Hi! If your image quantity is low you could disable automatic compression on new uploads. Then you could manually compress the images you like in the media library.
Alternatively if it’s just one image (your logo) then you could let it get compressed and then replace the resulting image on the file server with the original copy (because the compression entry is in the database it won’t be compressed again). Though that’s of course a bit of a workaround.
We’ll add being able to exclude certain images from being compressed as a possible feature to our list. If there’s more interest for it we’ll consider implementing it for a future update.
