This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.
Summary
The URL.revokeObjectURL() static method releases an existing object URL which was previously created by calling window.URL.createObjectURL(). Call this method when you've finished using a object URL, in order to let the browser know it doesn't need to keep the reference to the file any longer.
Syntax
window.URL.revokeObjectURL(objectURL);
- objectURL
- is a
DOMStringrepresenting the object URL that was created by callingURL.createObjectURL().
