FileReaderSync

The FileReaderSync interface allows to read File or Blob objects synchronously.

This interface does not have any properties.

FileReaderSync.readAsArrayBuffer()

This method converts a specified Blob or a File into an ArrayBuffer representing the input data as a binary string.

FileReaderSync.readAsBinaryString()

This method converts a specified Blob or a File into a DOMString representing the input data as a binary string. This method is deprecated, consider using readAsArrayBuffer() instead.

FileReaderSync.readAsText()

This method converts a specified Blob or a File into a DOMString representing the input data as a text string. The optional encoding parameter indicates the encoding to be used (e.g., iso-8859-1 or UTF-8). If not present, the method will apply a detection algorithm for it.

FileReaderSync.readAsDataURL()

This method converts a specified Blob or a File into a DOMString representing the input data as a data URL.
