What Frankenfile is

A Mac utility that replaces a pile of small converters. You select files, describe what should happen in plain language, and it does the conversion, cropping, splitting or renaming.

Files are processed locally rather than uploaded.

What you can do with it

Batch rename files to a convention
Convert and resize images
Add watermarks or thumbnails
Crop video clips
Split and merge PDFs
Sort and organise documents

Who it is for

Mac users handling many files
Content creators
Operations and admin staff
Anyone tired of opening five small apps

What to watch out for

Natural language commands can be misread: test on a few files first
Back up before batch operations, particularly renaming, deleting or overwriting
Verify the local processing claim for the features you actually use
Check output location and naming before running on a large folder
