Frequently Asked Questions

What renaming patterns are supported?+

Base name plus sequential numbering (vacation-001, vacation-002…), find-and-replace within existing names, and case changes — the operations that cover most cleanup jobs.

Are the original files modified?+

No — your files on disk are untouched. Renamed copies are packaged for download, so mistakes cost nothing.

What's the typical use case?+

Camera imports (IMG_4032.jpg → wedding-042.jpg), messy download folders, and preparing consistent file sets for clients or uploads.

Is there a file limit?+

Hundreds of files process quickly — renaming is a light operation done entirely in your browser.
