CoolCroco

CoolCroco is a commercial Linux application in the Video & Media Players category. It is intended for photographers who need to review and cull a folder of images after a shoot. The application decodes the folder into RAM, allowing movement through many RAW files forwards or backwards after the initial pass without decoding each image again.

CoolCroco reads major camera RAW formats through LibRaw, including files from Sony, Canon, Nikon, Fujifilm, Olympus, Panasonic, Pentax, and Leica cameras. It also supports HEIC and HEIF images from an iPhone, along with JPEG, PNG, TIFF, and WebP. Culling uses keyboard controls: A moves a photograph to Approved, X moves it to Rejected, and Ctrl+Z restores it without deleting the original file. Ratings from one to five can be written in a form recognized by Lightroom, Bridge, and Capture One. A contact-sheet grid and a resizable thumbnail filmstrip provide different ways to move through the folder.

The application can search by image content using terms such as motorcycle or stars over a lake, with processing performed on the local computer after a one-time model download. It does not use face recognition, and the provided product information states that it will not add that capability. CoolCroco can identify near-duplicates, bursts, and timelapses, and it provides focus and camera-shake detection for soft-frame triage. Sticky zoom keeps the same image area selected across frames, while zooming decodes the image at full resolution for 1:1 inspection. EXIF data is shown in properties, selective EXIF removal can include a restorable backup, and IPTC data can be written either inside the file or as a sidecar.

As a Linux product, CoolCroco fits the catalog's Video & Media Players category by concentrating on image viewing, inspection, and media-file organization. MirrorNest does not mirror the application files and instead links directly to the official release. Photographs on an SD card or external drive require removable-media permission, which must be enabled in App Center or with the command snap connect coolcroco:removable-media.
