This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage 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 specification changes.
Summary
The URL.revokeObjectURL() static method releases an existing object URL which was previously created by calling 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.
Note: This feature is available in Web Workers.
Syntax
window.URL.revokeObjectURL(objectURL);
- objectURL
- is a
DOMStringrepresenting the object URL that was created by callingURL.createObjectURL().
Example
See Using object URLs to display images.
