Need to turn HTML pages into PDFs? Want to automate PDF generation in your web app? Looking for a simpler, more secure, and more scalable option than wkhtmltopdf? Try Doppio, a fully managed API for generating PDFs from HTML.

If you need to convert HTML to PDF in your product, wkhtmltopdf or one of its wrappers may seem like the obvious choice. It is free, open source, and still widely used. But it also comes with important limitations. We ran into those limits ourselves, which is why we built Doppio.
Nothing to install, just an API call. Doppio is hosted and secured.
Built for production workloads, including higher volume and concurrent rendering.
Technical support is available to help you.
Using wkhtmltopdf or similar libraries means installing and maintaining extra dependencies on your server. In many setups, that adds operational complexity and can create security concerns.
With Doppio, you do not have to manage any of that infrastructure. It is a managed API service: hosted, maintained, and secured. Setup is fast, integration is simple, and you are only one API call away from your first render.

Wkhtmltopdf is no longer maintained upstream. That means no upstream support, no active product evolution, and more long-term risk if you still depend on it in production.
Doppio, on the other hand, is actively maintained by a team that can answer questions and provide technical support.

Wkhtmltopdf does not handle modern JavaScript reliably. If your pages depend on frameworks such as React, Angular, or Vue, that can become a serious limitation.
Doppio works with any programming language or framework as long as you can make an HTTP request.
