@atpfm @siracusa for me the biggest reason not to switch my Photos library to JPEG XL is right out of the previous chapter! They’re all copied into the library from the same disk, so I’d actually need more space afterwards since it would break the references!
@fifthrocket Sounds like you need my app…
@siracusa Wait, wouldn't the new JPEG XL files post-conversion contain different bytes than their source JPEG files?
@fifthrocket Yes, on disk, but they decompress to the exact same pixels.
