Ultimate Solution: How to Free Up Over 50GB Using HEVC Compression
50 GB is not an arbitrary number. It's roughly the size of the gap between a manageable iPhone and one that's constantly flashing storage warnings. It's the difference between the 50 GB and 200 GB iCloud tiers. It's enough space for 7,000 more photos or 5 more hours of 4K video.
And for most iPhone users with 80-200 GB of media, 50 GB is a realistic target through HEVC compression alone—no deleting, no cloud migration, no sacrificing a single memory.
This guide provides a concrete, step-by-step plan to identify where those 50 GB are hiding, compress them efficiently, and verify the results. If you follow the plan completely, you'll almost certainly exceed the 50 GB target.
Prerequisites: Who Can Realistically Hit 50 GB?
Not every iPhone has 50 GB to reclaim. Here's how to determine if you're a candidate:
Check your video storage: Settings > General > iPhone Storage > Photos. If Videos alone consume 60 GB or more, you're almost guaranteed to hit the 50 GB target.
Estimate your codec split. If you've owned iPhones since before 2017, received videos from Android users, or saved content from messaging apps, a significant portion of your library is likely in H.264. H.264 videos offer the largest compression gains (50-60% each).
Reality check by library size:
| Video Library Size | Estimated H.264 % | Realistic Savings | Can Hit 50 GB? |
|---|---|---|---|
| 30 GB | 60% | ~15 GB | No |
| 60 GB | 50% | ~28 GB | Unlikely |
| 80 GB | 40% | ~38 GB | With photos, yes |
| 100 GB | 50% | ~50 GB | Yes |
| 150 GB+ | Any | ~60-80 GB | Easily |
If your video library is under 60 GB, you can still reclaim significant space—just adjust the target to 20-30 GB.
Photos Count Too
Don't forget photos. A library of 10,000+ photos with ProRAW shots, Live Photos, and bursts can add another 5-15 GB of savings on top of video compression. Combined, videos + photos almost always exceed the 50 GB target for users with large libraries.
Phase 1: Assessment (10 Minutes)
Before compressing anything, get a clear picture of the opportunity.
Assess Your Library
Open Settings > General > iPhone Storage and note the total used by Photos (videos + photos combined)
Open HEVCut and run a full library scan — this takes 30-60 seconds and shows total potential savings
Note the scan results: how many H.264 videos, how many HEVC videos, estimated total savings for video and photos
If estimated savings are 40 GB+, you're on track. If they're 25-40 GB, adding photo compression will likely push you past 50 GB
Phase 2: Video Compression — The Big Win (2-4 Hours Unattended)
Video compression accounts for 70-85% of the total savings in this plan. This phase runs mostly unattended—queue it up and let it work.
Step 1: Start with H.264 videos
These offer the largest per-file savings. Converting H.264 to HEVC typically shrinks files by 50-60%.
What to select: All videos identified as H.264 by HEVCut. Common sources include:
- Videos recorded on iPhone 7 or earlier
- Videos received via WhatsApp, Telegram, or email
- Videos transferred from Android devices
- Screen recordings from older iOS versions
- Downloaded content
Profile to use: Balanced. This delivers the best savings-to-quality ratio for general content.
Step 2: Compress large HEVC videos
Even videos already in HEVC can be optimized. During recording, the iPhone uses higher bitrates than necessary for storage. Post-recording optimization typically saves 25-40%.
What to prioritize:
- 4K 60fps recordings (largest files, ~400 MB/min)
- Long continuous recordings (events, lectures, live streams)
- Drone footage at maximum bitrate settings
Profile to use: Balanced for most content. High Quality for footage you plan to edit.
Step 3: Queue and process overnight
Select all eligible videos, queue them for batch compression, plug your phone into power, and start processing. HEVCut continues in the background—you can use your phone normally or let it process while you sleep.
Expected processing time:
- 100 videos (~150 min total): ~2 hours
- 300 videos (~400 min total): ~5 hours
- 500+ videos: ~8 hours (overnight is ideal)
Pro Tip
Start the batch before bed. Most iPhone users have enough compressible video to keep the processor busy for 3-6 hours. By morning, your entire library will be compressed and ready for review.
Phase 3: Photo Compression — The Extra Push (30 Minutes)
After videos, compress photos to push past the 50 GB target or add buffer.
