PixelSnap

A macOS‑only utility that lets users measure distances and dimensions directly on the screen. By dragging a rectangle or using crosshair mode, the tool instantly detects object boundaries, displays the distance between points, and can hold dimensions on‑screen or copy them to the clipboard. It also supports measuring multiple objects simultaneously and adding snappable horizontal and vertical guides for alignment checks.

The application integrates with popular screenshot tools, allowing users to capture the measured area as an image and export it for collaboration. Features such as keyboard shortcuts, Touch Bar support, Retina‑ready rendering, and customizable appearance make it adaptable to different workflows. A tolerance mode and the ability to hide the menubar icon provide additional control over the measuring experience.

Designed for professionals and anyone who needs precise on‑screen measurements, the software runs across all applications on macOS, offering a lightweight, fast, and stable solution for tasks ranging from UI design to general productivity.
