Converterer
One API for file conversion and website capture.·paperplane.app
Converterer is a REST API for converting files across 300+ format pairs spanning documents, images, audio, and video, and for capturing any website URL as a high-fidelity PDF using headless Chromium. It is used via direct API calls (with code samples in Python, Node.js, PHP, Laravel, Ruby, Go, Java, and cURL) or through no-code automation platforms like Zapier, Make, n8n, and Power Automate. Output can be delivered to built-in storage or directly to a customer's own S3, B2, GCS, or Azure Blob bucket. The product is the rebrand of Paperplane, which launched in 2018 as a website-to-PDF API.
