i am using this jpeg recompressor:

https://github.com/danielgtaylor/jpeg-archive

Tried a lot of combinations of quality, and settled for -q medium --max 75% --accurate

Anything higher makes no sense/difference, even if you print it at A3. And my images are 8-18-24Mpix.

i'm not a pro-foto but somewhat of an old pre-print school - Your level of pickiness may vary :/

Effectively it is like 4-8 times down - Total went from 150Gb into 30Gb - that's about 40,000 images.

Which still doesn't solve the OP's or anyone's problem of too-easy-producible digital "assets".. but is more manageable.



I guess it depends on how much one values "archiving", but WebP has a lossless option [1] that might be a good alternative to the above.
