Usage notes

• Files are read from and written to your local disk; results are saved next to the input file unless you pass output_dir.

• Conversions run synchronously over HTTPS; processed files are deleted from Convertica's servers right after the response (details).

• API calls are metered against your plan's monthly quota; failed calls are not counted.

Development

npm install
npm run smoke                        # protocol check, no key needed
