Useful next steps

Rename a batch without changing the originals

Choose your files, put them in the order you want and enter a shared prefix. A prefix of project- creates names such as project-001.pdf and project-002.jpg. File extensions and contents are preserved.

Where are the renamed files?

Download the ZIP and extract it to get the renamed copies. The files on your device keep their original names. This tool does not rename files in place.

What can the prefix contain?

Use up to 100 characters without slashes or control characters. Check the previewed order before downloading. Processing happens in this browser.
