How to use File Name Cleaner

Add the requested files.
Review the options and the displayed queue.
Select Clean File Names, inspect the result, and download the generated ZIP.

What this file tool does

The cleaner removes control and cross-platform-reserved characters, tidies whitespace, preserves extensions, resolves collisions, and packages renamed copies.

Separate base name and extension, apply chosen cleanup rules, resolve duplicates, then write unchanged bytes to a ZIP.

Downloading renamed copies does not rename the originals on disk. Review the preview before replacing any files.

Supported inputs and limits

The tool works with files exposed through the browser picker. Actual limits depend on available device memory and browser support.
