HEIC photos
heic-to 1.6.5 turns HEIC photos into JPEGs in browsers that can’t read them. It contains libheif 1.23.5 and libde265, © struktur AG. All three are under the GNU Lesser General Public License, version 3 — the licence, the GNU General Public License it builds on and our notice.
It’s used unmodified, as its own file (/heic-to/heic-to.js), loaded only when someone adds a HEIC photo. Any compatible build of the same library can stand in for it there. Source: heic-to, libheif and libde265.
