Snap & Annotate - Screenshot Markup Tool Autor: Aditya Vijayavargia

Snap & Annotate turns a screenshot into a clear, shareable explanation — right in your browser, with no account and nothing uploaded to any server.

CAPTURE
• Visible area — grab exactly what's on screen.
• Full page — scroll and stitch the entire page into one tall image.
• Select area — drag a region on the page and capture just that part.
• Queue up to 10 screenshots and edit them together in one session.

ANNOTATE (in a full editor tab)
• Rectangle, square, ellipse, arrow, line and freehand pen
• Numbered step badges for walkthroughs
• Callouts and text labels with adjustable font size
• Highlighter
• Spotlight — dim everything except the area you want to focus on
• Blur — hide emails, tokens or anything sensitive
• Crop the screenshot down to just the part that matters

FINISH
• Move, resize (drag handles), nudge, undo/redo, per-shape colour and size
• Keyboard shortcuts for every tool, with an in-editor cheat sheet (press ?)
• Copy to the clipboard or download as PNG
• Combine several shots into one stitched image with a custom gap, or download them together
