Powered by Chromium Gotenberg clusters, Redis job queues, and Horizon. The service operates completely statelessly (zero disk writes), ensuring maximum security and GDPR compliance.

Frequently Asked Questions

Answers to questions you might have about our HTML-to-PDF REST API, billing, and integrations.

Yes! Every new account starts off with 100 free monthly credits. At the beginning of each billing cycle (exactly 1 month from your registration date), your free credit balance is automatically refilled back to 100 credits at no cost.

If you exhaust your free credits, or need to run larger conversions, you can purchase paid credits. Paid credits never expire. The system automatically consumes paid credits first, and only falls back to your free credits if you run out of paid credits.

Yes, our API fully supports both. You can send raw HTML payloads with inline CSS and JS, or request a conversion of any public URL. The rendering is done using a headless Chromium browser engine to guarantee absolute visual accuracy.

Yes. HtmlToDoc operates entirely statelessly. No document payload, user-submitted HTML, or generated PDF binaries are ever written to the server's hard disk. File operations occur purely in-memory and are streamed back immediately, ensuring absolute data security.
