To create a PDF from HTML with PDFShift in Node.js, send a POST request to https://api.pdfshift.io/v3/convert/pdf, authenticate with your X-API-Key, and pass the HTML in the JSON source property. The response contains PDF bytes; write those bytes to a file such as result.pdf. Use raw HTML for generated or private markup, or provide a URL when PDFShift can fetch the page for you.
Convert HTML to a PDF with Node.js
The example below uses SuperAgent, which PDFShift documents for Node.js. It reads the API key from an environment variable, submits a small HTML document, and saves the response body as a PDF.
const superagent = require('superagent');
const fs = require('node:fs');
const apiKey = process.env.PDFSHIFT_API_KEY;
if (!apiKey) {
throw new Error('Set the PDFSHIFT_API_KEY environment variable.');
}
const html = `<!doctype html>
<html>
<head><meta charset="utf-8"><title>Example</title></head>
<body><h1>PDFShift from Node.js</h1><p>Generated from HTML.</p></body>
</html>`;
async function main() {
const response = await superagent
.post('https://api.pdfshift.io/v3/convert/pdf')
.set('X-API-Key', apiKey)
.send({ source: html });
fs.writeFileSync('result.pdf', response.body);
console.log('Saved result.pdf');
}
main().catch((error) => {
console.error('PDF conversion failed:', error.message);
process.exitCode = 1;
});Install SuperAgent in the project before running the script. Set PDFSHIFT_API_KEY in the environment rather than hard-coding a secret or committing it to source control. The request uses the documented endpoint and key header; the file-writing step stores the returned PDF response bytes.
Choose raw HTML or a URL
| Input | Use it when | What PDFShift must access |
|---|---|---|
Raw HTML in source |
Your application has generated markup, the document is private, or you want to control the HTML and its rendering inputs. | The HTML in your request and any external resources referenced by it. Inline CSS and JavaScript where practical to reduce additional resource requests. |
A page URL in source |
The page is reachable by PDFShift and having the service fetch it fits your workflow. | The specified page and its dependent resources. |
PDFShift’s raw-HTML guide recommends sending a raw document: this avoids a fetch of the source page itself and lets you submit markup that is not publicly accessible. The guide also recommends inline styles and scripts when practical to reduce external requests and loading time. That is vendor guidance, not a measured guarantee of a particular conversion-time improvement.
#1 Best Overall
- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.
- Convert USB-A Ports to USB-C: Designed to connect USB-C earphones, cables, flash drives, card readers, and other USB-C accessories to standard USB-A ports. Plug-and-play with no drivers or software required.
- Aluminum Alloy Housing: Built with a sturdy aluminum alloy shell that aids in heat dissipation and protects against daily wear and scratches. Designed to maintain a stable and secure connection.
- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
For URL input, PDFShift’s Node Axios guide places the URL in source and writes the response data to a PDF file. Do not use URL mode for an address the service cannot reach; use raw HTML when the application owns the markup or the source page is private.
Request, output, and client choices
- Endpoint:
https://api.pdfshift.io/v3/convert/pdf. - Authentication: send the API key in the
X-API-Keyheader. - Input: provide either raw HTML or a page URL as the
sourcevalue. - Output: treat the successful response as PDF data and write its bytes to a file with a
.pdfextension.
The official Node guide index lists examples using Axios, Bent, Got, Needle, NodeFetch, SuperAgent, and Unfetch. Choose a client already used in your application; the documentation does not establish that one is universally faster or better. The raw-HTML example above follows the SuperAgent approach.

If your goal is a screenshot or a PDF capture of a live webpage rather than a PDF created from supplied HTML, ScreenshotNeo offers a one-request alternative. It is a website screenshot API and MCP server for developers; it does not replace PDFShift’s raw-HTML-to-PDF workflow.
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpSee the ScreenshotNeo documentation for request options. Cookie and consent banners, newsletter popups, and chat widgets can be removed before capture. Bot checks, blank pages, failed loads, timeouts, and cache hits are not billed. An MCP server provides screenshot tools for AI agents, including Claude, Cursor, and other MCP clients. The Free plan includes 1,000 screenshots per month with no card; paid plans start at $5 for 3,000 shots. Learn about ScreenshotNeo, then sign up free.
Limits and cost to check before deploying
On the PDFShift pricing page accessed October 3, 2026, the Free plan lists 50 credits per month, a 15 MB maximum file size, and a 30-second timeout. PDFShift counts one credit per 5 MB of generated data. These are plan details shown on that date, not permanent limits; check the current PDFShift pricing page before relying on them.

Troubleshooting PDF conversion
Missing images, fonts, or styles
Inspect whether the markup references external resources and whether those resources are reachable during conversion. PDFShift’s Help Center has dedicated guidance on missing images and custom fonts; consult the relevant help article for remedies specific to the asset or font involved rather than assuming the HTML file alone contains everything needed.

Content overlaps a header or footer
PDFShift’s Help Center identifies page content spilling beneath headers or footers as a support topic. Review the header/footer layout and page spacing, then use the specific support guidance if the content still overlaps. The guide index alone does not establish a universal margin value.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
A chart or other element is absent
For content rendered after the initial page load, PDFShift lists waiting for a page element, such as a chart, among its support topics and offers a tutorial for waiting for a custom element. Use that documented feature when a page needs time or a specific element to appear before conversion; a fixed delay is not guaranteed to fit every page.

The request fails or runs into a plan limit
- Check that the API key is set and sent in the
X-API-Keyheader. - Confirm that
sourcecontains the intended raw HTML or a URL the service can access. - Check the current plan’s file-size and timeout limits if a conversion is large or slow.
- For credit questions, consult PDFShift’s Help Center topic on credit counting and the current pricing page.
The Help Center index also covers conversion time and sensitive documents. Use its dedicated guidance for documents that contain confidential material; do not assume the index itself specifies a particular retention or security policy.

Can I convert a private HTML document?
Yes. Send the HTML itself in source instead of asking PDFShift to fetch a page URL. This is the documented raw-HTML approach.
Does PDFShift require SuperAgent?
No. Its Node guide index includes examples for several HTTP clients, including Axios, Bent, Got, Needle, NodeFetch, SuperAgent, and Unfetch. The essential request uses the documented endpoint, API-key header, and source input.
Can ScreenshotNeo convert raw HTML into a PDF?
ScreenshotNeo’s documented options include HTML/CSS-to-image and PDF capture of webpages. The supplied product details do not establish that it accepts arbitrary raw HTML as PDFShift’s source does.
