Nomina
Rename everything.
Break nothing.
A modern bulk file renamer built from scratch. Stack rules, preview everything, undo anything. No clutter, no legacy baggage - just a clean tool that does one thing well.
Philosophy
File renaming tools shouldn't look like they're from 2004.
Most bulk renamers are powerful but painful - cramped layouts, arcane syntax, and interfaces that fight you every step. Nomina is the tool you'd build if you started fresh today with no baggage.
Preview everything
See exactly what will change before you commit. Every rule shows its effect in real-time with conflict detection built in.
Undo anything
Full persistent undo history across sessions. Made a mistake three days ago? Roll it back like nothing happened.
Your files, your machine
No cloud, no accounts, no telemetry. Runs as a single portable executable from wherever you put it.
Accessible to everyone
WCAG 2.2 AAA compliant. Full keyboard navigation, screen reader support, colorblind filters, and font scaling up to 150%.
Stack rules. See results. Done.
18 chainable rename rules.
Find and replace, regex, case conversion (13 modes), sequential numbering, date insertion from EXIF, content hashing, extension manipulation, and more. Stack them into a pipeline and watch the preview update live.
See before you commit.
Every rule change updates the preview instantly. Original and renamed columns side by side with status indicators and conflict warnings.
Full undo. Always.
Every rename operation is backed up automatically. Persistent history across sessions means you can undo changes from days or weeks ago. Automatic backups before every operation.
Save and share presets.
Save your rule pipelines as .nomina files. Share workflows with your team or reuse them across projects.
Edit names by hand.
When rules aren't enough, open the inline text editor and rename files individually. Load current names, tweak, apply.
Right-click to rename.
Add Nomina to your Windows Explorer context menu. Right-click any folder and open it directly in the app.
Filter before you rename.
Narrow down files by name pattern, file type, or size range. Only rename what you actually want to change.
Make it yours.
Light, dark, or system theme. Pick from 18 accent colors, adjust zoom from 70% to 150%, toggle compact mode and zebra striping.
Built for everyone.
WCAG 2.2 AAA compliant from day one. High contrast mode, screen reader optimization, keyboard navigation, colorblind filters for deuteranopia, protanopia, and tritanopia, plus font scaling from 80% to 150%.
See it in action.
Three steps. That's it.
Pick a folder
Browse the folder tree or right-click in Explorer. Select the files you want to rename.
Stack your rules
Add rules to the pipeline - find and replace, case conversion, numbering, dates, whatever you need. Preview updates live.
Rename
Hit the button. Files get renamed. Don't like it? Undo. The history sticks around even after you close the app.
Modern foundations.
A modular Rust core handles all rename logic, wrapped in Tauri v2 for native Windows integration. The interface is React 19 with TypeScript. One portable executable, no installer, no registry changes.
Name things properly.
A file renamer that's fast, accessible, and gets out of the way. No learning curve, no subscription, no catch.
