RenameKit

What RenameKit is

RenameKit is a visual batch renamer for people organizing creator projects, development files, or media libraries. It shows current and proposed filenames side by side before changes are applied, and detects filename conflicts in advance. Users can combine more than 40 rules for text, numbering, regular expressions, metadata, and extensions without writing scripts. The app can rename any file type; metadata rules work with JPEG and TIFF EXIF, MP3 and FLAC tags, and MP4 and MOV video metadata. RenameKit runs locally, and says files stay on the user's computer. A complete batch can be rolled back, even after restarting the app. Downloads are available for Windows x64, macOS Apple Silicon and Intel, Linux AppImage, and Debian/Ubuntu. The Lifetime License costs $9.99, paid once and includes presets and a CLI tool. Its three-day full-feature trial allows evaluation before purchase; after the trial, batches are limited to 20 items. A license is activated once in the app and can be deactivated and moved to another computer, though only one device can use it at a time. Customers can request a refund within 14 days of purchase.

Who it suits

RenameKit suits photographers, developers, media teams, and anyone cleaning up large or disorganized folders. It is useful for people who want to build repeatable rename rules, inspect changes before applying them, and work with metadata without writing scripts.

Limits

The full-feature trial lasts three days. After the trial, batches are limited to 20 items without the Lifetime License; that license is for one device at a time.

Getting started

1. Download the installer for Windows, macOS, or Linux.
2. Open RenameKit and arrange files for a batch rename.
3. Stack rules and review the proposed filenames and conflict warnings.
4. Use the three-day full-feature trial, or purchase and activate the Lifetime License in the app.
5. Deactivate the license before moving it to another computer, if needed.

Verdict

Pick RenameKit if you need visual, rule-based batch renaming across Windows, macOS, or Linux, especially for media metadata or large folder cleanups. Consider the paid license if you need batches above 20 items after the three-day trial; it costs $9.99, paid once.
