've built a report, invoice, or email template in code and want a printable version without publishing it anywhere first. Both paths produce the same kind of PDF; the only difference is where the markup comes from.

Why this needs a real browser on the server

Accurately laying out HTML and CSS — fonts, flexbox, media queries, the works — is exactly what a browser engine is built to do, and it's not something that can run headlessly inside another browser tab. This conversion sends your URL or HTML to a headless browser running on the server, which renders it and prints the result to PDF; the content is discarded once the job finishes. If privacy is a concern, keep in mind this is different from this site's purely client-side tools — the page content does pass through the server to get rendered.

What doesn't survive the conversion

Static content — text, images, CSS styling, tables — comes through accurately. What doesn't: interactive elements. Forms, buttons with click handlers, and anything that requires user input become inert, static markup in the PDF. Embedded videos typically show as a static frame rather than something playable. And pages that require a login render as their logged-out state, since the converter has no credentials for other sites.

How to convert HTML or a URL to PDF

  1. Open the HTML to PDF tool and either paste a URL or paste raw HTML.
  2. Set page size and margins if you need something other than the defaults.
  3. Convert and download the resulting PDF.

For predictable page breaks, add page-break-before: always; to the HTML elements where you want a new page to start.

When you're starting from a document, not a web page

If what you actually have is a Word, PowerPoint, or Excel file rather than HTML, skip this tool and use Office to PDF instead — it converts those formats directly without going through HTML at all.

Frequently asked questions

Does this upload my HTML or visit the URL from a server?

Yes — turning HTML/CSS into an accurately laid-out PDF needs a real browser engine, so a headless browser on the server renders the page and prints it to PDF. The content is discarded once the job finishes.

Will JavaScript on the page still run?

The page loads and renders once, so scripts that run on load will fire, but nothing interactive survives into the PDF — buttons, forms, and click handlers become static, non-functional elements.

Can I convert a page that requires a login?

No. The server has no credentials for other sites, so paywalled or authenticated pages will render as their logged-out state, if they render at all.

Can I control page size and margins?

Yes — set page size (Letter, A4, or custom) and margins before converting, or control them directly in your HTML with CSS `@page` rules.
