SnapPDF — URL to PDF API

Convert any webpage (or raw HTML) to a PDF with a single API call. SnapPDF renders the page in headless Chromium — CSS, web fonts, and backgrounds included — and returns the PDF bytes. No headless Chrome for you to run, scale, or patch.

HTML to PDF · URL to PDF · webpage to PDF · invoice/receipt PDF · save webpage as PDF

🔗 Live demo + docs: https://snappdf.dedyn.io:8444 ⚡ Get an API key (free tier): available on RapidAPI — see the demo page for the link.

Quick start

Every call is GET /v1/pdf?url=<page> with your RapidAPI key. The response is application/pdf bytes.

Set RAPIDAPI_HOST to the exact host shown on your RapidAPI listing → Endpoints → Code Snippets (it looks like snappdf.p.rapidapi.com).

Node.js

const fs = require("fs");
const HOST = "snappdf.p.rapidapi.com";            // copy the exact host from your listing
const url  = "https://example.com";
const res  = await fetch(`https://${HOST}/v1/pdf?format=A4&url=${encodeURIComponent(url)}`, {
  headers: { "X-RapidAPI-Key": process.env.RAPIDAPI_KEY, "X-RapidAPI-Host": HOST },
});
fs.writeFileSync("out.pdf", Buffer.from(await res.arrayBuffer()));

Python

import os, requests, urllib.parse
HOST = "snappdf.p.rapidapi.com"
url  = "https://example.com"
api  = f"https://{HOST}/v1/pdf?format=A4&url=" + urllib.parse.quote(url)
r = requests.get(api, headers={"X-RapidAPI-Key": os.environ["RAPIDAPI_KEY"], "X-RapidAPI-Host": HOST})
open("out.pdf", "wb").write(r.content)

curl

curl "https://snappdf.p.rapidapi.com/v1/pdf?url=https://example.com&format=A4" \
  -H "X-RapidAPI-Key: $RAPIDAPI_KEY" \
  -H "X-RapidAPI-Host: snappdf.p.rapidapi.com" \
  --output out.pdf

Parameters

Param	What it does
url	the http(s) page to render (required)
format	A4 (default), A3, A5, Letter, Legal, Tabloid
landscape	true for landscape orientation
scale	zoom factor 0.1–2
background	false to omit CSS backgrounds

Common use cases

• Invoices & receipts — render your HTML invoice at a URL, get a print-ready PDF.
• Save / archive webpages as PDF at scale.
• Reports & dashboards exported to PDF on demand.

FAQ

Does it run JavaScript on the page? Yes — it's real Chromium, so client-side JS runs before printing. Use wait_for_selector for content that loads after the initial render.

Do I have to run headless Chrome? No. That's the point — SnapPDF runs it for you; you make one HTTP request.
