⚡ CalcWolf Insight

Google Photos compression (Storage Saver) reduces photo file sizes by ~75% with minimal visible quality loss. A 5,000-photo library that would use 25 GB in original quality uses only ~6 GB with Storage Saver — potentially keeping you within the free 15 GB tier. Enable it in Google Photos settings if storage is tight.
