Bulk rename files

Rename many files at once with patterns, numbers, dates and find and replace. Free, private, nothing uploaded.

How it works, privately

How it works, privately

  1. Choose your files. You can also drop files on the page. They open in this browser tab; nothing is sent anywhere.
  2. Build the new names and check the preview first.
  3. Save the result to your device. Close the tab and nothing is left on any server, because nothing was ever sent.

Are my files uploaded?

Does it work on my phone?

Do I need to install anything?
No. Open the page and use it. You can also add Toolbox to your home screen like an app.
