Run on an already existing library?

[zolakt]

Hi,

could this be ran on photos already imported to Immich library?

If not, does anyone have a suggestion on how to safely, manually, compress files, without breaking Immich's db

That would be a good feature but I don't have time to make it, I don't need it.

It's easy to implement, you just get all assets from the immich server using the API, download them, convert and then use the replace asset API. Either edit my code or make a bash script to do it automatically. Otherwise you'll have to do it manually one by one, on the web ui there are download and replace with asset buttons, not feasible for many assets.

The best way would be to update the immich db directly, it's harder to do but should be faster cause it would avoid unnecessary thumbnails re-generation (replace API is basically the same as a new upload except the asset id is kept, everything else is lost and needs to be computed again, AI stuff too if you have it enabled)

you also need to keep hashes of the original and converted file and add them to checksums.csv if you don't want to see duplicates in the mobile app (unless you deleted the files from your phone)

Thanks for the reply. If the replace API is the same as new upload, except the assets id is kept, then it's definetly a no go. I have thousands of images, and spent days on properly tagging people, deleting people I'll never need, setting locations, descriptions etc... It would be suicide to go through all of that again. Basically, that would be identical as starting from scratch...

I guess I'll have to make some script that updates the db, if I ever get the time to do it.

it's not identical, you will still have albums and all the things using the asset id, locations, descriptions, etc are all linked to the asset id. I don't think people are, cause if the image is different it would be wrong, try one image, see what happens

Aha, ok, I'll give it a try. I think people are linked as well. I know I deleted stuff from the asset_faces table to get rid of the soft-deleted faces that I will never need. It's just question if the replace API explicitly deletes those or not. Although, my guess is it doesn't, since nothing else I tried fully deletes those. When you remove it through the UI, it just gets soft-deleted, so I guess (if they are consistent), this should do the same.
