• Så konventera du HEIF bilder till Jpeg.

    heif-convert är ett kommandoradsverktyg för att konvertera HEIF-bilder (High Efficiency Image Format), särskilt de som skapas av nyare iPhone-modeller, till mer allmänt accepterade bildformat som JPEG. HEIF ger överlägsen kompression jämfört med JPEG, vilket resulterar i mindre filstorlekar vid samma eller bättre bildkvalitet.

    Här är en enkel guide för hur man använder heif-convert:

    Installation:

    Innan du använder heif-convert, behöver du installera det. På många Linux-distributioner kan detta göras via pakethanteraren. Till exempel, på Ubuntu eller Debian:

    sudo apt install libheif-examples

    Grundläggande användning:

    1. Konvertera en HEIF-bild till JPEG:
       heif-convert input.heic output.jpg

    Här representerar input.heic din källfil i HEIF-format, och output.jpg är namnet på den JPEG-fil som ska skapas.

    1. Ändra kvalitet på utdata JPEG: Med standardinställningar kan kvaliteten på den resulterande JPEG-filen vara mycket hög. Du kan ändra kvaliteten genom att använda -q alternativet:
       heif-convert -q 80 input.heic output.jpg

    Här har vi ställt in kvaliteten till 80 (på en skala från 0 till 100).

    Andra parametrar:

    • heif-convert har några ytterligare alternativ och parametrar för att ändra konverteringsbeteendet. Du kan visa dessa alternativ genom att köra:
       heif-convert --help

    Det bör noteras att medan heif-convert är ett användbart verktyg för grundläggande HEIF till JPEG-konvertering, om du behöver utföra mer komplexa bildmanipulationer eller konvertera till andra format, kan andra verktyg eller programvaror vara mer lämpliga.
