Why convert HEIC to PDF?
HEIC is the default photo format on iPhone and iPad. It keeps good quality at about half the size of JPG, but Windows, many websites and upload forms do not accept it.
PDF is the format forms, schools, employers and portals expect. One tidy document is also easier to send and print than a folder of images.
