Is Chrome Service Worker Cache Safe to Delete?
Yes. Service Worker folders store offline website data and push-notification caches per Chrome profile.
Side effects: Some sites may load slower once; offline PWA data may need to re-sync.
What is ~/Library/Application Support/Google/Chrome/*/Service Worker?
Each Chrome profile (Default, Profile 1, Profile 20, etc.) can have a Service Worker folder with CacheStorage and ScriptCache subfolders. These are website caches, not your passwords or bookmarks. Safe to delete — Chrome's built-in cleaner often misses them, which is why they show up in MacMop scans.
Is it safe to delete?
Yes — ~/Library/Application Support/Google/Chrome/*/Service Worker is generally safe to delete. The data in this folder is temporary and will be recreated by the application when needed.
Before deleting, make sure:
- You don't have any important unsaved work in the related application
- You're not in the middle of a critical task that might need this cached data
- You understand that initial load times may be slower after deletion
What happens after deletion?
Some sites may load slower once; offline PWA data may need to re-sync. The folder will be recreated automatically by the application when needed. This process is typically seamless but may take some time depending on the amount of data that needs to be regenerated.
