What is kompressor.app?
Kompressor is a native macOS image converter that handles over 50 input formats and more than 20 output formats. The range covers common formats such as JPEG and PNG through to Camera RAW files, HEIC, AVIF and Photoshop files. The app runs entirely offline, sends no data to the cloud and has no tracking. It is developed and maintained by a single developer as a side project.
Core features
- Broad format support: Over 50 input formats including Camera RAW and less common formats such as AVIF and HEIC, plus more than 20 output formats including WebP and JPEG.
- Batch processing: Convert and resize multiple images at once. Useful for high-volume file workflows, for example in e-commerce.
- EXIF data management: Metadata such as GPS coordinates and device information can be selectively removed before images are shared.
- Drag-and-drop with real-time preview: Drop files directly into the window and review the result before exporting.
- Apple Silicon optimised: The app is built for the architecture of modern Macs and targets M-chip devices.
Who is kompressor.app for?
Photographers preparing RAW files for web publication benefit from a direct path from camera raw data to JPEG or WebP without routing through Lightroom or Photoshop. Designers and content teams who regularly process large sets of images for online shops or websites can put the batch function to productive use. Anyone sharing photos that carry sensitive metadata has a practical privacy tool in the EXIF cleaning feature. A Mac is required. Windows and Linux users are ruled out entirely.
Context & alternatives
Kompressor fills a clearly defined niche: a native Mac converter with no subscription, no cloud and a guaranteed offline workflow. Comparable tools on macOS include Permute, or command-line tools such as ImageMagick and libvips, both of which require considerably more setup. Online converters are not an option when privacy or a reliable offline environment is a requirement. For anyone looking for a lightweight desktop tool for Mac who does not want to run a subscription service, Kompressor is a solid choice. The update cadence of a solo project does mean that new formats and bug fixes can take longer to arrive.
