Independent Chrome Extension MVP

PAGE CAPTURE

An honest, minimal full-page screenshot tool. Stitches visible tab increments into a single lossless PNG directly on your machine.

Product baseline 9c6e61a / functional standard trials (current instrumentation d4d5ba3)

Current implementation

Full-Page PNG Export

Exports stitched PNGs; standard fixture dimensions and marker fidelity were measured, other layout coverage remains pending.

activeTab Permission Model

Requires no broad host permissions or background web snooping. Operates only on user invocation via keyboard shortcut or extension icon.

No Account or Remote Storage

Designed for local processing without accounts or remote storage. Full-context runtime network observation is pending; no comprehensive privacy certification is claimed.

Requires Native Chrome

Engineered as a clean Manifest V3 extension taking full advantage of Chrome's native visible tab capture and dedicated viewer origin.

Physical Fixture Verification

Verified against standardized automated test fixtures across 3 standard trials with 15 markers measured independently (receipts: standard-three-null-grades, but no quality grade; scoped fixture dims).

Standard Tall Fixture Baseline

  • Test Viewport Dimensions: 900 × 657 CSS px (DPR 2)
  • Fixture Document Canvas: 900 × 3200 CSS px
  • Natural Output Image: 1800 × 6400 px PNG
  • Scroll Restoration: Standard fixture: initial 137 returned 137; broader cases pending
  • Header Repeat Policy: Sampled seams in standard fixture showed no repeated fixed header; broader layout coverage pending.
  • Verification Baseline: Product baseline 9c6e61a / functional standard trials (current instrumentation d4d5ba3)
  • Standard Trials: 3 standard trials, 15 markers measured independently; current receipt standard-three-null-grades but no quality grade; scoped fixture dims

Shortcut default: Alt+Shift+P (macOS: Option+Shift+P).

Provenance & Integrity

Original GoFullPage implementation code and assets were not reused; this analog was independently authored from recorded black-box observations.
