GoPDF

What GoPDF is

GoPDF is a managed cloud API for converting HTML content and URLs into PDF documents. It uses Chromium to render PDFs and supports Handlebars templates populated with supplied data. Its PDF operations include batch conversion, merging, watermarking, compression, password protection, and validation. Batch requests can contain up to 50 items, with as many as 10 rendered at once. Reusing an idempotency key within 24 hours returns a cached result. When storage is enabled, converted files can be uploaded and returned by signed URL. A demo API key is available without signup, with a limit of 10 PDFs per day. The free plan costs nothing for 1,000 PDFs per month; Starter costs $9 a month for 5,000 PDFs, and Growth costs $29 a month for 20,000 PDFs. SDK languages listed are Node.js, Python, Go, and Ruby. The agent quickstart includes examples for Claude, OpenAI, and LangChain. The maker describes GoPDF as suited to modern web applications and developer-oriented APIs.
