Kompressor - Compress images
RAW Image Converter
Free
Convert RAW images to JPEG or HEIC with full control over compression, size, and metadata. Perfect for photographers who want to save space without sacrificing quality!
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.

RESIZING OPTIONS:
Reduce image dimensions while maintaining aspect ratio:
- 50% - Half the 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.
