About HTML to PDF
An HTML file describes a page, not a sheet of paper: it has no fixed page size, no margins and no page breaks until a renderer decides how to print it. Converting it to PDF means applying a print layout, choosing paper dimensions and letting the layout engine place headings, paragraphs, lists, tables and images onto pages.
This converter renders the file inside your browser tab, stripping scripts, iframes and resources loaded from the network so nothing can run or fetch data during conversion. The result is a set of rendered PDF pages rather than a live web page, which keeps the layout stable but can mean the text in the PDF is part of the page image and not selectable.
What this tool does
Runs entirely in your browser
The HTML file is opened locally and rendered into PDF pages in the tab, so the document is never uploaded or queued.
Print-style page layout
The page is laid out on fixed paper dimensions with margins, so headings, paragraphs and lists flow onto pages instead of one endless scroll.
Tables and inline images kept
Tables, lists, headings and images embedded as data URLs in the document are rendered in the PDF.
External content removed
Scripts, stylesheets, iframes and resources loaded from URLs are stripped, so the PDF shows only what the file itself contains.
10 MB local files
Each HTML file can be up to 10 MB. Processing stays in the tab, so speed depends on your device.
No upload, no account
The file never leaves your device, and no copy is stored on a server.
How to use HTML to PDF
- 01
Add the HTML file
Drop a .html or .htm file onto the workspace or click to browse. The page is read locally in this tab.
- 02
Review what is kept
The workspace lists the supported content: headings, paragraphs, lists, tables and inline data images; scripts and external resources are removed.
- 03
Convert to PDF
Click Convert to PDF and the browser renders the page into fixed PDF pages.
- 04
Download the result
Download the PDF and check the page breaks and that no external content was expected on the page.
- 05
Start over
Use Start over to clear the result and convert another HTML file.

Limitations worth knowing
- Text may not be selectable in the PDF because pages are rendered rather than written with a real text layer.
- External stylesheets, web fonts, scripts and remote images are stripped, so pages that depend on them will look different or lose content.
- JavaScript does not run during conversion, so content generated on the fly by scripts is missing.
- Local processing is capped at 10 MB per HTML file and depends on your browser's memory for heavy documents.
Privacy and file handling
The HTML file is read and rendered entirely inside your browser tab. It is never uploaded to FormatFlow or any other server, no copy is stored, and no network request is made for external resources. Closing the tab discards the input and the generated PDF.
