DynamicPDF Cloud API vs PDF API

DynamicPDF Cloud API provides cloud tools for creating and manipulating PDF documents through REST endpoints and client libraries. Its PDF endpoint can create or modify documents, merge PDFs, and make pages from HTML, Word, images, or DLEX templates. Other listed operations include stamping PDFs, adding barcodes, filling forms, converting images to PDF, encryption, and retrieving text and metadata. An online document and report designer is included. Client libraries are listed for Node.js,.NET, Java, PHP, Go, Python, and Ruby. The maker says the API processes documents in real time across 10 geographic zones and routes requests to the closest zone. Endpoints use HTTPS and authentication tokens; endpoint data and generated results are not stored unless users choose cloud storage. The maker advises against calling endpoints directly from an end-user browser because exposed API keys can be misused. The free plan includes 1,000 pages per day, 10MB of cloud storage, community support, 10 global endpoints, and a watermark. Basic costs $19.95 a month.

PDF API converts HTML templates and JSON data into PDFs through a cloud REST API. Developers can submit raw HTML or reuse dashboard templates with Handlebars-style variables, loops, and conditionals. Page size, orientation, margins, headers, and footers are configurable, while Chromium rendering supports modern CSS including Flexbox, Grid, and custom properties. Listed uses include invoices, receipts, contracts, financial reports, shipping labels, and tickets. The maker says a persistent Chromium pool and Rust backend generate documents in under 300ms. Webhooks report generation, deletion, and approaching quota limits, with authenticity checked through the X-PDF-Signature header. Generated files use temporary URLs and are removed when a URL expires, by default after 24 hours, or when deleted. Sandbox requests do not count toward quota, but sandbox files are watermarked and purged after one hour. The service is EU-hosted and GDPR compliant. Plans include Free at free for 500 PDFs monthly and paid plans from €15/mo.
