Batch File Renamer review
A local browser tool for building, validating, and exporting multi-step rename workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Batch File Renamer is an open-source, client-side web application for renaming multiple files in a browser. It is aimed at people who need repeatable rename workflows without directly changing their original files. Users can import individual files or folders, arrange rename operations by drag and drop, review proposed names, and export selected renamed copies as a ZIP archive. The feature set covers regular-expression replacement, numbering, date and time insertion, case conversion, extension changes, presets, and operation history.
Its standout capability is the ordered rename pipeline. Multiple operations can be combined and reordered, allowing a workflow to apply transformations in a defined sequence rather than relying on one broad rename action. Live preview and validation status provide a checkpoint before export, while built-in and custom presets support recurring naming patterns. Undo and redo apply to changes made to the operation pipeline, which helps refine a workflow before producing the output archive.
The local browser model keeps original files unchanged and makes the output model clear: Batch File Renamer creates renamed copies and packages selected results as a ZIP. That suits users who want a reviewable, reversible preparation step or need to share a completed archive. It is less suitable for workflows that require direct renaming on the filesystem, completed-rename undo, or a desktop-native process. Choose it for browser-based, pipeline-oriented batch renaming; choose another tool when direct file operations are central to the workflow.
Batch File Renamer pros and cons
- Where it wins
- Ordered pipelines combine regex, numbering, dates, and case changes.
- Live previews show proposed names and validation status before export.
- ZIP export preserves originals while delivering renamed copies.
- Where it doesn't
- It exports renamed copies instead of modifying files directly.
- Undo and redo cover operation changes, not completed renames.
- Browser-based workflows may not suit direct filesystem renaming needs.
