MATTRN Screenshot

About

MATTRN Screenshot is a fast, local-first screenshot tool for Chrome. Capture an entire webpage or the visible window, review the result in a focused preview workspace, make lightweight annotations, and export the file in the format that fits your workflow.

Designed for creators, researchers, QA teams, support teams, and anyone who needs clean browser captures without sending page content to an external service.

Key features:

- Full-page webpage capture with automatic scrolling and stitching
- Visible-window capture for quick saves
- Preview workspace with zoom, fit-to-page, and clean review controls
- Lightweight markup tools for drawing, highlighting, text notes, and redaction-style callouts
- Local capture history for revisiting recent screenshots
- Export as PNG, JPG, or PDF
- Auto-download mode for quick full-page captures
- Customizable keyboard shortcuts
- Local-first processing with no account required

MATTRN Screenshot works best on normal `http` and `https` webpages. Chrome does not allow extensions to capture restricted pages such as the Chrome Web Store, `chrome://` pages, browser settings, or some protected internal pages.
