"Storage Almost Full." It's a notification we all face eventually while using an iPhone. Every time we want to install a new app or update the operating system, we habitually open our photo gallery and pick out our least important memories to delete. 'Disk Rescue' started from this everyday dilemma. It's a shame to have to erase past memories just to make room for new ones. This app converts your photos and videos into the most efficient, modern formats (HEIC/HEVC) without degrading their visual quality. To your eyes, the photos look exactly the same, but the weight your iPhone feels becomes nearly half as light. [How Disk Rescue helps you] Preserves as it is: Not only regular photos but also 'Live Photos' capturing the movement of precious moments are converted retaining their vividness, without being ruined into still images. Shows results in advance: Before you press the convert button, it intuitively shows you how much free space you will regain through this action. Safe and private: The entire conversion process is handled exclusively within your iPhone device. No internet connection is required, and your private photos are never sent to external servers. If the monthly cost of cloud storage is starting to feel burdensome, or if backing up has become overwhelming due to too many photos of children and pets, Disk Rescue can be a small help. Stop spending time choosing which photos to delete. Reduce the weight of your memories and expand the free space on your iPhone.
