A Blob URL is a reference to a blob that is stored by the web browser in memory or on disk. They start with blob:// and have the same origin as the script that created them. Blob URLs are only valid in documents of the same origin.

Blob URLs are not permanent. The URL is not valid after the visitor has closed or left the document whose script created the URL. It is also possible to revoke the validity of a blob URL.
