Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

Tensaku is an open-source screenshot annotation desktop application for Linux Wayland environments. It is aimed at users who need more control than a flat markup tool provides, particularly those working with compositors such as Sway, Hyprland, River, or Wayfire. The editor supports arrows, shapes, text, highlights, blur, redaction marks, cropping, rotation, flipping, zoom, and measurement tools. Screenshots can be saved or copied to the Wayland clipboard.

Its strongest area is layered editing. Annotations can be moved, resized, and selected together, while the layer panel provides reorder, lock, hide, and rename controls. Images can also be pasted as resizable layers, which supports composite screenshots and more deliberate visual editing. For long pages or interfaces, vertical and horizontal scrolling capture can stitch a larger image. Configurable keyboard shortcuts add control for users who prefer a keyboard-led workflow.

Tensaku is a focused choice for Linux users who want capture, annotation, redaction, and basic image preparation in one application. Secure blur and black-out styles are useful when screenshots contain sensitive areas, and the crop tool includes aspect-ratio presets and dimension controls. The main boundary is its platform focus: it is designed for Linux Wayland environments, not a broad cross-platform setup. Its exports cover PNG, JPEG, and WebP, so it fits common image-sharing needs while remaining centered on screenshot work rather than a wider collaboration or review system. Choose Tensaku for layered Wayland screenshot editing; choose another tool if platform breadth is the priority.
