I understood, that I have to export them and cannot just "save" them. I made a standard batch JPEG full size and the size of the photos shrank noticeably. Then I tried a new batch with JPEG and 100% quality. This time the size went enormously up.
What did I do wrong? Which batch should I use, not to loose quality and without expanding the storage? (so the size is equal withe the original photos)
