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.
See duplicates grouped together, junk photos categorized, and large videos sorted by size. You're always in control of what gets cleaned.
Select what to remove and tap Clean. All deleted items go to Recently Deleted for 30 days — you can recover any mistakes.
Most users recover 5-15GB instantly. That's room for thousands more photos, dozens of apps, or just a faster iPhone.
Fast Cleaner is built for iPhone storage cleanup, with AI-assisted tools for duplicate photos, similar images, junk screenshots, and video compression. You can review cleanup suggestions before deleting, and core cleanup flows are designed to run on-device for privacy.
The fastest way to free iPhone storage: 1) Delete duplicate and similar photos (saves 2-8GB), 2) Compress large videos (saves 5-15GB), 3) Remove screenshots and junk images (saves 1-3GB), 4) Clear Safari cache. Use Fast Cleaner to automate all of these in just a few minutes.
iPhone storage fills up from: Photos and videos (usually 40-60%), Apps and app caches, System Data (caches, logs, temp files), Messages with attachments, and downloaded music/podcasts. Go to Settings > General > iPhone Storage to see exactly what's using space on your device.
Most users recover 5-15GB with Fast Cleaner on their first cleanup. Heavy users with large photo libraries often free up 20GB or more. Duplicate photos, similar shots, uncompressed videos, and forgotten screenshots typically waste 20-40% of your photo storage.
Fast Cleaner is designed to keep you in control. Core cleanup analysis happens on your device, and selected photos go to Recently Deleted for 30 days, so you can recover anything you deleted by mistake.
Yes, fully compatible. Fast Cleaner works whether you use iCloud Photos or not. When you delete duplicates with iCloud Photos enabled, they're removed from all your devices (syncing works normally). The app can detect duplicates even in optimized photo libraries.
