OpenAPIPostman Converter

In-browser & private

Base URL (optional — overrides the spec's server)

Imported as the {{baseUrl}} collection variable, so you can point the whole collection at another environment from one field.

What you get in Postman

A {{baseUrl}} variable, not a hard-coded host. That is the difference between a collection you can point at staging and one you have to edit forty times. If the spec's server is a bare path — and many are, the Swagger Petstore's is /api/v3 — it is joined onto a placeholder host you can replace in one place.
A folder per tag, matching how the API is documented.
Path parameters become Postman variables. /pet/{petId} is imported as /pet/:petId, so Postman shows it as an editable field rather than literal text.
Example request bodies. Built from the request schema, using the spec's own example or default where it gives one, so a request is runnable rather than an empty shell.
Optional query parameters are added but disabled — visible in the UI as unticked, so you can see what is available without sending empty values.
