Render once. Reuse everywhere.
Build invoices, reports, proposals, or visual assets as HTML using the same design system you already have, then render polished PDF or image output without rebuilding those templates in a separate stack.
Use case
Website capture for documents, screenshots, and rendered outputs.
Turn live URLs or HTML-driven pages into PDFs and images from a real browser environment. Useful when your output needs web fidelity, not a brittle PDF-generation workaround.
POST /jobs PDF, PNG, JPG output Backed by the Paperplane engine
Rendered to PDF or image
How it works
Capture from a real browser environment.
Send a URL to /jobs. Converterer loads the page in a full browser environment, waits for it to render properly, and returns the output as a PDF or image.
# Render a URL to PDF, get a job ID back instantly. curl -u "$CONVERTERER_API_KEY:" \ https://api.converterer.com/jobs \ -d url="https://example.com" \ -d page_size=A4 # → {"id":"fe748521-5d8f-43d8-9093-7970d2d032d7", "status":"queued"} # Result lands at <your-destination>/fe748521-5d8f-43d8-9093-7970d2d032d7.pdf when done. # Subscribe to a webhook to be notified the moment it’s ready.
This is the same rendering engine that powered Paperplane since 2018, now folded into Converterer.
Common use cases
Where website capture earns its keep.
The sweet spot is any workflow where HTML is the source of truth and the finished output needs to be portable, printable, or easy to share.
Invoice and receipt generation
Build invoices as web pages, then render clean PDFs without fighting low-level PDF layout libraries.
Report generation
Turn dashboards, analytics views, or internal reporting pages into polished PDFs for customers, execs, or ops teams.
Website screenshots
Capture full-page or viewport screenshots for monitoring, QA, competitor review, and visual regression workflows.
Social sharing images
Generate OG images, social cards, and campaign assets from reusable HTML templates and dynamic content.
Web archiving
Create stable PDF records of live pages for compliance, legal holds, historical snapshots, or client documentation.
Proposals and contracts
Compose client-facing documents as branded web pages, then export them as PDFs for sending, signing, or storage.
Output control
Tune the result without changing your source templates.
Page settings
Set paper size, orientation, custom margins, and headers or footers when the output needs to print cleanly.
Modern web support
Render web fonts, SVG, Flexbox, CSS Grid, and JavaScript-heavy pages with the fidelity you expect from a real browser.
Asynchronous API
Submit capture jobs and keep your app or workflow moving while rendering completes in the background.
Batch processing
Run multiple captures in parallel for reporting runs, scheduled archives, or high-volume document generation.
Webhooks
Trigger downstream steps when jobs finish so the pipeline stays reliable without constant polling.
Output formats
Pick PDF, PNG, or JPG depending on whether the workflow needs print-ready documents, crisp screenshots, or lighter previews.
Security
Your source pages and outputs are not hanging around.
Converterer only keeps source pages and generated files for as long as needed to complete the job. Rendering runs on isolated infrastructure, and assets are deleted automatically after delivery.
Get started
Read the docs, then put a real page through it.
Best starting point: send an existing page, invoice, or report URL through the API and check the rendered output against your current workflow.
