File Size Estimator
Estimates total size for a batch of photos from dimensions, format and quality, then tells you how long it will take to upload at your connection speed.
85 — 85 is the usual delivery setting; above 95 costs a lot of size for very little.
Your upload figure, not download — they're rarely the same.

These are estimates from real-world bits-per-pixel averages, not a simulation of your encoder. Expect to land within about 20% either way — noise and fine texture push it up, flat studio backgrounds pull it down.
