The smartest way to clean iPhone storage. AI finds duplicates, compresses videos, and removes junk — freeing 5-15GB in minutes.
Three powerful tools that tackle the biggest storage wasters:
AI finds exact duplicates AND similar photos — burst shots, multiple angles, nearly-identical images that iPhone's built-in feature misses.
Typically saves 2-8GBReduce video file sizes by 50-80% with virtually no quality loss. 4K videos are the biggest storage hogs — compression is a game-changer.
Typically saves 5-15GBAuto-detect screenshots, blurry photos, web images, and other junk. Review and bulk delete in seconds instead of scrolling through thousands.
Typically saves 1-3GBUnderstanding what's consuming your storage is the first step. Here are the usual culprits:
By far the biggest storage consumer. Duplicates, similar shots, 4K videos, and screenshots pile up faster than you realize.
Apps accumulate caches over time. TikTok, Instagram, Spotify, and games can grow to gigabytes of cached data.
Safari cache, Siri voices, logs, and temporary files. This mysterious category can grow to 10-20GB on older iPhones.
Years of text messages with photos, videos, and attachments add up. A single conversation can contain gigabytes of media.
Fast Cleaner makes the cleanup process simple:
Open Fast Cleaner and let the AI analyze your photos and videos. The scan takes 1-3 minutes and shows exactly what's wasting space.

Select what to remove and tap Clean. All deleted items go to Recently Deleted for 30 days — you can recover any mistakes.
