Bulk Rename Files – No Upload Required

How It Works

Select files from your computer, define renaming rules (find & replace, add prefix/suffix, change case, add sequence numbers), preview changes, and download renamed files as a ZIP. Everything happens in your browser.

Common Use Cases

• Organize photos by adding dates or descriptions
• Add sequence numbers to downloaded files
• Standardize file naming conventions in projects
• Clean up messy download names
• Rename documents for better searchability

Privacy & Security

All file processing happens entirely in your browser. Your files are never uploaded to any server, never stored, and never transmitted over the internet. We cannot see or access your files.

This tool uses modern browser APIs to read and process files locally. Downloaded files are packaged as a ZIP archive and saved directly to your computer.
