How it works
Three inputs. One calm workflow.

Safe by design
Know exactly what will happen.
Manifest puts review and control before every file operation.

Create renamed copies in a new folder while keeping the originals untouched.
No silent overwrites
Conflicts, duplicate names, invalid names, and unmatched files are clearly identified and skipped.
History and safe Undo
Review completed operations and reverse eligible changes with file identity protection.
Built for real work
Made for structured renaming workflows.
For photographers matching shoots to client lists, researchers applying sample IDs, agencies standardizing asset names, and teams organizing large file archives.

FAQ
Good to know.
What should the CSV contain?
A two-column CSV: the current filename in the first column and its new filename in the second.
Does Manifest overwrite existing files?
No. Conflicting and duplicate names are surfaced before processing and skipped instead of being silently overwritten.
Can I keep my original files?
Yes. Copy to a new folder is the default mode, so your source files remain untouched.
Can I undo a batch?
Manifest keeps an operation history. Eligible changes can be safely reversed, with per-file Undo available in Manifest Pro.
Are my files uploaded anywhere?
No. File processing happens locally on your Mac; your files and CSV are not uploaded.
Which macOS versions are supported?
Manifest is built for macOS 26 and later.
