UndoRedoIcons

UndoRedoIcons are graphical symbols used in software interfaces to represent the functions of undoing and redoing actions. These icons enable users to revert changes or reapply them, providing a fundamental part of interactive editing, coding, and data manipulation applications. The most common representation for undo is a leftward curved arrow, while redo is usually depicted as a rightward curved arrow, often mirrored from the undo icon. The visual similarity underscores the reversible nature of the operations and facilitates quick recognition across platforms such as Microsoft Office, Adobe Creative Cloud, GIMP, and web-based text editors.

The origin of this iconography dates back to early graphical user interface (GUI) design in the 1980s, where icon sets performed a role similar to textual commands. Many systems adopt a rounded arrow resembling a circle segment to emphasize the idea of looping back to a previous state. Designers often use consistent line weights and color schemes to ensure the icons are distinct yet harmonious with the surrounding toolbars. Accessibility best practices recommend pairing icons with textual labels or tooltips, as icons alone may be ambiguous or misunderstood by users with visual impairments.

In user‑interface guidelines from major operating systems—such as Apple's Human Interface Guidelines, Microsoft's Fluent Design System, and Google's Material Design—undo and redo icons are standardized. The recommended practice is to place them near each other, retain high contrast for visibility, and make duplicated actions quickly reversible. While the visual language of undo and redo icons remains largely uniform, variations exist to fit specific design contexts: some applications use an animated ripple or sequence, others incorporate double arrow or rewind‑type imagery. The consistent application of these icons supports user expectation and reduces cognitive load, ensuring a smooth editing experience across diverse software ecosystems.
