Load an Unpacked Chrome Extension (from a ZIP)

Note: Chrome cannot load .zip files directly. First extract the ZIP so the folder contains your manifest.json and other files.

  1. Download the extension .zip file.
  2. Right‑click the ZIP and choose Extract (or unzip) to a folder.
    Make sure the extracted folder contains manifest.json at its root.
  3. Open chrome://extensions in Chrome.
  4. Turn on Developer mode (toggle in the top‑right).
  5. Click Load unpacked.
  6. Select the extracted folder (the one with manifest.json).
  7. Confirm the extension appears in the list and the toggle is enabled.
Troubleshooting
  • “Manifest file is missing or unreadable” — you likely selected the wrong folder. Choose the folder that directly contains manifest.json.
  • Permissions or errors shown — click Errors on the extension card to view details and fix issues.
  • On Microsoft Edge, use edge://extensions and follow the same steps.
