Private Files in Digital Signage

Private Files

Private Files are for those who have confidential files in their content. With Private Files you avoid your files being transported over the Internet.

Normally when a file is uploaded directly or added via the “Public URL” option, it will be processed by our server and stored on the Internet, so that your browser and the player device can load it as long as there is an Internet connection. Our server obfuscates the file URL and makes it virtually impossible to guess in an attempt to hide it from others, but sometimes this can go against a company policy. If your organization stores files in a private file server, you can use these files without uploading them to our servers and thus expose them to the Internet.

You can add a private file by going to the library, clicking the “From URL” button, and selecting the “Private file” tab.

Key differences

  • Files will never leave your premises.
  • You can use large files without restrictions (our server has a 2 GB upload limit).
  • Supports following formats: .gif, .jpg, .jpeg, .png, .webp, .mp4, .m4v (other file types, such as .pdf, .mov or .doc require conversion in our servers).
  • Our support team can not help you if we can’t load the files.
  • Files are not processed by our server, therefore they are also not optimized for player devices (make sure not to use enormous files).
  • You can only use the editor and players while you are connected to the private network where the files are.


  • The files must be served over the HTTP protocol
  • The file server must enable CORS requests (Must return header Access-Control-Allow-Origin with value *).
  • If you plan on using files greater than 25 MB with our Chrome extension player, the server must also expose the Content-Range header (Access-Control-Expose-Headers with value Content-Range)
