HEIF support #
Ver 3.4+: SumatraPDF can open HEIF images but only if Windows has a codec for the format.
You can use one of those codecs:
- https://www.copytrans.net/copytransheic/ : free for personal use
- https://www.microsoft.com/en-us/p/heif-image-extensions/9pmmsr1cgpwg?activetab=pivot:overviewtab : HEIF image codec from Microsoft, Windows 10 or later
You can make SumatraPDF to be default program for handling those file types.
