Kompressor - Compress images4.2

Kompressor (a compressor with a K!) is a powerful yet simple image converter for your iPhone and iPad. Convert your photos - RAW files from your iPhone or DSLR camera*, or standard lossy images already in your library - into compressed JPEG or HEIC formats while maintaining control over quality, size, and metadata.

REQUIREMENT: You need existing photos in your Photo Library to convert. Kompressor does not capture photos - it converts the image files you already have.

Support for both RAW and standard (JPEG, HEIC, PNG) input formats
Support for JPEG and HEIC output formats

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