A screen overlay for presenting on Windows. Zoomify freezes and zooms the screen, lets you draw on top of it, spotlights or magnifies one region, and runs a countdown timer, each from a global hotkey. What you draw can be copied or saved as PNG, SVG or PDF.

Ctrl+1 |
Static zoom: freeze the screen, wheel to zoom, drag to pan, draw on top |
Ctrl+2 |

Ctrl+3 |
Spotlight: dim everything but a circle, wheel to resize |
Ctrl+4 |

Ctrl+5 |
Countdown timer, with overtime and a corner pill |
Ctrl+6 |
Loupe: a floating lens, wheel to zoom, Space to pin |
Drawing
- Pen with Bezier smoothing and pen pressure, and a highlighter.
- Lines and arrows, which bow into curves and stay attached to the shapes they point at.
- Rectangles, rounded rectangles, ellipses, text, sticky notes, numbered step badges and a blur box for redacting.
- A laser pointer with a fading trail, and an eyedropper that picks colours off the screen.
- Select, move, resize, group, align and snap; undo and redo.
- Whiteboard and blackboard slates, an infinite canvas you can pan past the screen edge.
Saving and sharing
- Copy to the clipboard, save a PNG snapshot, or export SVG or PDF, at 1×, 2× or 3×.
- Paste images in from the clipboard.
- Several boards per session. Sessions autosave and can be reopened.
