Transnomino
What it is
Transnomino is a free batch-renaming utility for Mac that applies changes to many files at once. Its actions include finding and replacing text, regular expressions, adding text or numbering, trimming, changing case, and removing diacritics. You can direct actions at a filename, path, extension, or full path, and use creation dates, ID3 tags, or EXIF data in names and paths. For images with EXIF GPS data, latitude and longitude can retrieve address information such as street, city, and country. Conversion options include Windows-compatible filenames, custom lookup tables, and CSV-based lookup conversions. A real-time preview shows proposed results; actions can be ordered into sequences and saved as reusable recipes. Files can be sorted automatically or rearranged by dragging. The app can also be launched from the command line with directories and recipe files or recipe JSON. Version 10.1.0 requires macOS 14 or later, and legacy releases are listed for older macOS versions. AppleScript automation was temporarily removed in version 9.0.
