Questions tagged [fileapi]

Use this tag for questions related to the W3C File API. The W3C File API specifies how file objects should be represented and how their properties should be accessed.

The W3C File API at https://w3c.github.io/FileAPI/ specifies how file objects should be represented and how their properties should be accessed.

The File API spec includes the following interfaces:

  • Blob - raw binary data. Blob objects can be created via the Blob() constructor, but their properties are read-only.
  • File - a specific type of Blob with additional read-only properties.
  • FileList - a collection of File objects.
  • FileReader - provides asynchronous access to a content of a Blob or File object.
