iPhone
Storage full? Slim shrinks your photos & videos right on your iPhone. Keep Live Photos, date and location. Originals stay in Recently Deleted until you confirm.
Your iPhone says "Storage Almost Full." Slim fixes it in minutes — without deleting a single memory.
Slim compresses your photos and videos right on your device, cutting file sizes by 50–80% while keeping them looking great. The originals are safely moved to Recently Deleted, and gigabytes of space come back.
HOW IT WORKS
1. Pick an album (or your whole library)
2. Choose a quality tier — Safe, Smart, or Maximum
3. Watch the gigabytes come back. That's it.
WHY SLIM
• 100% on-device — photos and videos NEVER leave your phone
• No account, no sign-up, no cloud, no tracking
• Keeps dates, locations and metadata intact
• Compresses videos with modern HEVC — huge savings on 4K clips
• Finds similar & duplicate photos so you clear the clutter too
• Always starts with your newest, biggest files first
• See exactly how much space you'll get back — before you start
PRIVATE BY DESIGN
Slim has no servers. All processing happens on your iPhone using Apple's own frameworks. We can't see your photos — nobody can.
FREE TO TRY
Compress up to 1 GB of savings free. Upgrade to Slim Pro for unlimited compression:
• Lifetime — pay once, own forever (launch sale!)
• Annual or Monthly — flexible, cancel anytime
Slim never deletes anything silently: originals go to Recently Deleted through the standard iOS confirmation, recoverable for 30 days.
Free up your storage. Keep your memories.
