The read() method of the Clipboard interface requests a copy of the clipboard's contents, delivering the data to the returned Promise when the promise is resolved. Unlike readText(), the read() method can return arbitrary data, such as images. This method can also return text.

To read from the clipboard, you must first have the "clipboard-read" permission.

Note: The asynchronous Clipboard and Permissions APIs are still in the process of being integrated into most browsers, so they often deviate from the official rules for permissions and the like. Be sure to review the compatibility table before using these methods.





Return value

A Promise that resolves with an array of ClipboardItem objects containing the clipboard's contents. The promise is rejected if permission to access the clipboard is not granted.


Reading image data

This example uses the read() method to read image data from the clipboard.

Try copying the butterfly image on the left using the "Copy image" context menu item, then click in the empty frame on the right.

The example will check or ask for permission to read the clipboard, then fetch the image data and display the image data in the empty frame.

Note: At this time, while Firefox does implement read(), it does not recognize the "clipboard-read" permission, so attempting to use the Permissions API to manage access to the API will not work.


<img id="source" src="butterfly.jpg" alt="A butterfly">
<img id="destination">


img {
  height: 100px;
  width: 100px;
  margin: 0 1rem;
  border: 1px solid black;


const destinationImage = document.querySelector('#destination')
destinationImage.addEventListener('click', pasteImage);

async function pasteImage() {
  try {
    const permission = await navigator.permissions.query({ name: 'clipboard-read' });
    if (permission.state === 'denied') {
      throw new Error('Not allowed to read clipboard.');
    const clipboardContents = await;
    for (const item of clipboardContents) {
      if (!item.types.includes('image/png')) {
        throw new Error('Clipboard contains non-image data.');
      const blob = await item.getType('image/png');
      destinationImage.src = URL.createObjectURL(blob);
  catch (error) {
