Tunacan
Tunacan is a macOS image layout app that combines multiple pictures into one neatly arranged image for screenshots, guides, and simple visual composites.
What is Tunacan?
Tunacan is a native macOS app for arranging multiple images into a single combined image. It is designed for people who need a quick way to line up screenshots, photos, or other graphics without using a full-featured editor. A common use case is creating long app tutorial images or stitched visual instructions where spacing and alignment need to look clean. Tunacan lets users import images, adjust margins between them, and automatically resize and place them into one finished layout. The app is lightweight and focused on this specific workflow rather than broader photo editing tasks. It is published under the Kreuz45 name and distributed for Mac through the Mac App Store.

Safety overview
Status: Mostly safe
Tunacan is a legitimate Mac App Store application for image composition, and its expected file access is consistent with selecting and exporting images. The main point to check is naming: the bundle ID uses com.kreuz45.tunacan2, so users should confirm it is the Tunacan app they installed before removing related files. No unusual background behavior is associated with its normal purpose.
Recommendation: Keep Tunacan if you use it to combine screenshots or images into a single layout. If you no longer need that workflow, you can remove the app and its related support files; doing so may delete saved settings or app data tied to Tunacan.
