EXIF data

[williamg97]

Any way to copy the EXIF data across (date taken, GPS location etc)?

I’d like to, and I’ve looked into this before. You might expect there is a simple way, but it seemed to me at the time that WIC did not make this easy. Instead, it seemed that the code would need to extract values individually by multiple names/aliases and possibly convert them along the way. I’ve done something similar on a previous project and it was quite messy. If I can find an efficient way to do this here, I will add it.

Exiftool supports r/w for both heic/heif and jpg.

@JohnStefanko Good find. It's simple enough (though inefficient and kludgy) to add a call to exiftool post-conversion. I'm dealing with this due to iOS storing images as HEIC, and using OneDrive for cloud storage. On my Windows systems, working with HEIC is terrible (e.g. the Windows Photos app refuses to save changes to images, like rotation or crop, even with MS's HEIF/HEIC add-on). I'm using this script and exiftool to find all HEIC files, convert them to jpeg, apply the EXIF metadata, and delete the original. Unfortunately I found the iOS setting to store as jpeg months after many images were taken. What a pain!

I wish I would have know that this issue existed before I modified my workflow. Thankfully, I found the same setting you referred to in the iPhone.

For anyone else reading this, I know the free CopyTrans program will convert AND retain EXIF data. Unfortunately, I haven't found a way to automate that conversion process so back to JPG I go.
