03 / Work Document Conversion API 2020 — present

cloudlayer.io

HTML and URLs to pixel-perfect documents, at scale.

cloudlayer.io is a production-grade document conversion platform that transforms HTML and URLs into pixel-perfect PDF, PNG, and WEBP output. It powers invoicing, reporting, certificates, and automated document generation for businesses across the globe.

The system is built as a distributed, queue-driven architecture — a public API surface, a job coordinator backed by BullMQ, and a fleet of headless rendering workers — engineered for throughput, reliability, and consistent rendering fidelity.

Official SDKs ship for Go, Java, JavaScript, PHP, Python, Ruby, and Rust, making the API a first-class building block in any stack.
