The ClipboardItem interface of the Clipboard API represents a single item format, used when reading or writing clipboard data using and clipboard.write() respectively.

The benefit of having the ClipboardItem interface to represent data, is that it enables developers to cope with the varying scope of file types and data.

Note: To work with text see the Clipboard.readText() and Clipboard.writeText() methods of the Clipboard interface.



Creates a new ClipboardItem object, with the MIME type as the key and Blob as the value.

Instance properties

This interface provides the following properties.

types Read only

Returns an Array of MIME types available within the ClipboardItem.

presentationStyle Read only

Returns one of the following: "unspecified", "inline" or "attachment".

Instance methods

This interface defines the following methods.


Returns a Promise that resolves with a Blob of the requested MIME type, or an error if the MIME type is not found.


Writing to the clipboard

Here we're writing a new ClipboardItem() to the system clipboard by requesting a PNG image using the Fetch API, and in turn, the responses' blob() method, to create the new ClipboardItem.

async function writeClipImg() {
  try {
    const imgURL = "/myimage.png";
    const data = await fetch(imgURL);
    const blob = await data.blob();

    await navigator.clipboard.write([
      new ClipboardItem({
        [blob.type]: blob,
    console.log("Fetched image copied.");
  } catch (err) {
    console.error(, err.message);

Reading from the clipboard

Here we're returning all items on the clipboard via the method. Then utilizing the ClipboardItem.types property to set the getType() argument and return the corresponding blob object.

async function getClipboardContents() {
  try {
    const clipboardItems = await;

    for (const clipboardItem of clipboardItems) {
      for (const type of clipboardItem.types) {
        const blob = await clipboardItem.getType(type);
        // we can now use blob here
  } catch (err) {
    console.error(, err.message);
