Renamer review
A focused renaming specialist for cross-platform file collections and repeatable workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Renamer is a desktop batch file renaming application for macOS and Windows. It is designed for individuals and small teams managing photos, music libraries, documents, and other file collections. Its central job is applying repeatable naming changes across large groups of files, with support for live previews, regular expressions, metadata, and CSV-based input. The cross-platform availability makes it suitable for users who work across both major desktop operating systems.
The standout capability is its workflow model. Reusable workflows called Renamerlets can combine chained renaming actions, allowing recurring processes to be saved and applied again. The feature set covers EXIF and GPS metadata insertion, ID3 and Apple Lossless metadata support, and CSV-based renaming. Optional local AI Assist can generate rename workflows, while smart undo and file backup provide ways to review or recover from changes. Together, these features make Renamer more suited to structured collections than to occasional one-off filename edits.
Renamer is a focused tool rather than a general file manager. Its positioning centers on renaming workflows, so users seeking verified file browsing, archive handling, multi-pane navigation, or broader integrations should choose a product built around those functions instead. For buyers who need repeatable batch renaming on macOS or Windows, the combination of reusable workflows, chained actions, metadata handling, regex support, and CSV input is the main reason to consider it. Renamer uses a license and provides a Buy Now option, and optional local AI Assist adds another workflow-generation path without changing its narrow focus.
