Loading and editing HEIC/HEIF images
We can use the preprocessImageFile
property on the createDefaultImageReader
function to add custom image loader logic.
Using a third-party library called heic2any we can add HEIC image support to the editor.

FilePond
If you want to load HEIC with FilePond you have to set the imageEditorSupportImageFormat
property.
FilePond.create(document.querySelector('input'), {
// tell FilePond to support all images that have types starting with `image`
imageEditorSupportImageFormat: (file) => {
return (file) => /^image/.test(file.type);
},
// the image editor config
imageEditor: {
createEditor: openDefaultEditor,
imageReader: [
createDefaultImageReader,
{
// Converting the HEIC file to a JPEG
preprocessImageFile: async (file, options, onprogress) => {
// If is HEIC, we preprocess to a readable image format
if (/heic/.test(file.type)) {
// let's turn HEIC into JPEG so the browser can read it
const blob = await heic2any({
blob: file,
toType: 'image/jpeg',
quality: 0.94,
});
// Pintura Image Editor expects a File
return blobToFile(blob, file.name);
}
// no need to preproces
return file;
},
},
],
imageWriter: [createDefaultImageWriter],
imageProcessor: processDefaultImage,
editorOptions: {},
},
});
