Duplicate File Finder

Pick a folder — or select its files if your browser doesn't support folder access — and every file's contents get hashed with SHA-256. Files sharing a hash are true duplicates, no matter what they're named. Review the groups, see exactly how much space they're wasting, and clear them out. In Chrome, Edge, or Brave you can delete duplicates right from the page; in Safari or Firefox you get a clear, exportable list to act on yourself. One-time purchase, works offline forever.
