See before you save

Current and proposed values sit side by side, so a batch edit never becomes a leap of faith.

Artwork belongs with the music

Add, replace, remove or export embedded cover art for formats that support it.

Turn filenames into tags

Read common track, artist and title patterns from existing filenames instead of retyping the same information.

Turn tags into filenames

Build consistent names from track numbers, artists and titles. Tag checks the complete batch for collisions before anything moves.

Number the album in one click

Auto-number the selected tracks and set the total together — useful after a folder has been sorted into its final order.

The audio stays the audio

Tag updates the metadata container, preserves the sound data and keeps private fields it does not manage.

Every save is checked

The finished file is reopened and verified before it replaces the source. Undo Last Save can restore the latest batch.

Your collection stays private

Reading, editing, artwork and filename work happen entirely on your Mac. There is no upload, analytics or telemetry.
