How to use HTML to PDF Converter
The HTML to PDF converter turns HTML and CSS into a downloadable PDF entirely in your browser. Paste your markup, choose a page size and orientation, and export a PDF with no watermarks and no sign-up. Inline and embedded CSS is applied before the page is captured, and tall content is split across pages automatically. Because everything runs locally, your markup and content are never uploaded.
- Paste your HTML (with any CSS) into the input box.
- Choose the page size, orientation, and a file name.
- Click "Download PDF" to render and export.
- Open the downloaded PDF to check the result.
Your data never leaves your device — 100% private processing.
How client-side conversion works
Your HTML is rendered off-screen with its CSS applied, then captured into a high-resolution canvas and written into a PDF at your chosen page size and orientation. Content taller than a single page is sliced across multiple pages so nothing is cut off. The whole process happens in your browser using a canvas, which means your markup — including any sensitive figures in an invoice or report — never touches a server.
Getting the best results
For predictable output, inline your CSS or include it in a <style> block within the HTML, since externally linked stylesheets may not load in the off-screen render. Use absolute units and avoid relying on JavaScript, which does not run during capture. Because the page is captured as an image, the resulting PDF text is not selectable; if you need selectable text, a server-side renderer is more appropriate, but for visual fidelity this client-side approach is fast and private.
