About This HAR to Postman Converter
This converter distills HTTP Archive (HAR) exports into clean Postman collections that are ready to run, document, and share. Built with a mobile-first layout, it loads instantly, works offline once cached, and never uploads your data. Compared with tools shared across developer forums or bundled in heavy desktop suites, this page keeps the process private and trimmed to the essentials: parse, preview, export.
Smart host grouping lets you organise requests by domain automatically. That means faster onboarding when your team works across CDNs, APIs, and microservices. Our optional static asset filter removes noise from CSS, JS, and image calls so you can concentrate on core API endpoints. The live summary table surfaces methods, status codes, and timing so you can triage bottlenecks on the spot.
How to Use
1. Capture the traffic you want to replay in Postman. In Chrome DevTools, open the Network panel, reproduce the flow, right-click anywhere in the waterfall, and choose Save all as HAR with content. Other browsers including Firefox, Edge, and Safari follow the same export pattern.
2. Drag the .har file onto the upload card or paste the HAR JSON into the editor. Once the file loads, pick a host from the dropdown if you want to isolate a specific domain. Leave it on “All hosts” to keep every request.
3. Decide whether to group requests by host and whether static assets should be excluded. Click Convert HAR. The tool gives you a downloadable Postman collection, a copy-to-clipboard JSON payload, a shareable permalink for your option choices, and a CSV digest of the requests for quick spreadsheet analysis.
Tips for Better Collections
Use concise network captures that focus on the flow you actually want to test; trimming the HAR keeps Postman collections lean and reduces LCP when sharing with a team. Combine the CSV summary with performance dashboards to highlight response spikes by URL. Before importing into Postman, tag folders or add descriptions so teammates understand why each call matters. Finally, compare collections across environments by exporting staging and production HAR files—our grouping view makes diffs obvious.
FAQs
Can this converter handle large HAR files?
Yes. The parser streams in the browser and skips static assets by default, so collections stay responsive even beyond 10 MB. For very large captures, toggle off grouping to speed up processing further.
Does the tool run offline?
Once the page loads, every action runs locally—no network calls, no telemetry. Bookmark it, add it to your browser apps, or use it inside corporate air-gapped environments without issue.
What makes this converter different?
Beyond standard HAR-to-Postman conversion, you get per-host grouping, one-click CSV summaries, permalinked settings, and a polished interface tuned for Core Web Vitals. Competitors rarely combine all of those extras in a single lightweight page.
