File preparation

Filename Cleaner

Turn a batch of messy names into a consistent list. Review each suggestion and catch duplicates before you rename your files.

Original filenames

One filename per line. Paste names without folder paths.

Naming style

The final extension keeps its original spelling and case. Duplicate checks ignore case.

Review proposed names

Edit a suggestion to make it distinct. Changing the naming style regenerates the suggestions.

Everything runs in this browser tab. Only the names you paste are checked. Your files stay untouched.
