Why does it not look like my web page?

Because it is a typesetter, not a browser. It reads your content and sets it cleanly; it does not reproduce your CSS.

Is it safe to paste HTML from a website?

Yes. Only a known set of tags is read. Scripts, styles and attributes are discarded, never executed.

Can it fetch a page by URL?

No. It works on HTML you supply, which means nothing is requested from anywhere on your behalf.

Convert HTML to PDF

Turn HTML you supply into a typeset PDF with real, selectable text.

Nothing to choose — set the options and this will make the document for you.

Runs in your browser

How it works

This typesets the content of your HTML — headings, paragraphs, lists, quotations, code and inline emphasis. It is deliberately not a browser: CSS, layout, tables, images and colours are ignored, so the result will not look like the page does on screen. That is a real limitation, and it buys something worth having. The usual way to convert HTML in a browser is to screenshot the page, which produces a PDF whose text cannot be selected, searched or read aloud. This keeps the text real. Scripts, styles and event handlers are discarded rather than run, so pasting HTML from anywhere is safe.
