An unofficial Chrome extension that finds and removes duplicate photos from your Google Photos library

What it solves

Google Photos lacks a built-in tool for finding and removing duplicate images. This project provides a Chrome extension that automates the process of identifying visually identical photos in a user's library and moving them to the trash.

How it works

The extension uses the Google Photos Toolkit (GPTK) to access the user's library via the web interface, bypassing the need for OAuth or a Google Cloud project. To identify duplicates, it runs MediaPipe's MobileNet V3 image embedder locally in the browser to generate image embeddings and find visually identical photos.

Who it’s for

Users who want to clean up their Google Photos library by removing duplicate images while keeping their data private, as all processing is done locally in the browser.

Highlights

  • Local Processing: No data leaves the browser, ensuring privacy.

  • OAuth-free: Accesses the library via an undocumented web API wrapper, removing the setup complexity of API keys.

  • Browser-based: Built as a Chrome extension using React and MUI.

  • Visual Matching: Uses image embeddings rather than simple file metadata to find duplicates.
