Can I try your service for free?

Yes, you can use the free plan with up to 150 conversions per month without requiring a credit card. The service also supports sandbox conversions that do not count toward the monthly quota.

What can I do with your service?

The API allows you to automate conversion of HTML content into high-quality PDFs or screenshots. Practical use cases include generating invoices, reports, tickets, certificates, marketing materials, and QR code documents.

How do you handle data privacy?

Privacy is prioritized through encryption of data in transit and at rest, isolated rendering environments, and stateless architecture. All processing runs on EU-based infrastructure with servers in Germany, and every sub-processor is EU-based. Content is never stored after conversion and never leaves the EU/EEA.

How are conversions counted?

Each PDF or screenshot conversion typically counts as one. For larger files, each 5MB chunk of the resulting file counts as one conversion, so a 14MB file would count as 3 conversions.

What happens if my conversion limit is exceeded?

The service has a friendly overage policy allowing you to use up to 30% of your monthly limit as overage for up to 4 months in any 12-month period. Email notifications are sent when approaching the limit.

What it is

Screenshot of the PolyDoc homepage — polydoc.tech, as visitors see it

PolyDoc is a REST API service that automates the conversion of HTML content into high-quality PDFs or screenshots. The API supports PDF generation with features like PDF/A archival formats, PDF/UA accessibility standards, and e-invoicing (Factur-X and ZUGFeRD). Users can capture pixel-perfect screenshots in multiple formats (PNG, JPEG, WebP) and customize rendering with CSS and JavaScript injection.

The platform includes a dashboard for API key management, template editing with Liquid syntax support, and conversion analytics. Templates allow users to define reusable HTML with variables and loops for dynamic data. Developers can integrate webhooks for asynchronous result delivery or use presigned URLs to upload files directly to their own cloud storage providers including AWS S3, Google Cloud Storage, Microsoft Azure, and others.

PolyDoc emphasizes privacy with EU-based infrastructure (Germany), stateless architecture, encrypted data in transit and at rest, and no file storage after conversion completion. The service offers a free plan with 150 conversions monthly and paid plans starting at $9/month.
