What is HEIF format and does it reduce photo quality?

HEIF (High Efficiency Image File Format) is the modern replacement for JPEG. It uses smarter compression to produce files roughly half the size at the same visual quality. You won't notice a difference looking at the photos — but your storage number will drop significantly over time.

Does iCloud Optimize Storage delete photos from my iPhone?

It doesn't delete them — it replaces them on your device with smaller previews while keeping the full-resolution originals in iCloud. When you open a photo, the original downloads automatically if you have internet access.

Why are my photos still taking up so much space after changing the format setting?

The format change only applies to photos you take from now on. Everything already in your library stays in JPEG until you delete it. To tackle the existing backlog, use EverClean AI to find near-duplicates and large files.

Are Live Photos worth keeping enabled?

For moments you actually want to relive — yes. For the average snapshot of a receipt, a whiteboard, or a parking space — no. Disabling Live Photos by default and enabling it only when you want it is a practical middle ground that saves meaningful space over time.

How much storage can I realistically recover?

Switching to HEIF cuts ongoing storage growth by roughly 40–50%. A one-time scan with EverClean AI to remove near-duplicates typically recovers an additional 3–8 GB for people who've never cleaned up their library.
