HEIC file signature

问题

I'm looking for a comprehensive list of file signature for extensions. In particular, I have some trouble to find the file signature for the extension .HEIC (and .HEIF). Do you know where is it possible to get it?

You can use a hexadecimal file viewer in any OS.

For a comprehensive list of file signatures, please check https://www.filesignatures.net/

To check yourself using Windows, open a PowerShell prompt and type the following command for your file (https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/format-hex?view=powershell-7.1):

PS> format-hex c:\my.heic
