The PHB Brother ULT Embroidery Format is a proprietary embroidery file format created by Brother. It is used to store embroidery designs for Brother embroidery machines, and can be read by Brother's embroidery software. The PHB file format is not compatible with other embroidery software.
It is an image compression codec file with the same quality as .jpeg, but that is ten smaller. It supports HDR (High Dynamic Range). SDR (Standard Dynamic Range), and WCG (Wide Color Gamut) images. Also, it contains both the image sequences and image items. The only pitfall is that a few applications support it.
