OpenScreenShot

About

OpenScreenShot is a free, open-source screenshot extension — zero data leaves your device, no account needed, no telemetry, no third-party services.

### Privacy

OpenScreenShot is privacy-first unlike the other tools:
 - All capture, annotation, and export happens entirely locally in your browser
 - No data is ever uploaded, collected, or transmitted
 - No analytics, no ads, no third-party services
 - The extension uses only the permissions it needs: activeTab (current page), scripting (scroll measurement), storage +
   unlimitedStorage (settings + image handoff), downloads (save files)
 - Never requests broad <all_urls> host permissions

### Capture modes

 - 📄 Full Page — Scrolls and stitches the entire page into one seamless image. Fixed headers appear once at the top. Live progress
   bar shows capture status.
 - 👁 Visible Area — Captures exactly what's on screen now. Instant.
 - ✂️ Selected Region — Click and drag to select any area on the page. Supports resize handles, keyboard nudging (arrow keys, Shift =
   ×10), cancel (Esc) and confirm (Enter).

### Annotation editor

After every capture, the full-screen editor opens in a new tab. Annotate your screenshot before exporting:

 - Drawing tools: Rectangle, Arrow, Freehand pen, Text (click-to-type overlay), Blur (pixelate an area), Crop (drag a region and
   apply)
 - Style controls: Pick from 8 colors, adjust stroke width (3/6/12), and font size (12–96px) — your settings are remembered across
   sessions
 - Editing: Select, move, and resize annotations with corner/edge handles; undo/redo (⌘Z/⌘⇧Z); delete (⌫)
 - Navigation: Scroll-wheel zoom toward cursor, space-drag or middle-click to pan, fit/100% zoom buttons

### Export

Export your annotated screenshot from the editor:
