Doppio is a managed API that converts HTML, URLs, or templates into pixel-perfect PDFs and PNG screenshots using headless Chromium, without requiring you to run or maintain browser infrastructure.
What is Doppio?
Doppio is a cloud-based document generation service that accepts raw HTML, a public or private URL, or a saved template ID and returns a PDF or PNG screenshot rendered by an isolated Chromium instance. The platform is hosted in the European Union, GDPR-compliant, and built by the Doppio team (no parent company stated). It supports modern CSS (Flexbox, Grid), JavaScript frameworks (React, Vue, Angular), webfonts, charts (Chart.js, D3), and Paged.js for complex print layouts.
Key Features
- Modern Chromium rendering — Full support for CSS3, Flexbox, Grid, JavaScript, webfonts, SVGs, and canvas-based visualizations, ensuring output matches Google Chrome fidelity.
- Direct S3 upload — Render results can be pushed straight to your own S3-compatible bucket via presigned URLs, never transiting through Doppio servers.
- Async + webhooks — Fire-and-forget large batches of renders; Doppio calls back a webhook URL when each document is ready, with extended timeouts for complex pages.
- Template system — Save HTML templates with Paged.js support in a built-in editor, then generate documents by template ID with dynamic data injection.
- Screenshot API — Capture full-page or element-level PNG screenshots with custom viewport dimensions, retinia scaling, and clip regions.
- Privacy-first architecture — Every render runs in a sandboxed Chromium instance that is destroyed immediately after processing; no document content is stored on Doppio servers.
- 99.995% uptime — Claimed SLA based on last year’s performance, with distributed compute clusters handling from hundreds to millions of documents per month.
Who is it for?
- Product and engineering teams — Replace wkhtmltopdf, self-hosted Puppeteer, or fragile PDF libraries with a single API call, removing browser infrastructure maintenance.
- SaaS companies generating invoices, receipts, or order confirmations — Automate branded PDF generation from billing systems and deliver them directly to customers.
- Platforms needing certificates, reports, or archiving — Create personalized certificates at scale, export analytics dashboards as PDFs, or take automated screenshots for compliance monitoring.
What can you do with Doppio?
- Invoices & receipts: Generate branded PDF invoices from your billing system by passing raw HTML or a template ID, with direct S3 upload for storage.
- Reports & dashboards: Export data visualizations (Chart.js, D3) and analytics dashboards as pixel-perfect PDFs for stakeholder reviews or compliance.
- Social media banners: Design marketing visuals using Doppio’s template system and screenshot API to produce PNG files at specific viewport sizes.
- Website monitoring & archiving: Take automated screenshots of public or private pages for visual regression testing, compliance archiving, or competitor research.
How does it work?
- Send your input — Make an API call with a URL, raw HTML, or a template ID. Doppio supports authentication headers for private URLs.
- Chromium renders it — An isolated Chromium instance loads the page, executes JavaScript, waits for network idle, and generates the document.
- Receive the result — The PDF or PNG is returned as a temporary URL, uploaded to your S3 bucket, or delivered via webhook.
