Drive Duplicate Cleaner

Find and trash duplicate files in Google Drive folders by MD5 checksum. Runs entirely in your browser, with no server and no data leaving your machine except calls to Google.

1. Connect

Advanced: use a different OAuth Client ID

In Google Cloud Console, enable the Google Drive API.
Under APIs & Services → Credentials, create an OAuth client ID of type Web application.
Add this page's origin as an Authorized JavaScript origin:
On the consent screen, choose Internal (Workspace) or add users as test users. Paste the client ID below.

A default client ID is built in. The token stays in memory and is never stored.

2. Configure

Root folder IDs or URLs (one per line, or "root" for My Drive)

Like the Apps Script, each root's immediate subfolders are scanned. Duplicates are only detected within a single subfolder.

Duplication window (hours) File age filter (days, 0 = all)

Excluded folder IDs or URLs (one per line) Excluded extensions (comma separated, e.g. png, jpg)

Scanning never changes anything. You review the results first, then choose what to trash.
