Swagger to Postman Converter
Paste a Swagger or OpenAPI JSON spec and convert it into a ready-to-import Postman collection. Runs entirely in your browser.
🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.
Postman collection
{
"info": { "name": "API Collection", "schema": "..." },
"item": [
{ "name": "List users", "request": { "method": "GET", "url": "{{baseUrl}}/users" } }
]
} Example shown — replace it with your own Swagger/OpenAPI spec.
How it works
- Paste your Swagger or OpenAPI JSON spec.
- Every path and method is mapped to a Postman request.
- Download the result as a Postman collection file.
Conversion walks each path in the spec's paths object,
creates a matching Postman request item with the right method, URL,
and parameters, and wraps them all in a Postman Collection v2.1
structure ready to import.
FAQ
Is my API spec uploaded anywhere?
No. Conversion happens entirely in your browser — your Swagger/OpenAPI file is never sent to a server.
Which Swagger/OpenAPI versions are supported?
OpenAPI 3.0 and Swagger 2.0 specs both convert, mapping each path and method to a Postman request.
Does it preserve request parameters and bodies?
Yes — path parameters, query parameters, and request body schemas from the spec are carried into the matching Postman request.
Can I import the result directly into Postman?
Yes — the output is a valid Postman Collection v2.1 JSON file, ready to import via Postman's "Import" button.
How we compare
| Feature | Online Tool Store | Postman's built-in import | Manual request building |
|---|---|---|---|
| No Postman account needed to convert | ✓ | Requires the Postman app open | ✓ |
| Free, no setup | ✓ | ✓ | Tedious for many endpoints |
Postman's own import needs the desktop app open. Swagger to Postman Converter produces the same collection file standalone, ready to import wherever you're working.
