Renamer4Mac makes it really easy to rename a big number of files according to a preset pattern. It lets you rename your files in many different ways:

  • Search & replace
  • Insert/overwrite of text
  • Number the files
  • Convert upper/lowercase

All can be done with an easy user interface and real-time preview, so you can see how the files will be named just while you're configuring!
