# Verifieddit Chrome Extension

> Right-click any image on any webpage. Verify it in place.

## What it does

The Verifieddit Chrome extension adds a context-menu entry — "Verify with Verifieddit" — to every image on every webpage. Click it and the extension:

1. Downloads the image bytes
2. Reads any embedded C2PA Content Credentials
3. Validates the cryptographic signature
4. Displays the verdict in a popup overlay

All cryptographic verification happens **inside the extension**, in the browser. The image is not uploaded to any server. The verification is the same engine that runs on [verifieddit.com](https://verifieddit.com/).

## Install

Download the latest signed extension package: [verifieddit-chrome-extension.zip](/verifieddit-chrome-extension.zip).

To install:

1. Unzip the file
2. Open `chrome://extensions/`
3. Enable "Developer mode" (top right)
4. Click "Load unpacked"
5. Select the unzipped folder

A Chrome Web Store listing is in preparation.

## For organisations — enterprise deployment

The extension is designed to be deployable via **Chrome enterprise policy**. Org admins can push the extension to every browser in the organisation through the standard Chrome management policy mechanism:

- ExtensionInstallForcelist push of the extension
- ExtensionSettings policy to lock down permissions
- (Enterprise tier) Usage reporting via [trusteddit.com](https://trusteddit.com/?utm_source=verifieddit&utm_medium=extension-md&utm_campaign=enterprise-deployment) for compliance teams to see content-provenance verification activity across the organisation in real time

Org-wide deployment is the qualified-lead pattern that maps to EU AI Act readiness. If your organisation is producing or distributing content into EU markets in 2026, every staff browser should be running this extension.

## What it verifies

Same as verifieddit.com: any image format with C2PA support (JPEG, PNG, WebP, HEIC, AVIF, TIFF). Videos and audio are not yet supported in the extension's context-menu flow but the main site handles them.

## Privacy

The extension requests only `contextMenus` and `activeTab` permissions. It does not access browsing history, does not run on every page by default, and does not phone home. See [/privacy](/privacy).
