PDFMonkey

PDFMonkey is a cloud document-generation API that turns templates and dynamic data into files. Templates can be built in a visual drag-and-drop editor or written in HTML, CSS, and Liquid; JSON data can be sent through the REST API to generate documents. Its Chrome-based renderer supports JavaScript, external fonts, images, charts, and other web technologies. Outputs include PDF, PNG, WebP, and JPG, and bulk generation from datasets is supported. Connectors include Zapier, Make, n8n, Workato, Bubble, Glide, and InvoiceBerry; developer tools include Ruby and Node.js SDKs and webhooks. API traffic uses HTTPS/TLS, dynamic data is stored in encrypted database columns, and generated files are kept in private S3 buckets with one-hour presigned URLs. PDFMonkey states that it has no formal SOC 2 or ISO 27001 certification. The free plan allows 20 documents per month with one-day retention and a 30-second generation limit, and excludes external images, fonts, CSS, and JavaScript. Paid plans start at €5/mo.
