What is OpenCapture (Browser Extension)?

OpenCapture is a lightweight, local-first browser extension for full-page screenshots, scrollable container captures, and image annotations—without subscriptions, artificial paywalls, or telemetry.

Designed as a transparent, open-source alternative to tools like GoFullPage, Awesome Screenshot, and Nimbus, OpenCapture processes everything client-side inside the browser sandbox:

  • Full-Page & Container Stitching: Automatically scrolls and stitches full web pages as well as nested, scrollable <div> containers.
  • High-DPI / 2x Rendering: Native Retina support to keep text and vector assets sharp on high-resolution displays.
  • Smart Page Splitting: Slices ultra-long captures into separate, manageable segments to prevent browser canvas memory crashes.
  • Built-in Redaction & Markup: Annotate with arrows, shapes, and freehand tools, or sanitize credentials using pixelate/blur filters before saving.
  • Multi-Format Export: Export locally to PNG, JPEG, or multi-page PDF documents without watermarks.
  • Zero Telemetry & Local-First: No accounts, no cloud dependencies, and zero background analytics. Your captured data never leaves your machine.
