    description
    Tired of retyping text just to change the case? Select text anywhere in your browser, right-click, and convert it instantly - no copy-pasting to external tools.
    
    Convert Case is a fast, lightweight text case changer with 16 conversions, keyboard shortcuts, automatic clipboard copy, and full UI translations in 15 languages. Change case directly in your browser - select, right-click, done. Works on regular web pages, Google Docs, Reddit, and more.
    
    Writing conversions:
    UPPER CASE, lower case, Title Case, Sentence case, Capitalized Case, No Accents
    
    Developer conversions:
    camelCase, PascalCase, snake_case, CONSTANT_CASE, param-case (slugify), dot.case, path/case
    
    Utility conversions:
    Alternating Case, Inverse Case, No Case (plain lowercase words)
    
    Features:
    - Change case in place via right-click context menu
    - Keyboard shortcuts for quick access (Alt+U, Alt+L, Alt+C, Alt+A) - or set your own
    - Copy After Conversion - automatically copies converted text to the clipboard
    - Automatic proper noun casing in Title Case, Sentence case, and Capitalized Case - thousands of names, places, brands, and acronyms are recognised and cased correctly (Paris, IBM, Abu Dhabi, iOS) - toggle off or add your own custom terms in Settings
    - Counts submenu with live character, word, sentence, and line counts for the current selection
    - Configurable Title Case options (ignore words like "the", "and", "of")
    
    Works with:

Changelog:
- 2.4.2 - Title Case and Capitalized Case now capitalise the letter after a forward slash — `loving each other/hurting each other` becomes `Loving Each Other/Hurting Each Other`; accented letters after quotes, brackets, and slashes are also handled correctly
- 2.4.1 - Refined the built-in proper noun list to reduce false positives, including removals like WHO and JAR so common words are less likely to be forced into acronym casing
- 2.4.0 - Conversions in input and textarea fields now dispatch input/change events so host pages register the update — fixes silent reverts in tools like Yoast meta titles and React-controlled inputs
- 2.3.1 - Refined the built-in proper noun list to avoid false positives for common words (e.g. "us", "one", "man", "ice", "raw", "arm", "pet") that were being incorrectly capitalised
- 2.3.0 - New "Proper Nouns" setting replaces Ignored Words and Correct Words; toggle auto-correction of built-in proper nouns and abbreviations on or off, and add your own custom terms whose casing overrides the built-in list. Existing Correct Words are migrated automatically; Ignored Words are retired (add the word in your preferred casing to the new list instead)
- 2.2.0 - Translated into 15 languages (English, British English, German, Greek, Spanish, Filipino, French, Hindi, Hungarian, Italian, Polish, Portuguese, Slovenian, Turkish, Ukrainian); follows your browser's language automatically, with an override in Settings
