Free Utility: FullPage Snap is distributed free of charge by Tanager Software. Built with zero cloud telemetry and 100% on-device canvas rendering.

Capture the Entire Page. Mark It Up. Bind into PDFs.

Standard screenshot utilities are limited to the visible viewport, leaving you to manually scroll and piece together multiple snippets. Many web-based alternatives send your private pages to remote cloud servers.

FullPage Snap is a lightweight, modern Manifest V3 browser extension built with local-first privacy. It automatically scrolls, captures viewport tiles, suppresses distracting sticky headers, and stitches high-resolution full-page images in background offscreen canvas documents.

Key Capabilities

1. Seamless Full-Page Stitching

  • Automatically scrolls long web documents, articles, dashboards, and code repositories.
  • Stitches viewport slices into a single continuous, full-resolution PNG image.
  • Powered by Chrome’s modern Offscreen Documents API (chrome.offscreen) for background canvas rendering.

2. Sticky & Fixed Header Suppression

  • Prevents annoying sticky navigation bars, floating notification headers, and fixed footers from duplicating repeatedly across the page.
  • Automatically hides floating elements during capture and restores them when done.

3. Persistent Capture Library

  • Captures are automatically saved to your browser’s local offline storage (unlimitedStorage).
  • Review, search, tag, or export previous captures anytime from the extension popup.

4. Multi-Page PDF Binder

  • Select any set of saved screenshots from your local library.
  • Compile them into a single, multi-page PDF document with one click.
  • Ideal for archiving multi-page documentation, client reports, or transaction receipts.

5. In-Browser Annotation Studio

  • Open any capture in the built-in interactive viewer equipped with:
    • Crop Tool: Interactively trim captures to specific bounding areas.
    • Shapes & Lines: Rectangles, ellipses, and straight lines with customizable colors and stroke weights.
    • Text Annotations: Add clear callout labels and text notes directly on the image.
    • Highlighter: Semi-transparent color markup over text and diagrams.
    • Freehand Pen: Draw diagrams and freehand sketch arrows.
    • Undo/Redo: Full history stack to easily revert changes.

6. Flexible Export Options

  • Download PNG: Save high-res raster images.
  • Export PDF: Print or save as multi-page or single-page PDF.
  • Copy to Clipboard: Copy directly to your system clipboard for instant pasting into Slack, GitHub, or emails.
  • 100% Private: Runs entirely inside your browser sandbox with zero external network requests.
