The smartest way to batch rename files on macOS.
Prefix, suffix, numbering, date, regex, case change — all with live preview.
Renamify gives you a clean two-panel interface — configure your rename rule on the left, then see every filename update in real time on the right before committing a single change. Drop files or folders, choose a rule, tweak the preview, and apply. That is the entire workflow.
