Transnomino free download for Mac


26 February 2020

Free batch-rename utility.


Transnomino offers a set of renaming actions, ranging from simple text replacements to more complex replacements using regular expressions (regex). Any number of these actions can be placed in sequence and you can directly preview the results while you create them. Renaming sequences can be saved as a recipe to be re-used later.

Numbering can be added to the beginning or end of the filename. It's possible to exactly specify the number of digits to allow for better sorting of the files by filename. The files in the list can be dragged and dropped to change the order.

All renaming actions can be applied to the Name, Path or Extension of the files

Transnomino supports insertions of File Attributes from the files like: EXIF, ID3, FLAC. And if EXIF GPS Longitude and Latitude data is available it is even able to use this information to lookup Address information.

  • Simple find / replace (with wildcard support)
  • Find / replace with Regular expressions
  • Case changes, such as upper/lower-case and capitalize
    • all uppercase
    • all lowercase
    • capitalize each word
    • capitalize first word of the filename
  • Numbering
  • Prefix/Suffix and Setting of filenames
  • Removal of diacritics

Great app. Saved me lots of time with regex, plus the regex helper tool is great. Regex can be a bummer to learn, and this makes it easy peasy.

I have been using Transnomino for a long time and find it better than paid for apps. The developer has always been responsive and very polite. If you are looking for a file renamer, I really like how you can create "recipes" that you can save and use different "recipes" depending on what kind of renaming you need to do. Very well done and so many options, but not cluttered. Very easy to use.

Went to their site to get this, and while it does seem to work, there are no instructions. I need to use the wildcard feature, after 20 minutes of trying to figure it out I gave up. I don't have time to play around. You could have the greatest tool in the world, but if you don't tell anybody how to use it, it becomes useless.

The download link that MacUpdate has appears to be broken. The app can be downloaded directly from the dev here:
