The problem
Nobody ever renames ten files.
You rename four hundred, at the end of the day, and one wrong name breaks an edit or a render. The tool should show the result before it touches anything.
How it works
See the new name before it exists.
Select files or folders, stack the rules you need, and every new name shows up live as you type. Collisions are flagged before they happen, and the whole batch can be undone in one click.
Ten rules, one fixed order
Insert, replace, regex, case, date, numbering and more.
CLEAN
Strips accents and special characters: names every system accepts.
Live preview
Every name, every rule, updated as you type.
One‑click undo
The whole last batch, not file by file.
