Umbe

Built for Real Workflows

Photographers coming home from a shoot. Online sellers naming product photos. Parents finally organising years of family pictures. Document wranglers taming a folder of client invoices. These are the people Umbe is made for — people who need to rename a hundred files consistently, repeatedly, and without opening Terminal.

Stack Rules, Build Pipelines

Every rename is a pipeline. Add as many rules as you need, in any order, and Umbe applies them in sequence to every file.

• Replace Text — find and replace any string in the filename
• Add Prefix / Add Suffix — prepend or append any text
• Number Sequence — auto-number files with configurable start, step, padding, and separator
• Change Case — lowercase, UPPERCASE, Title Case, or camelCase
• Remove Text — strip a pattern from every filename at once
• Date (Fixed) — stamp files with a specific date in any format
• Date from Metadata — pull the EXIF date-taken from photos and use it in the name

Live Preview — Always On

The preview column updates the instant you change anything. You see the exact output name for every file before anything is touched. Conflicts — two files that would end up with the same name — are flagged inline in red so you can fix them first.

Presets for Repeating Jobs

Save any rule stack as a named preset and reapply it in one click next time. Presets are stored locally on your Mac, not in the cloud.

Undo Anything

Made a mistake? One click undoes the entire batch rename and restores every original filename, right in the same session.

Native and Private

Umbe is a native Mac app built in SwiftUI. No subscription, no account, no internet connection required. Your files stay on your Mac.
