File Rename Tool – Simple Browser File Renamer (No install, no upload, no signup & Free to Use)

I built RenameTool because I kept running into the same frustrating problem: renaming files should be easy, but every solution out there felt either too complicated, too slow, or unsafe.

Most tools require installs, command-line skills, or uploading your files to someone else’s server — and that just didn’t feel right for something as basic as renaming a folder full of files.

So I made RenameTool — a privacy-first, browser-based file renamer that runs entirely on your own device.
No signup. No account. No ads. No uploads. Just:

✅ Select a folder
✅ Set rename rules
✅ Preview changes
✅ Rename files in seconds

Especially useful for:

• Designers with messy asset folders

• Students with tons of project files

• Developers organizing builds/logs

• Anyone who hates renaming files manually

It even handles batch renaming quickly — and everything stays local in your browser.
