JDeli is able to open and export images as HEIC files, giving a complete bulk HEIC converter between HEIC file format and lots of other image file formats.
JDeli can do this in ONE step with the convert method or separately open and export the HEIC image.
Batch Convert images to HEIC from Command Line or other language
java -jar jdeli.jar --convert heic "inputFileOrDir" "outputDir"
Convert into HEIC or from a HEIC image file in Java
JDeli.convert(File inFile, File outFile); JDeli.convert(InputStream inFile, OutputStream outfile, String format); byte outputData=JDeli.convert(byte inputData, String format);
An additional set of methods allow values to be passed in which can give more control over conversion, depending on the image formats being converted (ie different image compression options).
