- Download the compressed HEIC photos, or grab all as a ZIP.
Quick fact about HEIC
iPhone photos are usually 2-4 MB HEIC files. Compressing to 80% quality reduces size by 50-70% with no visible difference on phone screens — perfect for freeing storage or sharing.
Why compress HEIC?
iPhone photos are saved as HEIC (Apple's efficient format), but each photo is still 2-4 MB. Compressing to 80% quality reduces size by 50-70% with no visible difference on phone screens — perfect for freeing iPhone storage, sharing via WhatsApp, or meeting upload caps on forms.
Technical details
| Input format | HEIC, HEIF |
| Output format | HEIC |
| Codec | HEVC (H.265) |
| Quality range | 60-90% |
| Typical reduction | 40-70% at 80% quality |
| EXIF metadata | Preserved |
| Max file size | 50 MB per file |
| File retention | Auto-deleted after compression |
How the conversion works
The compressor decodes the HEIC image and re-encodes it at a lower quality setting using libheif. The output is a smaller HEIC that plays natively on iPhone, iPad, and Mac. Metadata and EXIF orientation are preserved.
When to compress HEIC
- Sharing iPhone photos via WhatsApp with size limits.
- Freeing iPhone storage by compressing old photos.
- Preparing iPhone photos for email attachments.
- Meeting upload size limits on web forms.
- Reducing iCloud storage usage.
- Preparing iPhone photos for archival.
- Batch-reducing an iPhone photo library.
Quality considerations
HEIC at 80% quality is visually indistinguishable from 100% on phone and laptop screens. Below 70% quality, artifacts start showing in detailed areas. HEIC's HEVC compression is very efficient, so quality 80% still looks great.
Limitations and caveats
- HEIC files are already compressed by the iPhone camera — savings are 40-70%.
- Some sharing platforms require JPG (convert first).
- Animated HEIC sequences use the first frame only.
- HDR metadata may be lost at lower quality settings.
- Below 70% quality, visible artifacts may appear.
Compatibility
- Compressed HEIC opens natively on iOS 11+, iPadOS, macOS.
- Windows 10/11 supports HEIC with the free HEIF Image Extensions.
- Native support in Photos, Preview, and Adobe CC.
- Syncs with iCloud Photos.
- Ideal for Apple-centric photo libraries.
Tips for best results
- 80% quality is the sweet spot — 40-60% smaller, no visible change.
- For WhatsApp, use 70% quality or the target-size preset.
- Batch-compress up to 50 MB of HEIC files at once.
- Keep the original if the photo is irreplaceable.
- For non-Apple platforms, convert to JPG first.
Compression levels explained
| Level | Size reduction | Best for |
|---|---|---|
| Low (90% quality) | ~20-30% | Archival |
| Medium (80% quality) | ~40-60% | Sharing, social media |
| High (70% quality) | ~60-70% | WhatsApp, email |
| Maximum (60% quality) | ~65-75% | Strict size limits |
Common problems and fixes
- Compressed HEIC won't open on Android
- HEIC requires third-party apps on Android. Convert to JPG for cross-platform sharing.
- HDR data is lost
- Lower quality settings may lose HDR metadata. Use 'Low' (90% quality) for HDR preservation.
- Photo looks slightly soft at 60%
- Use a higher quality level (70-80%) for photos with fine detail.
