Rename easily
Renaming many files at once has never been easier. With Renamer you can find and replace text in filenames, number files, insert or remove characters from filenames, as well as convert between lower, upper and mixed case.
Rename quickly
For those of you that want that extra edge on speed, Renamer offers the ability to save common rename tasks to presets, and to rename files directly from Finder.
Rename like a pro
Renamer puts the ultimate renaming power at your fingertips. With chains you can group a sequence of rename actions and apply them at once on the same set of files. And with regular expression you can complete even the most complex rename tasks in seconds.
