Namesmith

What it does

• Chain as many steps as you need

  Pick from 27 actions in 11 categories, including regular expressions with capture groups and names from a list or CSV. Reorder, disable or duplicate any step.

• A preview that flags problems

  Removed and added characters are highlighted in every row. Each file is marked as rename, unchanged, numbered, clash or invalid before you start.

• Names from capture date, camera and tags

  Namesmith reads EXIF, TIFF and GPS from JPEG, HEIC and RAW photos, and ID3, iTunes and QuickTime tags from audio and video. Type {captured:yyyy-MM-dd} or {track:2} and add |slug or |pad:N.

• RAW and JPEG stay together

  RAW+JPEG pairs and .xmp or .aae sidecars get renamed as one. Swaps and case-only renames work, clashes are caught, and no file is ever overwritten.

• Undo that survives a restart

  Your undo history persists across launches. Old and new names export to CSV, so you keep a record of every batch.

• Rename from Finder or the command line

  Save a chain as a preset and run it from the Finder Services menu, from a small app you drop files on, or from the command line with --preset, --dry-run, --recursive and --undo.
