Clear Postman Cache on Mac
To clear the cache, remove the temporary system folders used by the app. This process recovers space from the typical 200 MB – 5 GB footprint without touching your primary working directory.

Postman cache folders you can clear
These folders are rebuilt automatically, so removing them does not touch your own files.
Locations are the standard macOS folders Postman uses; some appear only after you use the matching feature.
Understanding the Postman cache
Specific to Postman
The cache consists of network data, compiled JavaScript, GPU shaders, and web content. Clearing these helps if the app starts slowly or if the Cache folder becomes excessively large. These specific temporary files are distinct from your local app data and requested files. Only the designated cache directories should be removed to avoid losing unsynced information.
What happens after clearing Postman
The app will rebuild necessary cache files automatically upon next launch. You may notice a slower first start as these files are recreated. Your sign-in status and preferences generally persist. Since collections and history sync to your account, they remain available provided you were signed in.
