You can upload any file, including images, texts, pdf, videos and so much more provided they are not harmful files such as computer viruses, pornography, or anything against our Terms of service.
Back-end or server side scripts are also forbidden (and will be disabled by default) so as to avoid possible server-side attacks and improve our security.
However, HTML website files and other "front-end" resources can be uploaded. This is done by uploading a single .zip file containing all the front-end website (file) resources within and make sure to include an index.html page.
