Are my files sent to any server?

No! Absolutely zero files are uploaded. Simple Rename runs entirely inside your browser's client-side memory via JavaScript and Web APIs.

How does direct folder renaming work?

On supported browsers (Google Chrome, Microsoft Edge, Opera, Brave), the 'Open Folder' button uses the File System Access API to grant permission to modify files directly inside the selected folder on your disk.

What file types are supported?

All file types are supported! JPEG, PNG, WEBP, PDF, DOCX, MP4, MP3, ZIP, code files, and anything else. EXIF metadata extraction is supported on JPEG and TIFF images.
