Notes about the PHF file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The PHF file type is primarily associated with 'Photofont' by Fontlab Ltd.. Think of a Photofont as a collection of bitmap (PNG) images that use RGB color, loss-less compression, alpha transparency, and an XML attached tag. This collection works like a font, so you can press a key and get a certain image from the collection. You can create a Photofont with a text editor and a graphics program capable of exporting PNG files.
