If files would be bit identical the corrupt one wouldn't be corrupt. Rather than ignore EXIF, EXIF might be just the thing you actually want to compare. In my experience with visually corrupt JPEGs, the 'header' and EXIF marker is often intact. | |

| Jun 14, 2020 at 21:45 | comment | added | gio91ber | I’ve already used different hashing methods with multiple programs to delete the “obvious” duplicates, yet I still don’t know how to pair the first pixels of a damaged jpg to its not damaged duplicate. I’ve actually just discovered AllDup has a bit-by-bit comparison mode with also an option to ignore jpg/cr2 metadata, but over 28000 pics it only found 8 duplicates, which is not credible at all. | |

| Jun 14, 2020 at 20:20 | comment | added | twalberg | This is a good first step, as it will help eliminate truly duplicate files. It will not find images that might have been (however slightly) modified from the original - even just re-encoding an image will usually create a different file with a different hash. Beyond that, there are some comparison utilities out there, like in ImageMagick (or its GraphicsMagick fork) | |
