Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.
Note: This method is deprecated in favor of readAsArrayBuffer()
.
The readAsBinaryString()
method of the FileReaderSync
interface allows to read File
or Blob
objects in a synchronous way into a string. This interface is only available in workers as it enables synchronous I/O that could potentially block.
