Rename many files in the browser using a pattern with numbering while keeping the original files unchanged.
Files are not sent to a server. Processing runs in your browser, and the queue handles one file at a time so the device stays responsive.

How to use it
Add files, enter a name pattern such as file-{n}, choose the start number and step, then download renamed copies.
Recommended settings
Keep the extension when the renamed files should open in the same apps. Use {name} when you need to preserve part of each original filename.
Privacy
