Used to convert HEIC/HEIF photos to JPEG inside your browser so they can be
previewed in browsers without native HEIC support. It runs entirely on your
device; no image data is sent anywhere.

heic-to is used unmodified. It is loaded as a separate JavaScript file, only
when a HEIC preview needs it, and is not combined into ShieldFive's own code.
You may replace it with a modified version of the library. The corresponding
source code is available at the links above, and on request from
support@shieldfive.com.
