What Renaming Actions Does Transnomino Support?

Updated

Transnomino supports a broad set of batch renaming actions on macOS: find and replace (with wildcards), regular expressions, insert text, prefix/suffix, set filename, numbering, trim, case changes, diacritic removal, Windows compatibility conversion, and file selection subsets. Each action can target the filename, path, extension, or full path, and actions can be chained and previewed in real time. It requires macOS 14 or later (version 10.1.0); older systems need a legacy version.

Core text actions

These cover most everyday cleanup and standardization tasks.

Action What it does Typical use
Find and Replace Replaces text, with wildcard (*) support Fix a recurring typo or token across many files
Regular Expressions Advanced find-and-replace using patterns Strip variable date stamps, reorder name segments
Insert Text Adds custom text at a specific position Insert a project code at a fixed offset
Prefix and Suffix Adds text to the start or end of filenames Tag a batch with a client or version label
Set Filename Assigns specific names to files Rename a short list to exact target names
Numbering Adds sequential numbers Order scans or exports (e.g., report_01, report_02)
Trim Removes characters from the start or end Cut stray underscores or leading zeros

Case, characters, and compatibility

  • Case changes: convert to ALL UPPERCASE, all lowercase, Capitalize Each Word, capitalize the first word, or Titlecase (capitalizing major words).
  • Diacritic removal: simplifies accented characters, so "é" becomes "e" — useful when filenames must stay plain ASCII.
  • Windows compatibility: converts filenames so they are valid on Windows, handy before sharing files with Windows users.

Targeting and sequencing

Every action can be applied to the filename, path, extension, or full path. That path-level targeting is what enables organizing files into folders — for example, sorting photos into directories by date and GPS location. You can sequence multiple actions and preview results in real time as you build the sequence, so you can verify the outcome before committing.

Metadata-driven renaming

File attributes such as creation date, ID3 tags, and EXIF data can be added to filenames or paths. Dates can use preset formats or a custom format you define. For images with EXIF GPS data, latitude and longitude can be used to retrieve address details (street, city, country).

Narrowing the batch

File Selection lets you create subsets of files and apply specific actions only to those subsets — useful when one folder mixes file types that need different treatment.

Automation

Transnomino also supports automation; the vendor documents this on a dedicated Automation page. If you rename on a recurring schedule, check that page for the supported approach before building a manual workflow.

Is it a fit?

If your task is covered by the actions above — text cleanup, numbering, case normalization, metadata-based sorting, or Windows-safe names — Transnomino's feature set addresses it. The main constraints to check first are the macOS 14+ requirement and whether your specific metadata (e.g., a particular tag format) appears in the supported File Attributes list in the changelog. The software is described by its publisher as free, with optional donations.
