Sorry，手殘打錯咗，係「HEIF」才對！
呢個HEIF檔咁啱我好早之前研究過，之前寫低咗研究結果，可以copy喺度畀你參考一下，睇吓得唔得
「
首先如果係手機，最好影相嗰陣唔好校用HEIF，校返做JPG去影，因為HEIF好麻煩，尤其是去到雲端有啲app認唔到HEIF，只係認到JPG、PNG嗰類，結果用HEIF就preview唔到張圖個樣
如果咁唔好彩之前校咗用HEIF去影，咁就最好轉檔轉返做JPG
至於轉檔都好有技巧，唔係隻隻都得，我之前試過一輪先試到隻最適合
例如我之前試過用HEIC File Converter 1.2.0 免安裝版，但係呢個唔得，因為JPG會變色，唔同原本張圖，後尾知道原因係因為唔可以resolution 100%，但呢個軟件冇得校，所以轉用iMazing Converter
用iMazing Converter嗰陣，Format要用JPEG（因為PNG啲色會唔同咗少少，而且file size變大咗好多），Quality要100%，Resolution 99.9%（因為100%會變灰少少，唔知點解），最後一係差唔多，一係顏色sharp啲靚咗
file size比原本HEIC多半倍左右

他說的是 HEIC, 不是HEIF
兩個有少許分別, HEIC 是 平果專用格式, HEIF 是通用性格式, 兩個格式好接近, 但仍有少許分別.
HEIC 與 HEIF 的分別可以參考這裡

OK 再研究下先
不懂，改后缀不行？

哦，我都沒有發覺，不過我在microsoft app store裏看到它的描述，它寫自己在version 2除了HEIC之外都可以support HEIF的，我估它在官網的描述未更新而已，它在microsoft app store的更新描述比較齊全一些，不過我就沒有試過，你可以試一試
