Frequently Asked Questions
1. What is a Bulk File Renamer?
A Bulk File Renamer (or Batch File Renamer) is a tool that allows you to change the names of multiple files at the same time using set rules, such as adding prefixes, suffixes, or numbering, instead of renaming each file individually.
2. Are my files uploaded to a server?
No. All renaming and ZIP packaging happen entirely locally in your web browser. Your files are completely private and are never uploaded to our servers.
3. Can I undo a rename operation?
Because the tool generates a new ZIP file containing the renamed files, your original files on your device are not modified. If you make a mistake, simply adjust the rules and download a new ZIP, or discard the ZIP entirely.
