Frequently asked questions
Does the preview execute embedded HTML scripts?+
No. The isolated preview disables scripts and removes active content. The HTML source export retains authored raw HTML, so review it before publishing elsewhere.
Are my files uploaded?+
No. Processing happens on this device. The tool may download its own code, but source files and output are not sent to a processing server.
