First of all awesome implementation, i had a lot of trouble where when i converted from heic to jpg/jpeg it just removed that underlying metadata (including the exif data).

However in your convert module you specify that this following logic rotates the image upright, but through different test it does not seem to do it. And i usually deal with quite a lot of heic images that are rotated differently, and we want to store the image in it's "correct orientation"
// Conversion rotates the image upright if (ifd0[piexif.TagValues.ImageIFD.Orientation] > 4) { const xd = exif[piexif.TagValues.ExifIFD.PixelXDimension] const yd = exif[piexif.TagValues.ExifIFD.PixelYDimension] exif[piexif.TagValues.ExifIFD.PixelXDimension] = yd exif[piexif.TagValues.ExifIFD.PixelYDimension] = xd ifd0[piexif.TagValues.ImageIFD.Orientation] = 1 }

This is my implementation:

if (fileExtension === "heic") { const outBuffer = await convert(file.buffer, undefined, 0.7); fileObj = { originalname: file.originalname, buffer: outBuffer, }; }

Thank you very much
