Kompressor - Compress images

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.
