About HEIC

HEIC (HEVC-coded HEIF image)

HEVC-compressed images in a HEIF container. iPhones have saved photos this way by default since iOS 11 in 2017, at much smaller sizes than JPG, but Windows and many websites cannot open them without extra codecs. Convert HEIC to JPG or PNG to open iPhone photos on Windows, upload them to sites that reject HEIC, or share them.

About FITS

Flexible Image Transport System

The standard data format in astronomy since 1981, storing images and tables behind plain-text headers that record telescope and observation details. Convert from FITS to get a viewable PNG or JPG of telescope data; convert to it for astronomy software.
