Tuji

Tuji is a macOS screenshot utility that lets users capture full‑screen, windowed, or custom‑area images, then edit them directly within the same application. It supports opening existing images from disk or the clipboard, and each capture is stored in a history panel for later reopening and modification.

The editing suite includes text, arrows, shapes, mosaics, watermarks, QR codes, and a magnifying glass, all with customizable colors and styles. Users can enhance screenshots with borders, shadows, gradients, wallpapers, or plain‑color backgrounds, and they can adjust the aspect ratio—such as 3:2 or 16:9—while filling empty space with the chosen background.

Export options are limited to a single click: the edited image can be copied to the clipboard or saved as a file, with configurable defaults for these actions. All processing occurs locally, and no personal data is transmitted or stored in the cloud.
