Transform webpages and HTML code into high-quality PDF documents in seconds. Our HTML to PDF API is completely secure, requires no installation, and is quick to integrate.
From HTML to PDF in Three Steps
Use the converter above in your browser, or call the same service from your own code.
1
Provide your input
Paste HTML, upload a single .html file (up to 5 MB), or enter the address of a public web page.
2
CheapPDF renders it
The page is rendered in a headless browser using the page size you choose, in pixels. Landscape and background printing are optional.
3
Download or integrate
Download the PDF from the converter, or call the API and decode the base64 PDF from the JSON response in your application.
Send HTML, a public URL or an .html file in one POST request and receive the PDF as base64 in a JSON response. Pick your language, copy the example and add your own API key.
Store the key in an environment variable on your server. Do not put it in browser-side code.
The apikey field is missing or not recognised. Check it against your dashboard.

"success": false,
"message": "Invalid API key, please get a new API key from the dashboard",
"error": "invalid_api_key"

See What You Can Create with CheapPDF
Six sample documents built with plain HTML and CSS. Each preview below is the HTML rendered in your browser. Load one into the converter and press Convert to PDF to get the real PDF. All data is invented.
Invoice
Line items, totals and a payment reference in a clean table layout.
Receipt
A compact, narrow layout for point-of-sale or order confirmations.
Certificate
A centered, bordered layout with large type for awards and course completions.
CheapPDF renders your page in a headless browser, so the CSS in your HTML is applied the way a browser applies it. The table lists what we can state with confidence from how the service works.
Practical tips
Inline your CSS in a <style> tag, or link stylesheets that are public.
Use absolute public image URLs, or embed small images as data: URIs.
Set the page width in pixels to match your layout, then test the result.
For pages behind a login, render the HTML on your server and send that HTML instead.
The site is served over HTTPS, and requests to the plain-HTTP address are redirected to HTTPS.
API key checked on every request
The API validates your key before converting. Keep it in a server-side environment variable and never in browser code.
Private addresses are blocked
URL conversions to localhost, private networks and non-standard ports are rejected.
PDFs come back in the response
The generated PDF is returned in the API response as base64. The request log records the time, IP address, user agent, referrer and request path, not the document content.

HTML to PDF API Pricing – Free & Premium Plans
Start free with our HTML to PDF API. Upgrade for unlimited daily conversions for $5/month.
Get answers to common questions about CheapPDF's HTML to PDF API, conversion features, security, pricing, and integration. Learn how to use our API to convert webpages and HTML code to PDF quickly and securely.
What formats do you support for PDF conversion?
We support conversion from any public URL (webpages), raw HTML files (.html/.htm), and pasted HTML code. The output is always a high-quality PDF file, available for immediate download. Our converter handles complex layouts, images, CSS, and responsive designs.
Is my data secure and private on CheapPDF?
Requests are sent over HTTPS, and the API checks your API key on every request. The generated PDF is returned in the response, and the request log records metadata such as time, IP address and request path rather than document content. See the Terms and privacy page for details.
Is CheapPDF really free? Are there any hidden costs?
The web converter can be used without an account. The free plan allows 10 conversions per day, including a free API key. Premium costs $5/month and removes the daily limit. You can cancel anytime.
Do I need to install software or create an account to use CheapPDF?
No installation or account creation required! CheapPDF is 100% web-based. Simply visit our site, paste a URL, upload an HTML file, or paste HTML code, and download your PDF instantly. No downloads, no setup, no hassle.
What are the file size limits for PDF conversion?
HTML file uploads can be up to 5 MB. Web pages are fetched from their public URL. The upload limit is the same on the free and Premium plans.
Can I use CheapPDF's API to integrate PDF conversion into my application?
Yes. CheapPDF provides a REST API: send a POST request with your API key and HTML, a URL or an .html file, and the PDF comes back as base64 in the JSON response. Free accounts get an API key too. See the guides for PHP, Laravel, Node.js and Python.
How long does it take to convert a webpage to PDF?
Conversions are synchronous: the PDF is returned in the same response. Time depends on the size and complexity of the page and any external images or styles it loads. Set a client timeout of about 60 seconds.
Can I adjust the PDF output size and dimensions?
Absolutely! You can customize the width and height (in pixels) for your PDF output. This gives you control over how your webpage is rendered. Common presets are included for convenience, or you can enter custom dimensions.
What browser and devices does CheapPDF work on?
CheapPDF works on all modern browsers (Chrome, Firefox, Safari, Edge) and all devices (desktop, tablet, mobile). Since it's web-based, no special software or plugins are needed. Just open our website and start converting.
How can I get help or report issues with CheapPDF?
Our support team is happy to help! You can contact us through the contact form on our website or email contact@cheap-pdf.com. We typically respond within 24 hours. Check our help documentation for common questions and troubleshooting tips.
What is an HTML to PDF API?
An HTML to PDF API allows developers to programmatically convert HTML content, such as webpages or HTML files, into PDF documents. CheapPDF provides a powerful REST API for this purpose, enabling seamless integration into your applications.
