About this app

Still renaming dozens or hundreds of files manually one by one?
Hyphenate is a fast, lightweight batch file renamer and string converter built to organize chaotic file and folder names in seconds.

Easily remove troublesome spaces from filenames, convert them into clean hyphens (-) or underscores (_), or execute bulk find-and-replace for custom text. Prevent web upload errors, terminal path issues, and messy storage with standardized, professional file names.

✨ Key Features of Hyphenate ✨
