Free HTML to PDF API

Free HTML to PDF API with 100 free pages and no credit card. Then pay per page with credits that never expire, or self-host for free.

Quick answer. Sign up with your email and open the link we send you to get 100 free pages, then send your HTML to POST https://html-pdf.com/v1/pdf with your key.

curl https://html-pdf.com/v1/pdf -H "Authorization: Bearer $HTML_PDF_KEY" \
  -d '{"html": "<h1>Hello</h1>"}' -o hello.pdf

100 free pages, no card

This section shows how to get a key and make your first PDF in two commands and one click.

# 1. Get a key (or use https://html-pdf.com/login)
curl -X POST https://html-pdf.com/v1/signup -H "Content-Type: application/json" -d '{"email": "you@example.com"}'

# 2. Open the link we email you to confirm (adds the 100 free credits)

# 3. Convert
curl https://html-pdf.com/v1/pdf -H "Authorization: Bearer $HTML_PDF_KEY" \
  -d '{"html": "<h1>Hello</h1>"}' -o hello.pdf

• 100 pages free, one time, no credit card.
• Full API with HTML or URL input, paper sizes, margins, headers and footers with page numbers, and JavaScript rendering.
• Remote MCP server, so Claude, ChatGPT and Cursor can use it too.
• No watermark on free pages.

When the free pages run out, packs start at $10 for 1,000 pages ($0.01/page) and go down to $0.005/page. Unlike monthly plans, purchased credits never expire.

A project that makes 50 PDFs a month can run for years on one small pack.

How free tiers compare

Here is how the free offer stacks up against other APIs. Most HTML to PDF APIs give a monthly free allowance that resets. These numbers are from their pricing pages in October 2026.

A recurring free tier is better if you need a handful of PDFs every month forever. Pay-once credits are better if your usage is bursty or you want to stop worrying about plan limits.

More detail is in PDFShift alternative and DocRaptor alternative.

Free and open-source options

If you want $0 forever and can run a server, these are the tools worth knowing.

• Gotenberg (MIT). A Docker image with Chromium behind an HTTP API. It's excellent, and it's what powers html-pdf.com. See self-host Gotenberg with Docker.
• Puppeteer / Playwright. Script headless Chrome yourself. See Puppeteer HTML to PDF.
• Chrome's CLI. Use chrome --headless --print-to-pdf for quick one-offs. See headless Chrome print to PDF.
• WeasyPrint (BSD). Python with no browser. It has good print CSS support but no JavaScript.
• wkhtmltopdf. Archived and based on an old WebKit, so avoid it for new projects. See wkhtmltopdf alternative.

The cost of "free" is the server. You pay in memory for Chromium (1-2 GB), security hardening for untrusted HTML, updates, and scaling.

If that's not worth your time, 100 free pages and a few dollars of never-expiring credits usually is.

FAQ

Is there a free HTML to PDF API?

Yes. html-pdf.com gives you 100 free pages once, with no credit card and no watermark. You can sign up at https://html-pdf.com/login or with one curl call to /v1/signup.

Do credits expire?

Purchased credits never expire. Packs go from $10 for 1,000 pages to $250 for 50,000 pages ($0.01 to $0.005 per page), and failed renders cost nothing.

How is usage counted?

One credit equals one PDF page. A 3-page invoice uses 3 credits.

What is the best free self-hosted option?

Gotenberg is a solid choice if you can run Docker and give Chromium 1-2 GB of memory. See self-host Gotenberg with Docker.
