Two of the most popular screen annotation tools, side by side. Features, pricing, platforms — and what to pick if you’re on a Mac.
ZoomIt is a free screen annotation, zoom and break-timer utility from Microsoft Sysinternals. It originated on Windows and Microsoft has since released a macOS build. Its strength is zero-friction hotkeys and the integrated zoom feature — popular with sysadmins, presenters and trainers who want to show fine detail on screen.
Epic Pen is a Windows screen annotation tool designed around presentations and lessons. It lets you draw, highlight and (on the Pro tier) add shapes and text on top of any application. It has a friendlier UI than ZoomIt but is Windows-only — there is no native Mac build.

Epic Pen doesn’t run on macOS at all, and ZoomIt’s Mac port still feels like a Windows utility. If you’re on a Mac and want something that actually feels like a Mac app, Scribbble is built specifically for macOS — with a modern draggable toolbar, Apple Silicon native performance, and a richer toolset (Spotlight, Measure) than either ZoomIt or Epic Pen.
It depends on your platform and needs. ZoomIt is free, runs on both Windows and macOS, and includes a built-in screen zoom and break timer that Epic Pen doesn't have. Epic Pen has a more polished annotation UI and a Pro tier that adds shapes and text, but it's Windows-only. If you're on Mac, ZoomIt is the only one of the two that runs at all.
Three main reasons: (1) ZoomIt is fully free with no Pro tier, while Epic Pen gates shapes and text behind a paid upgrade. (2) ZoomIt includes a true screen zoom feature for showing fine detail, which Epic Pen lacks. (3) ZoomIt now runs on macOS — Epic Pen does not. Reviewers also note ZoomIt's zero-friction hotkeys feel faster than Epic Pen's toolbar.
Epic Pen has a friendlier, more modern annotation UI and is designed around presentation use. ZoomIt is a Sysinternals utility — minimal UI, hotkey-driven, with extra features (zoom, break timer, whiteboard mode) layered on. Epic Pen's free tier is limited to pen and highlighter; ZoomIt's full feature set is free.
Yes. Scribbble is a Mac-first screen annotation app that combines what's good about both — a modern, polished UI like Epic Pen, with the focused, hotkey-driven workflow of ZoomIt. It includes pen, highlighter, arrow, rectangle, text, Spotlight (focus dim) and Measure tools, free to download and try with a one-time license to unlock everything.
Most modern alternatives add at least one of: a Spotlight / focus-dim tool, a Measure tool for on-screen distances, a screen zoom (ZoomIt), or a built-in screen recorder (CleanShot X). Scribbble specifically adds Spotlight, Measure and a companion free Screenshot Annotate web tool. ZoomIt adds zoom, break timer and whiteboard mode.
On Windows, ZoomIt is the most-recommended free alternative. On Mac (where Epic Pen doesn't run at all), the most-recommended alternatives are Scribbble (modern Mac-first), Presentify (cursor highlighting), ZoomIt (free, Windows-style UI) and CleanShot X (capture + annotation).
Yes — ZoomIt is published by Microsoft as part of the Sysinternals suite, distributed directly from Microsoft's site. It's widely used in enterprise environments.
No. Epic Pen is Windows-only with no native Mac build. If you're on macOS, look at Scribbble (Mac-first), ZoomIt (free Microsoft port) or Presentify.
