html2pdf.app is a lightweight HTML to PDF conversion API: you send an HTML string or a URL and it returns a PDF, with full CSS customisation, a WordPress plugin and an online converter, priced by monthly credits. It is a pure conversion tool, which makes it a very different offer to PDF Generator API. The comparison below breaks down where each fits.
Pricing
html2pdf.app is a conversion API billed by monthly credits, from a free tier up to $39/month, with no template editor; PDF Generator API is a document generation platform from €8/month with a 14-day free trial, a drag-and-drop editor, and dedicated or on-premises deployment.

Conclusion
html2pdf.app is a solid, low-cost choice when you already have HTML templates in your codebase and simply need to render them to PDF at scale, with a generous free tier and straightforward per-credit pricing. Its model is pure conversion: there is no drag-and-drop template designer, no fillable PDF form fields, no web forms, no multi-tenant workspaces and no HIPAA or ISO 27001 certification, so the entire template layer stays your responsibility.
PDF Generator API gives you the same HTML to PDF power plus a cloud SaaS from €8/month with a 14-day free trial and dedicated or on-premises deployment when you need it, a drag-and-drop embeddable editor your own customers can use, fillable PDF form and signature fields, web forms, an AI template builder, and HIPAA and ISO 27001 compliance. If you need more than conversion, it is worth a direct comparison.
