Duplicate File Finder
Find identical files inside a ZIP, even when they have different names.
Private processing · No sign-up · Original upload removed after processing
How to use it
- Upload a ZIP containing the files to compare.
- Wait for the content comparison to finish.
- Review identical-file pairs and download the report.
A useful example
Check whether a delivery folder contains the same document under several filenames.
Good to know
Files are compared by SHA-256 and then by their contents. Nothing is deleted. Visually similar images or differently encoded documents are not treated as identical.
