Batch Rename Files Online

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.

No files selected.

The pattern supports {n} and {name}. Files are not changed; copies with new names are created.

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

Your files are not uploaded to a server. The editor runs in your browser with local libraries from this site.

Limits

Large images can take longer on phones. If the browser slows down, process fewer files at once or choose a smaller output format.
