Can files with different names still be duplicates?

Yes — comparison is based purely on file content (SHA-256 fingerprint), completely ignoring filenames.

Are my files uploaded to any server?

No — all hashing and comparison occurs locally in your browser memory.

Identify duplicate files across multiple uploads by comparing their exact cryptographic hashes.
