What is a File Rename Tool?
A File Rename Tool is an online utility that allows you to change the names of multiple files at once without installing any software. Whether you need to add prefixes, suffixes, sequential numbers, or perform find-and-replace operations on filenames, this tool handles it all directly in your browser.
How to Rename Multiple Files?
Renaming multiple files with Tools24 is simple:
- Select or drag and drop your files into the upload area.
- Choose a rename method: Quick Rename for single files, Batch Rename for rules applied to all files, or Advanced for case changes and space handling.
- Preview the changes before applying them.
- Click "Apply Rename" and download your renamed files individually or as a ZIP.
How Batch Rename Works
Batch rename applies one or more rules to every selected file simultaneously. You can combine rules like adding a prefix, inserting sequential numbers, and replacing specific text — all in a single operation. The tool processes filenames as strings, preserving the original file contents and format entirely.
Is it Safe to Rename Files Online?
Yes. The Tools24 File Rename Tool processes everything locally in your browser. Your files never leave your device during the rename process. No data is uploaded to any server.
Are My Files Uploaded?
No. Your files are processed locally in your browser whenever possible. Files are not uploaded to our server for normal renaming operations. The only network requests made are to load the tool itself and the JSZip library needed for ZIP creation.
