Your App as a Filesystem ​

What is OPFS? ​

The Origin Private File System (OPFS) is a browser-native file system that provides:

  • Private, persistent storage that's invisible to users but accessible to your web app
  • High-performance file operations with direct file handles and streaming capabilities
  • Sandbox security with no cross-origin access concerns
  • Large storage capacity typically much larger than localStorage or IndexedDB quotas

OPFS is perfect for applications that need to handle large files, perform complex file operations, or provide file-system-like experiences in the browser.
