Batch Rename
Rename multiple files in your browser with prefix, suffix, replace, and numbering rules
Free Batch File Renamer — Rename Multiple Files at Once
Rename multiple files at once using patterns, automatic numbering, find-and-replace, and case conversion — entirely in your browser. Files are processed locally, so nothing is uploaded and your data stays completely private.
Batch renaming is essential for organizing photo collections, preparing files with consistent naming conventions for a project, cleaning up downloaded files with messy auto-generated names, or preparing assets for platforms with specific filename requirements. Renaming files one at a time manually is slow and inconsistent.
Add your files, choose a renaming pattern, preview the new names before applying, and download the renamed files as a ZIP.

Frequently Asked Questions
Can I add sequential numbers like photo_001, photo_002?
Yes. Sequential numbering with a customizable starting number and zero-padding is a core feature of the batch rename tool.
Can I preview the new file names before renaming?
Yes. The tool shows you a preview of every new file name before you apply and download, so you can catch any mistakes first.
Does renaming change the file content?
No. Only the file name changes. The content, format, and data inside each file remain completely unchanged.
