Kompressor – Compress images

【2026.04.01iOS限免】

Kompressor (a compressor with a K!) is a powerful yet simple RAW image converter for your iPhone and iPad. Convert your RAW photos, whether taken with your iPhone or DSLR camera*, into compressed JPEG or HEIC formats while maintaining control over quality, size, and metadata.

REQUIREMENT:
You need existing RAW photos in your Photo Library (from your iPhone or imported from a camera) to convert. Kompressor does not capture photos—it converts the RAW files you already have.

KEY FEATURES:
- Convert up to 25 RAW images at once
- Support for JPEG and HEIC output formats
- Adjustable compression levels (50%, 75%, 95%)
- Flexible image resizing options
- Complete control over metadata preservation
- Detailed metadata options including EXIF, GPS, TIFF, and more
- Device-specific metadata support (Apple, Canon, Nikon, Fuji, Olympus, Pentax, Minolta)
- Comprehensive compression statistics and charts
- Preview converted images before saving
- Clean, intuitive interface
- 100% offline processing - no data collection
- Support for iPhone and iPad

METADATA CONTROL:
Kompressor gives you granular control over which metadata to preserve:
- Image Depth & Orientation
- EXIF, GPS, and TIFF metadata
- IPTC information
- Camera manufacturer-specific data
- DNG metadata
- Custom creation date options

COMPRESSION OPTIONS:
Choose from three quality levels:
- 50% - Maximum compression for space savings
- 75% - Balanced quality and size
- 95% - Near-original quality with significant size reduction

RESIZING OPTIONS:
Reduce image dimensions while maintaining aspect ratio:
- 50% - Half the original size
- 75% - Three-quarters of original size
- 100% - Keep original dimensions

PRIVACY FIRST:
All processing happens directly on your device. No analytics, no tracking, no cloud processing. Your photos stay completely private.

PERFORMANCE:
Optimized for modern iOS devices with support for the latest iPhone and iPad models. The app limits batch conversions to 25 images to ensure optimal performance.

Perfect for photographers who want to:
- Free up storage space by converting RAW files
- Share photos in more compatible formats
- Control file sizes for uploads
- Manage photo metadata
- Convert images without complex desktop software
