The HTML-to-PDF API market has grown significantly as teams move away from self-hosted binaries. Here's an honest comparison of the major options available in 2026 — focused on what developers actually care about: integration simplicity, rendering quality, free tier limits, and pricing.
What to Look for in a PDF API
Rendering quality — does it handle modern CSS (Grid, flexbox, custom fonts)? Test with your actual templates, not a Hello World.
Integration simplicity — is there an SDK for your language? How many lines does a basic integration take?
Free tier — enough to develop and test without a credit card.
Pricing — predictable per-conversion pricing or tiered plans.
Reliability — uptime SLA, response time guarantees.
Security — does rendered HTML leave your region? Any data retention?
HTML to PDF API (htmltopdfapi.co)
Full disclosure: this is our service. We've built it specifically for developer ergonomics — clean REST API, first-class PHP/Laravel SDK, and documentation that shows you working code in the language you're actually using.
Free tier: 100 conversions/month, no credit card. Pro: $29/month. Both HTML and URL conversion supported.
Strongest for: PHP, Laravel, any language via REST. Fastest integration path for Laravel shops.
$client = new \HtmlToPdfApi\Client(config('services.htmltopdfapi.key'));
$pdf = $client->fromHtml($html)->paperSize('a4')->generate();
// done — $pdf contains the PDF bytesGotenberg
Gotenberg is an open-source self-hosted PDF API built on top of Chromium and LibreOffice. It's free if you host it yourself. The trade-off: you manage the container, scaling, updates, and uptime. Good option if you have strict data-residency requirements and the ops capacity to run it.
pdfshift.io / html2pdf.app
Several SaaS PDF APIs offer similar REST interfaces. Most have free tiers in the 25–100 conversion/month range and paid plans starting at $9–$29/month. Differentiation is mainly on advanced features (watermarks, password protection, batch processing) and regional data handling.
Recommendation
If you're building with PHP or Laravel, start with HTML to PDF API — the PHP SDK and Laravel documentation mean you'll be generating PDFs in under 10 minutes.
If you're self-hosting and have strict compliance requirements, evaluate Gotenberg.
For any other stack (Node.js, Python, Ruby, Go), any REST-based API works equally well. Pick based on free tier limits and pricing that fits your volume.
