iPhone-Fotospeicher voll? 10 Wege, um Speicher freizugeben

A “Storage Almost Full” notification is iPhone users’ worst nightmare, especially when it threatens your photo library. The average iPhone user has 2,000-5,000 photos taking up 20-50 GB. Here’s how to reclaim that space.

Strategy 1: Switch from JPEG to HEIC

If your iPhone is set to “Most Compatible” (JPEG), switch to “High Efficiency” (HEIC):

1. Settings → Camera → Formats
2. Select High Efficiency
3. Future photos will be half the size

Existing JPEGs won’t shrink, but this prevents future storage problems.

Strategy 2: Convert HEIC Archives to Compressed JPEG

If you have thousands of HEIC photos you want to archive offline, batch-convert them at 80% quality:

1. Transfer HEIC files to your computer
2. Use heicgo.com to batch convert
3. Choose 80% quality — visually similar but files are ~60% smaller than original HEIC
4. Download the ZIP and store on an external drive

This frees up iCloud space while keeping acceptable-quality backups.

Strategy 3: Optimize iPhone Storage (iCloud)

Settings → Photos → Optimize iPhone Storage

This keeps full-resolution photos in iCloud and device-optimized versions on your phone. A 50 GB library may only use 2-3 GB locally.

Strategy 4: Delete Duplicate Photos

iOS doesn’t have a built-in duplicate finder, but:

• iOS 16+ has a “Duplicates” album in Photos → Albums → Utilities
• Third-party apps like Gemini Photos can find similar shots

Strategies 5-10 (Quick Wins)

5. Delete burst photos — each burst can be 20+ nearly identical shots
6. Clear Recently Deleted — photos sit there for 30 days, still using space
7. Remove downloaded media — check Settings → General → iPhone Storage → Review Downloaded Media
8. Delete old screenshots — search “Screenshot” in Photos, delete what you don’t need
9. Offload unused apps — they keep documents but free app binary space
10. Use HEIC for everything — Settings → Camera → Formats → High Efficiency

The Nuclear Option: Offline Archive

1. Transfer ALL photos to a computer
2. Batch convert HEIC to JPEG at 80% quality using heicgo
3. Store on an external SSD (1 TB costs ~$60)
4. Delete from iPhone and iCloud
5. Keep only the last 6 months on your phone

You’ll recover 30-100+ GB depending on your library size, have a permanent offline backup, and keep recent photos accessible.
