The case for in-process PDF generation
NextPDF runs inside your PHP process. That deployment topology shapes how you scale, secure, and test the documents you produce.

Rendering PDFs at the edge with Cloudflare Workers
The NextPDF Cloudflare adapter turns a Worker into an edge rendering endpoint your PHP app can call, with SSRF hardening and custom fonts from R2.
Validate your PDF output yourself
Published PDF standards samples pair downloadable output with local validator commands. The workflow uses veraPDF and qpdf.
Why we built a PDF 2.0 engine for modern PHP
PHP has had PDF libraries for twenty years. NextPDF combines PDF 2.0 output, tagged accessibility, and PAdES signatures in one in-process, strictly typed engine. It produces the requested result or returns a typed failure.
Typed failures for precise PDF output
NextPDF uses typed failures and fail-closed defaults to define clear boundaries for unsupported operations.
