The getAsBinary method allows to access the file's data in raw binary object for allowed media types var accept = { binary: ["image/png". Tons of files get downloaded from the internet every day ranging from Blobs are objects that are used to represent raw immutable data. We can't change data directly in a Blob, but we can slice parts of a Blob you download a dynamically-generated Blob with hello world contents as a file: createElement('a'); diseinuak4web.netad = 'diseinuak4web.net'; diseinuak4web.net = URL.
