FastMarkup Free, v1.0.0

One tab. One frozen view. A clearer point.

Capture only the visible viewport and mark it without opening an editor tab. Your live page returns when you copy or press Escape.

The workflow

Chrome takes a snapshot before the overlay appears. You draw over that still image, then export the captured image with your marks.

Use the popup button or assign Alt+Shift+A to the capture command in Chrome shortcut settings.

Use the floating toolbar over the frozen viewport. The page underneath cannot receive pointer input until you close it.

Ctrl+C or Cmd+C copies a PNG. Download saves one to disk. The toolbar does not appear in the image.

Choose a color and stroke width, then draw directly on the snapshot.

Draw a freehand line or use a translucent highlight to point at a region.

Drag arrows, outlined rectangles, and ellipses over the captured page.

Place inline text or numbered markers for several points in one screenshot.

Use eraser, undo, redo, and clear all. Pick from six colors and three stroke widths.

FastMarkup Free has no account, upload, analytics, or screenshot history. Copy or download when you choose. Closing the overlay discards the capture.

Capture covers the visible tab viewport, not the whole scrolling page.
Chrome blocks extension injection on internal pages and other restricted URLs.
Final compatibility checks across sites, zoom settings, and high DPI displays are still pending.
Editable saved projects and structured review notes are in an unreleased Pro draft, not this free download.
