The two API definition formats overlap, but Postman is better for more runtime needs, where OpenAPI tends to have some advantages for working with an API at other stops along the API lifecycle. OpenAPI has an advantage over Postman Collections mostly because of the tooling that has emerged to work with the specification. Postman does a superb job serving a handful of stops, but OpenAPI has a wider availability for the tooling that has been developed.
APITransform offers a free online service that allows developers to convert their Postman Collection to OpenAPI spec.
