APITemplate.io generates PDFs and images from reusable templates via API. See 2026 pricing plans, features, and use cases for developers and marketers.
APITemplate.io is an API-first platform for generating PDF documents and images from reusable templates. Instead of writing custom rendering code, users design a template once, in either a visual WYSIWYG editor or raw HTML and CSS, and then call an API endpoint with dynamic JSON data to produce a finished file on demand.
Founded in 2020 by Jacky Tan and based in Singapore, the platform is built for developers and product teams who need to automate document or image creation as part of a larger application, such as generating invoices, certificates, contracts, reports, or social media graphics automatically.
It supports both instant, synchronous file generation and asynchronous batch generation with webhook callbacks, making it suitable for both real-time, single-document requests and large bulk-generation jobs.
Templates can be built visually with a drag-and-drop WYSIWYG editor, or coded directly in HTML and CSS for full design control, with a real-time preview so designers can see changes before publishing a template.
Dynamic data merging lets templates pull in variables such as customer names, order totals, or dates from a JSON payload, so the same template can produce thousands of unique documents or images.
The platform includes official SDKs for Python, C#, Java, PHP, and JavaScript, plus integrations with Zapier, Make, and n8n, and higher-tier plans add CDN-backed file storage, custom CSS, async webhook delivery, team collaboration, and AWS S3 export.
APITemplate.io offers a free plan with 50 PDFs and 3 templates per month, useful for testing and very small-scale use.
Paid plans split into a PDF-only track (PDF Basic at 19 dollars per month for 3,000 PDFs and 20 templates, PDF Standard at 69 dollars per month for 12,000 PDFs and 180 templates) and a combined PDF-plus-image track (Starter at 29 dollars per month for 1,500 documents, Standard at 69 dollars per month for 9,000 documents, and Enterprise at 139 dollars per month for 20,000 documents with unlimited templates and AWS S3 integration).
Monthly billing carries a premium of roughly 15 to 29 percent over annual billing, so teams with predictable volume can save meaningfully by committing annually.
PDF documents such as invoices, certificates, contracts, and reports, as well as images such as social media graphics and product cards, all from reusable templates.
No, templates can be built with a visual WYSIWYG editor, though HTML and CSS are also supported for advanced customization.
