What It Does

Features

📄

Full-Page Scroll Capture

Automatically scrolls the page and stitches all captured frames into a single seamless high-resolution PNG. Works up to 30,000px tall.

✏️

Rich Annotation Suite

Arrows, lines, rectangles, circles, text labels, numbered steps, and freehand drawing. All with color, weight, and opacity controls.

🙈

Privacy Blur & Redact

Brush or box-select any area to apply Gaussian blur. Pixel-out redaction removes data entirely. Great for sharing screenshots publicly.

✂️

Smart Region Crop

Click-and-drag to select any region of the captured screenshot for precise cropping. Keyboard shortcuts for exact pixel values.

📤

Multi-Target Export

Save as PNG or PDF, copy to clipboard, or share via a temporary link. PDF output includes page metadata and timestamp.

🎬

Screen Recording

Record the current tab or entire screen with optional microphone audio. Exports as WebM with no time limit.

📐

Element Capture

Right-click any element on the page and capture just that element — no viewport constraints, perfect for components and sections.

📁

Screenshot Library

All screenshots are saved to an in-extension library organized by site and date. Search, tag, and manage your capture history.

Frequently Asked Questions

It works on 99%+ of sites. Pages with complex CSS transforms (3D effects) may capture with slight rendering differences. Chrome's internal pages (chrome://) cannot be captured by design.

Up to 30,000px height. For pages taller than this, SnapFull auto-splits into multiple images named sequentially.

No. All screenshots are stored locally in your browser's extension storage. The shareable link feature uses a temporary local URL that expires when the tab is closed.

Yes. Screenshots in the Library can be reopened in the annotation editor at any time.
