Why @mdgate/odf

No separate processing service. The converter is TypeScript you can call from Node.js, Cloudflare Workers, Edge runtimes, and browsers.

Local conversion

OTG files can stay inside your application or browser.

Content detection

Recognizes OTG files from their contents, not only the filename.

Deterministic parsing

The same OTG file produces repeatable Markdown without model inference.

Small runtime surface

No Python. No native addons. No WASM. No third-party runtime dependencies.
