# Objective - Enable taking a screenshot in wasm - Followup on #7163 ## Solution - Create a blob from the image data, generate a url to that blob, add an `a` element to the document linking to that url, click on that element, then revoke the url - This will automatically trigger a download of the screenshot file in the browser
