How Photo Compression Works
Simple process, significant savings
1. Scans Your Library
HEVCut automatically finds photos in your library that can be compressed to save space. It calculates the potential savings for each photo before you commit.
2. Smart Compression
Advanced algorithms analyze each photo and apply optimal compression. The process removes invisible data while maintaining visual quality that's indistinguishable from the original.
3. Save Storage
Reclaim gigabytes of space on your iPhone and iCloud instantly. The compressed photos replace the originals, so you see the storage savings immediately.
Why Are Your Photos So Large?
Understanding why modern iPhone photos consume so much storage
Modern iPhones capture photos at extremely high resolutions. The iPhone 15 Pro shoots 48-megapixel photos in ProRAW format that can be 50-75MB each. Even standard photos at 12 megapixels are typically 3-5MB. Over thousands of photos, this adds up to tens or hundreds of gigabytes.
Much of this file size is redundant data. Photos contain more detail than your eyes can perceive, especially in solid color areas like sky or walls. Compression algorithms can remove this invisible information without any perceptible quality loss. A 5MB photo can often be reduced to 1-2MB while looking identical.
HEVCut uses intelligent compression that adapts to each photo's content. Photos with lots of fine detail (like landscapes with many textures) are compressed more conservatively. Photos with large smooth areas (like portraits or product shots) can be compressed more aggressively without any visible difference.
Typical Compression Results
Savings of 50-70% are typical. The exact compression depends on photo content.
Quality You Can't Tell Apart
Smart compression preserves what matters
Visually Identical
HEVCut uses perceptual compression that removes only data your eyes can't see. When you compare the original and compressed photos side by side, you won't be able to tell them apart—even when zooming in.
Detail Preserved
Fine details like text, faces, and textures are preserved at full quality. The compression focuses on areas where quality loss is imperceptible, like gradients and solid colors.
Metadata Intact
All your photo metadata is preserved: date taken, location, camera settings, and more. Your photos stay organized in albums and the Memories feature continues to work normally.
Adjustable Quality
Choose your compression level. Higher compression saves more space but may show slight quality loss on close inspection. The default setting is a balance that's indistinguishable for most uses.
Works With All Your Photos
Comprehensive format support
Apple's HEIC
The default format for iPhone photos since iOS 11. Already efficient, but HEVCut can often reduce file size by another 30-50%.
Standard JPEG
Older photos imported from other devices or downloaded from the web. These often have the most room for compression improvements.
PNG Images
Screenshots and graphics saved as PNG. These are often much larger than necessary and compress well, especially if converted to HEIC.
Common Questions
QDoes it delete my original photos?
You have full control. You can choose to replace the originals with the optimized versions or keep both. Replacing them saves the most space. The original is moved to Recently Deleted for 30 days before permanent removal.
QWill my photos look blurry?
No. HEVCut uses smart compression technology that reduces file size by removing invisible data, keeping your photos looking sharp and clear. At normal viewing sizes and on screens, you won't notice any difference. Only extreme zooming on a high-resolution display might reveal subtle differences.
QDoes it work with iCloud?
Yes! HEVCut works seamlessly with your iCloud Photo Library. When you compress a photo, the smaller version syncs to iCloud, and you save space across all your devices. If you're running low on iCloud storage, compressing photos is often the most effective way to free up space.
QCan I print compressed photos?
Yes, compressed photos are still high-quality and suitable for printing. Even after compression, your photos retain enough resolution for large prints. For professional or large-format prints, you may want to keep the original files.
QHow much space can I save?
It depends on your photo library size and the types of photos you have. Most users save 30-50% of their photo storage. If you have 20GB of photos, you could free up 6-10GB. Users with lots of ProRAW photos or older JPEGs often see even greater savings.
