DeCapper 4+

A tiny, fast-launching macOS application for changing text case of sentences to lowercase, uppercase, title case or standard capitalization.

Need to change the case on a headline for social media? Don’t retype it, drag it into DeCapper. With Auto-Copy enabled, DeCapper copies changes to the clipboard, ready for pasting into Facebook, Twitter, Instagram and more.

Have an uppercase video file name with underscores instead of spaces?

With “Replace underscores with spaces” enabled, DeCapper makes changing all uppercase file names quick and easy.

Change text to uppercase, lowercase, title case, or standard (capitalize the first word and change the rest to lowercase).

Need to re-capitalize some words? Make one word stand out with all uppercase? Fix a title in the middle of a sentence? Keyboard shortcuts / menu commands will do that for you.
