Is Clipboard2File (Upload From Clipboard) safe?

Clean risk

Clipboard2File reads clipboard images or text after file-input clicks and prepares them as files for upload.

When you click a file upload field, Clipboard2File checks the clipboard for an image or, if enabled, plain text. It shows a preview and only assigns the clipboard content to the website's file input after you click the extension preview button.