Highest-value photo targets:
| Photo Type | Per-Photo Savings | If You Have 500 | Total Savings |
|---|---|---|---|
| ProRAW (48 MP) | ~21 MB each | 500 | ~10.5 GB |
| Live Photos | ~4 MB each | 2,000 | ~8 GB |
| 48 MP HEIF | ~8 MB each | 1,000 | ~8 GB |
| Standard JPEG | ~2 MB each | 5,000 | ~10 GB |
Queue all eligible photos for compression. Photo processing is faster than video—a library of 5,000 photos typically completes in 15-20 minutes.
Phase 4: Cleanup — Actually Reclaiming the Space (5 Minutes)
Compression creates optimized copies. To actually reclaim space, you need to delete the originals.
Finalize Space Recovery
Review compressed results: spot-check 5-10 videos and photos across different types to verify quality
Delete all originals through HEVCut's built-in deletion flow (confirms which files to remove)
Open Photos > Albums > Recently Deleted and tap 'Delete All' — this is the step most people forget, and it can hold 10-20 GB
Go back to Settings > General > iPhone Storage and verify the new total — you should see a dramatic drop
Don't Skip Recently Deleted
Deleted files sit in Recently Deleted for 30 days, still consuming storage. After a major compression session, this folder can contain 20-50 GB of originals. Emptying it is where you actually see the space freed up. It's safe—the compressed versions are already in your library.
Phase 5: Prevention — Keeping the Space Free
Reclaiming 50 GB means nothing if it fills back up in three months. Set up these preventive measures:
Camera settings: Verify Settings > Camera > Formats is set to "High Efficiency." This ensures new recordings use HEVC automatically.
Monthly compression: Spend 10 minutes each month compressing new H.264 videos from messaging apps, downloads, and transfers.
Message cleanup: Set Settings > Messages > Keep Messages to "1 Year" to auto-delete old conversations and their massive media attachments.
App offloading: Enable Settings > App Store > Offload Unused Apps to automatically remove apps you haven't used recently.
Real Results: What Users Typically Achieve
Based on the typical iPhone usage patterns, here's what to expect:
Moderate Library (60-80 GB media)
- - Video compression: 20-35 GB saved
- - Photo compression: 5-10 GB saved
- - Recently Deleted cleanup: 3-8 GB
- - **Total: 28-53 GB reclaimed**
Large Library (120-200 GB media)
- - Video compression: 45-80 GB saved
- - Photo compression: 8-20 GB saved
- - Recently Deleted cleanup: 10-25 GB
- - **Total: 63-125 GB reclaimed**
The Financial Impact
Storage savings translate directly to money saved:
- iCloud tier reduction: If compression drops you from the 200 GB ($2.99/mo) to 50 GB ($0.99/mo) tier, you save $24/year
- Avoided upgrade: If compression eliminates the need to jump to 2 TB ($9.99/mo), you save $108/year
- No new phone needed: Some users upgrade phones primarily for more storage. Reclaiming 50 GB can delay that upgrade by a year or more
Over 3-5 years, the savings from avoiding iCloud upgrades and delaying phone purchases can easily reach $100-$500.
FAQ
What if I don't hit 50 GB?
If your library is smaller than expected, 30-40 GB is still a significant win. The strategies work regardless of the target—the 50 GB number is based on typical large-library users. Even 15-20 GB of savings can eliminate the storage warning permanently.
How long does the entire process take?
Active time: about 30 minutes (assessment, setup, review, cleanup). Unattended processing time: 2-8 hours depending on library size. The optimal approach is to do the active setup in the evening and let batch processing run overnight.
Will my phone be slow during compression?
No. Hardware HEVC encoding is handled by dedicated silicon, separate from the main CPU. Your phone remains fully responsive during compression. You can use any app normally while processing runs in the background.
What if I want to be extra cautious about quality?
Compress 10 videos first using the High Quality profile. Watch them on your TV or largest screen. If you can't spot any difference (you won't), proceed with the full batch at Balanced for better savings. You can always use High Quality for the footage you care most about.
Can I do this on an older iPhone?
Yes, on any iPhone from iPhone 8 (2017) onward. Older phones will process more slowly due to less powerful hardware encoders, but the results are identical. Expect processing to take roughly 2x longer on an iPhone 8-11 compared to iPhone 14-16.
Should I compress before or after backing up to iCloud?
Compress first. This way, the smaller compressed files are what sync to iCloud, reducing both your local storage and your cloud storage usage. If you compress after syncing, the originals in iCloud still take up space until iCloud syncs the changes.
