OpenHTMLtoPDF is an open-source Java library for rendering HTML and CSS into PDF documents. It is typically used by developers building server-side document generation into Java applications, such as invoice, report, or statement workflows.

It is based on Flying Saucer and focuses on standards-based HTML-to-PDF conversion rather than WYSIWYG editing or desktop authoring. A distinguishing trait is its Java-centric, embeddable design: teams can generate PDFs directly from application templates without relying on external browser automation or a separate PDF service.
