APITemplate.io alternative: html-pdf.com

APITemplate.io alternative that renders your own HTML or any URL, billed per page with prepaid credits that never expire. No monthly plan.

Quick answer. Send your finished HTML to POST https://html-pdf.com/v1/pdf and the PDF comes back in the response. There's no template to create first, and you buy pages once instead of a monthly quota.

curl -X POST https://html-pdf.com/v1/pdf \
  -H "Authorization: Bearer $HTML_PDF_KEY" \
  -H "Content-Type: application/json" \
  -d '{"html": "<h1>Certificate</h1><p>Awarded to Ada Lovelace</p>", "landscape": true}' \
  -o certificate.pdf

APITemplate.io is template-first. You build a template in its editor and send JSON data to fill it, and it also makes images from the same templates. html-pdf.com is HTML-first and PDF-only.

Prices checked October 2026 on APITemplate.io's pricing page. PDF plans: Free (50/month), PDF Basic $24 (3,000), Standard $89 (12,000), PDF Enterprise $179 (25,000). Image and PDF plans start at $35 for 1,500. The page doesn't say whether unused quota carries over.

How the prices compare

Both models make sense for different volumes. APITemplate.io's PDF Basic plan is $24 a month for up to 3,000 documents, which is cheap per document if you use most of it every month.

html-pdf.com sells 3,000 pages for $25, once. If you use 3,000 pages a month, every month, the two cost about the same for one-page documents. If you use 300 a month, a $25 pack lasts ten months instead of being billed ten times.

Long documents favor per-document billing. Short documents and uneven volume favor prepaid pages.

When APITemplate.io is the better choice

APITemplate.io wins in these cases.

Non-developers edit the templates in a visual editor.
You also need images (social cards, banners) from the same templates.
Your PDFs are long and you use most of your quota every month.

When html-pdf.com is the better choice

html-pdf.com wins in these cases.

You already have HTML, from your app, an n8n Code node or an AI agent. There's nothing to recreate in another editor.
Your volume is uneven. Prepaid pages don't expire, so quiet months cost nothing.
AI agents make the documents. Connect Claude, ChatGPT, Cursor or VS Code to https://html-pdf.com/mcp and ask for the PDF.
You want to convert web pages. Send {"url": "https://..."} for any public page.
You'd rather not store documents. HTML is never kept. PDFs are kept for 24 hours only when you ask for a link.

Moving over

This section shows the switch in an automation tool. Where you mapped fields into an APITemplate.io template, build an HTML string instead, then call html-pdf.com.

Pick a starting layout from the templates, or ask an AI assistant to write one.
In n8n, a Code node fills the HTML with your data. In Make or Zapier, paste the HTML into the request body and map the fields inline.
An HTTP request posts {"html": "...", "response": "url"} to https://html-pdf.com/v1/pdf with your key. The url in the response is a 24-hour download link for email or Drive steps.
