Bulk Renamer vs Easy File Renamer

Bulk Renamer is a free desktop app for batch-renaming files in a chosen folder, available for Linux, macOS, and Windows. It displays a live preview of each proposed filename before applying the batch. Rename patterns can combine find-and-replace, prefixes or suffixes, sequential numbering, case conversion, and extension changes; find-and-replace accepts plain text or regular expressions. The app loads files from the selected folder but does not include subfolders. Before a batch runs, it checks whether destination names duplicate one another or already exist on disk, and a conflict blocks the operation. Undo reverses the latest successful batch only. That history is kept in memory and does not remain after the app closes. Bulk Renamer is open-source under the MIT license and its free plan costs nothing, with no account required. The maker notes that an unsigned app may trigger standard Gatekeeper or SmartScreen warnings on first launch until code-signing is set up. Infinite Creation describes its free tools as serving people who create, validate, publish, and teach media.

Easy File Renamer batch-renames files and folders on macOS, Windows, and the web using configurable rules. It previews proposed names before applying changes to disk. System Renamer provides 12 named rules, including text replacement, prefixes, numbering, case conversion, and extension changes. Rule stacks can be saved and reloaded as macros for repeat jobs. Media Renamer builds photo and video names from date, camera, dimensions, filename, and sequence tokens. Music Fixer reads and updates common audio tags, edits album art, and loads an exported iTunes Library XML file. Cloud File Renamer is a free browser companion for supported cloud accounts, while the desktop application does not scan cloud accounts itself. The trial permits adding files and previewing names, but registration is required to perform a rename. The add-files list holds 1,500 items; larger jobs use folder indexing. The maker says desktop files stay on the user’s computer and installers are digitally signed. Plans start at $39.99 a year.
