Batch Rename Files

About Batch Rename Files Tool

This tool renames multiple files at once using customizable patterns. Upload your files, set prefix, suffix, and numbering format, preview the new names, and download renamed files. Perfect for organizing photos, documents, or any file collection. All processing happens in your browser for complete privacy.

How does batch renaming work?

Upload multiple files, configure the rename pattern (prefix, suffix, numbering), preview the new filenames, and click Rename Files. Each file will be downloaded with its new name.

What renaming options are available?

You can add a prefix (text before), suffix (text after), and sequential numbering (001, 01, or 1 format). You can also choose to keep or remove file extensions. All options can be combined.

How does numbering work?

Choose a numbering format: 001 (three digits), 01 (two digits), or 1 (no padding). Set the start number (default 1). Files will be numbered sequentially in the order they were selected.

Can I preview names before renaming?

Yes! The tool shows a live preview table with original names and new names side-by-side. Any changes to settings update the preview instantly.

What happens to file extensions?

By default, file extensions are preserved. If you uncheck 'Keep File Extension', the extension will be removed from renamed files.

Can I rename photos in sequence?

Absolutely! This is perfect for renaming photo collections. For example: prefix 'Vacation_', numbering '001', will create Vacation_001.jpg, Vacation_002.jpg, etc.

Is my data safe?

Yes! All file renaming happens in your browser. Your files are never uploaded to any server. The renamed files are downloaded directly to your device.

What file types can I rename?

You can rename any file type - images, documents, videos, archives, code files, and more. The tool works at the file level, so the content type doesn't matter.
