Convert xpm to heic
A browser can't do this one — here is what it can do.
Desktop app only
Nothing that runs in a tab can write heic from xpm. This pair is waiting on the desktop build, which hands the job to the real command-line tools.

X PixMap
The color successor to XBM, storing an image as a C array of strings with a text color table. Early Linux and Unix desktops used it for icons. Use it for X11 programs and older Linux desktops that expect XPM icons.
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.
