Purpose: Bulk Renamer is a native desktop app for batch-renaming files in a selected folder.
Preview: It shows a live preview of each file’s new name before changes are applied.
Rename options: Rename patterns can combine find and replace, prefixes or suffixes, sequential numbering, case conversion, and extension changes.
Regex: Find and replace supports plain text or regular expressions.
Folder scope: The app loads files in the selected folder but does not include subfolders.
Validation: Before renaming, it checks for duplicate destination names and names that already exist on disk; a conflict prevents the batch from proceeding.
Undo limit: Undo reverses only the most recent successful batch and is stored in memory, so it does not persist after the app closes.
License: The app is open-source under the MIT license.
Platforms: Downloads are listed for macOS Apple Silicon and Intel, Windows 64-bit, and Linux .deb or AppImage.
Launch warning: The maker says unsigned apps may show standard Gatekeeper or SmartScreen warnings on first launch until code-signing is set up.
Intended users: The maker describes Infinite Creation’s free tools as being for people who create, validate, publish, and teach media.
