When uploading an HTML5 file, please be sure to upload either:

  • A single HTML file with all assets linked as external URLs.

  • A zip. We look in the zip for an index.html file. If none is found we look for another file ending in .html, if no .html file is found the zip, nothing will be rendered. We only go 1000 check paths in the zip, so very nested HTML files might not be found.

With HTML5, you can toggle between mobile, desktop and standard view.

Maximum File Size

Oroson does not have a file size limit. We accept any file sizes that you upload to the platform.

We are constantly adding new file types and always keen to hear what you would like to see accepted on our platform.

How do files that are not supported appear on Oroson?

You can upload any file to Oroson, even if it doesn't appear on the list above. If you upload a file that is not supported, your reviewer will see that a file is there but no preview is available. Instead, they will be prompted to download the file for review.
