Best HTML to PDF APIs in 2026

1. PDFGate

PDFGate is our product, so read this entry with that in mind. It converts URLs and raw HTML to PDF with Chrome, then covers the rest of the document workflow in the same API: fillable form fields generated from HTML inputs, processing existing PDFs, and sending documents for e-signature.

Strengths

• Chrome rendering with waiting options for a CSS selector, network idle, or a fixed delay.
• Click selector chains to dismiss cookie banners and pop-ups before capturing a page.
• Fillable PDF form fields, including signature fields, created from HTML inputs.
• Compress, flatten, watermark, protect, and extract form data from PDFs, plus e-signature envelopes, with one API key and one quota.
• Hosted on AWS in the EU (Frankfurt), with SDKs for Node.js, Python, PHP, Java, and C#, no-code integrations, and an MCP server.

Limitations

• No asynchronous generation with webhooks; requests are synchronous.
• No PDF/A or PDF/UA output, and no image output.
• No free plan, only a 14-day trial.

Pricing

• Personal: $9/month for 500 conversions, 3 in parallel
• Starter: $20/month for 3,000 conversions, 5 in parallel
• Basic: $50/month for 10,000 conversions, 10 in parallel
• Overage is $0.05 per conversion on Personal and $0.02 on Starter and Basic. Failed and sandbox requests are not counted.

Best for: Generating, processing, and signing documents in one API. See the HTML to PDF API and pricing.

2. DocRaptor

DocRaptor is built on Prince, a commercial engine designed for print. It is the strongest choice here for documents that rely on CSS Paged Media, such as footnotes, page floats, and different left and right pages.

Strengths

• Advanced print layout from CSS Paged Media.
• Accessible PDFs, PDF/UA, and PDF/A.
• Asynchronous generation with a callback URL, plus hosted document links.
• SOC 2, HIPAA, and GDPR compliance, with a 99.99% uptime guarantee.

Limitations

• Does not support the entire JavaScript ES6 specification, according to DocRaptor, so heavily scripted pages may need extra work.
• The most expensive per document of the code-first APIs on this list.
• Focused on generating PDF and Excel files, without e-signatures or processing of existing PDFs.

Pricing

• Basic: $15/month for 125 documents
• Professional: $29/month for 325 documents
• Premium: $75/month for 1,250 documents
• Overage ranges from 2.5¢ to 12¢ per extra document, depending on the plan.

Best for: Print layouts and PDF/UA. Read the full PDFGate vs DocRaptor comparison.

• Watermarks and password protection during conversion.
• GDPR with EU customer data in France, and a HIPAA mode with a BAA.
• Integrations with Zapier, Make, n8n, and others, plus an MCP server.

Pricing

• Starter: $9/month for 500 credits
• Boost: $24/month for 2,500 credits

4. PDFCrowd

PDFCrowd is a long-running conversion toolkit from the Czech Republic. Beyond HTML to PDF, it converts between PDF, HTML, images, and text, and offers options that many APIs lack, such as PDF/A and built-in templating.

Strengths

• Occasional overages are not charged, but frequent ones require an upgrade.
