Batch Convert Webpages to PDF — Automate at Scale

Example: Single URL conversion with curl

curl -X POST https://api.prettypdfprinter.com/v1/generate/url \
  -H "X-API-Key: your_api_key_here" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com/page-to-convert", "template": "clean"}' \
  --output page.pdf

This sends the target URL to the Pretty PDF API, applies the "clean" template, and saves the generated PDF as page.pdf. Replace your_api_key_here with your actual API key.

import { writeFile, mkdir } from "node:fs/promises";

const API_KEY = process.env.PRETTYPDF_API_KEY;
const API_URL = "https://api.prettypdfprinter.com/v1/generate/url";
const OUTPUT_DIR = "pdfs";

const urls = [
  "https://example.com/docs/getting-started",
  "https://example.com/docs/api-reference",
  "https://example.com/docs/authentication",
];

await mkdir(OUTPUT_DIR, { recursive: true });

for (let i = 0; i < urls.length; i++) {
  const url = urls[i];
  console.log(`[${i + 1}/${urls.length}] Converting: ${url}`);

  try {
    const response = await fetch(API_URL, {
      method: "POST",
      headers: {
        "X-API-Key": API_KEY,
        "Content-Type": "application/json",
      },
      body: JSON.stringify({
        url: url,
        template: "clean",
      }),
    });

    if (!response.ok) {
      throw new Error(`HTTP ${response.status}: ${response.statusText}`);
    }

    const buffer = Buffer.from(await response.arrayBuffer());
    const filename = url.split("/").filter(Boolean).pop() + ".pdf";
    await writeFile(`${OUTPUT_DIR}/${filename}`, buffer);

    console.log(`  Saved: ${OUTPUT_DIR}/${filename}`);
  } catch (error) {
    console.error(`  Error: ${error.message}`);
  }

  // Respect rate limits
  await new Promise((resolve) => setTimeout(resolve, 2000));
}

Run with PRETTYPDF_API_KEY=your_key node convert.mjs. This uses ES module syntax and the native fetch API available in Node.js 18 and later. For older Node versions, use the node-fetch package instead.

Free accounts include 3 PDF conversions per month, which is enough to test the API and verify it meets your needs. Paid plans unlock higher monthly limits and faster per-minute throughput for batch workloads.

When your script hits a rate limit, the API returns a 429 Too Many Requests response. Implement exponential backoff in your code: wait 2 seconds after the first 429, then 4 seconds, then 8 seconds, and so on. Most batch scripts will not hit rate limits if you include a 2-second delay between requests.

For detailed pricing and rate limit information, see the pricing page. For enterprise batch conversion needs with higher throughput, contact support.
