ICS at a glance
ICS
Convert to ICS when the output needs to be imported into calendar software, sent as an invite, published as a subscribable event feed, or exchanged between scheduling systems.
It is ideal for appointments, event series, meeting notices, and automated calendar workflows.
Use it when time and recurrence semantics matter more than generic document presentation.
KMZ at a glance
KMZ
Convert to KMZ when a KML-based map needs embedded images, icons, or overlays to move together as one deliverable.
It is the right target for portable Google Earth projects, offline map bundles, and shareable geospatial packages that recipients should be able to open without relinking external resources.
