About
Doppio.sh is a managed API for converting web pages or HTML into PDF documents and PNG screenshots. It targets developer teams that need consistent rendering without maintaining their own Puppeteer or similar infrastructure. The service provides simple HTTP endpoints to render a URL or template into a document, supports both synchronous responses and asynchronous processing with webhook callbacks, and offers observability through logs to help debug failed calls. For storage and privacy, it can upload outputs directly to a customer-controlled S3 bucket using presigned URLs and states that generated documents expire quickly after processing. The product also includes an HTML template editor, basic ready-to-use templates (including some using Paged.js), and rendering support for modern web features such as webfonts, full CSS, images/SVG, responsive design, charts/graphics, and single-page apps.
