Get it from the Snap Store

tempren is a powerful file renaming utility that uses flexible template expressions to generate names for your files.
Tag templates can modify original filename, extract metadata from the files or anything in between.
A rich library of built-in tags helps with working with many common file types out-of-the-box.

Whether you need to organize your files, standardize naming conventions, or perform complex renaming tasks, tempren can help you get the job done efficiently.


  • Template-based filename/path generation
  • Built-in Audio/Video/Images metadata extraction tags
  • Ad-hoc tags to leverage external programs for metadata extraction
  • Configurable, metadata-based file selection (filtering) and sorting

Installation and documentation

For comprehensive documentation, including installation instructions, all features, advanced usage, and troubleshooting, please visit the Manual page.


Note: When experimenting on your own please use --dry-run flag!
tempren will not override your files by default but invalid template can mangle their names.
