Screenshot Master

About

Screenshot Master is a powerful, privacy-first screenshot tool built directly into Chrome — no servers, no tracking, just fast local captures.
🖼️ Three Capture Modes

Visible Area — one-click viewport snapshot
Full Page — auto-scrolls and pixel-perfectly stitches the entire page
Selected Region — drag a custom bounding box over any part of the page

🎨 Built-in Annotation Engine
Draw rectangles, arrows, text labels, highlights, and freehand pen strokes directly on your screenshot. Adjust color and stroke width per tool. Undo any step with Ctrl+Z.
💾 Flexible Export
Download as PNG or JPEG, or copy directly to clipboard for instant pasting. Screenshots are auto-named with domain and timestamp.
⌨️ Keyboard Shortcuts

Alt+Shift+V — Visible Area
Alt+Shift+F — Full Page
Alt+Shift+S — Selected Region

All shortcuts are fully customizable via chrome://extensions/shortcuts.
🔒 100% Private
All processing is local and in-browser. No data is collected or transmitted. Storage is cleared immediately after the preview tab loads.
Perfect for developers, designers, QA testers, students, and content creators.
