What Transnomino is
Transnomino is a free macOS utility for renaming groups of files. You can target a filename, path, extension, or full path, using actions such as find and replace, regular expressions, numbering, text insertion, case conversion, and diacritic removal. It can add file details—including creation dates, ID3 tags, and EXIF data—to names or paths. For images with EXIF GPS data, latitude and longitude can be used to retrieve address details such as street, city, and country. Conversion options include Windows-compatible filenames, custom lookup tables, and CSV uploads for lookup conversions. A real-time preview shows proposed changes, and you can combine actions into reusable recipes. Files can be sorted automatically or reordered by dragging and dropping. 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; legacy releases are listed for older macOS versions. AppleScript automation was temporarily removed in version 9.0.
