Can this tool convert full Postman collections with nested folders?

Yes. It recursively reads nested Postman items and generates cURL commands for each request discovered in the collection tree.

Does this Postman to cURL converter support bearer token and API key auth?

Yes. Common auth types such as bearer token, basic auth, API key, and inherited auth settings are supported when present in exported JSON.

Is my Postman JSON uploaded anywhere?

No. All conversion is browser-side, so your data stays on your device.

Can unresolved {{variables}} be preserved in generated cURL?

Yes. Variables are resolved when values are present in the export. Unresolved variables are preserved so you can replace them manually.
