Rename files on your device?

This changes the original files in the selected folder. Files with problems will be skipped. You can undo this during the current session only.

Saved presets

Reset all rules?

This removes every rule you've configured. This can't be undone, though your saved presets are unaffected.

How it works

Choose files or a folder, build one or more renaming rules, and watch the preview table update instantly. When you're happy with the results, rename the original files directly (if your browser supports it) or download the renamed copies.

Privacy

Your files are processed locally in your browser and are not uploaded to our servers. Presets are saved only in your browser's local storage. No analytics collect filenames, paths, or rules.

Supported browsers

Direct folder renaming uses the File System Access API, available in current Chromium-based browsers (Chrome, Edge, Opera, Brave). Other browsers, including Firefox and Safari, automatically use the rename-and-download mode instead.

Limitations

Folders themselves aren't renamed in this first release, only the files inside them. Undo is available for the current browser session only and can fail if files change outside the app. Very large ZIP downloads depend on your device's available memory.

Frequently asked questions

Are my files uploaded anywhere?

No. Renaming and previewing happen entirely in your browser using local file APIs. Nothing about your files is sent to a server.

What happens if two files end up with the same new name?

The preview marks them as duplicates and the rename button stays disabled until you resolve it — either by adding automatic numbering, skipping the conflicting files, or adjusting your rules.

Can I undo a rename?

Yes, for direct folder renaming, an "Undo last rename" button appears after the operation completes and works for the rest of your browser session. It can't undo changes made outside the app.

Does this work on my phone?

The rename-and-download mode works on mobile browsers. Direct folder renaming needs the File System Access API, which is currently limited to desktop Chromium browsers.
