About converting HTML to PDF

What this tool converts

Two input modes: paste HTML directly into the editor, or upload an .html file. Output is a rasterised PDF — visually faithful but not text-selectable. For vector PDFs with selectable text, use your browser's native print dialog instead (see FAQ).

When to use it

Internal dashboards, financial drafts, contract templates, draft articles, internal documentation — anything where HTML content is sensitive enough that uploading to a third-party converter is the wrong shape.

Privacy framing

Per empirical research, every reachable HTML-to-PDF competitor processes content on their servers (Smallpdf, iLovePDF, PDFCandy, Sejda, PDF24). Adobe ceded the live converter space, redirecting users to Acrobat subscription. The browser-only privacy moat is unoccupied. HTML to PDF runs entirely on your device — markup, fonts, and embedded images stay in your browser.

What we don't handle and why

JavaScript is not executed (security: pasted JS could exfiltrate other tab data). Some CSS features have known rendering gaps: box-shadow, CSS filters, blend modes, position: sticky / fixed. The conversion result will surface notes about which features were affected. For full-fidelity output use the browser print path described in FAQ.

Workflow chain

Combine multiple converted PDFs with Merge PDF. If your source HTML contained <form> elements you'd like to make fillable, use Fill PDF Forms on the converted PDF. Add a password before sharing with Protect PDF.

Frequently asked questions

What HTML elements are supported?
Most standard HTML and CSS — anything your browser can render. Headings, paragraphs, lists, tables, images, inline SVG, basic typography, flex and grid layouts all work.
What's not supported and why?
html2canvas (the rendering library) does not support box-shadow, CSS filters, blend modes (mix-blend-mode, background-blend-mode), object-fit, position: sticky, position: fixed, or repeating gradients. Iframes and shadow DOM are also skipped. The conversion result surfaces a note when any of these are detected.
What if my CSS doesn't render correctly?
Use your browser's native print dialog. Open the HTML in your browser, press Ctrl/Cmd-P, change the destination to "Save as PDF", and click Save. The browser's print path supports the full CSS specification including box-shadow, filters, blend modes, and sticky/fixed positioning.
Are my HTML files uploaded to your servers?
No. All conversion runs in your browser via html2canvas and pdf-lib. The HTML never leaves your device. We have no servers receiving the content.
Can I convert very long HTML?
Yes — up to 500,000 characters when pasted, or 10 MB when uploaded. The output PDF auto-paginates at A4 page boundaries via fixed-height splits. Text or images on the page-break line may be cut; for precise pagination, use the browser's native print path described above.
Does it work with Google Fonts?
Yes, with caveats. We wait up to 5 seconds for web fonts to load before rendering. If the font CDN is slow or blocked, the PDF uses system fallback fonts and surfaces a "Font fallback applied" note in the result.
What about CORS-blocked images?
Images hosted on origins without CORS-permissive headers are skipped — the browser can't paint them into a canvas. A note surfaces in the result. Host images on the same origin as the HTML, or embed them inline as data: URIs to bypass.
Can I convert a webpage by URL?
Not in v1. Browser security (CORS) prevents fetching arbitrary URLs from client-side code. To convert a webpage, open it in your browser, save it as an HTML file (Ctrl/Cmd-S → "Webpage, Complete"), then upload that file here.
