Convert Case: Text Converter

Convert Case changes the case of your text and cleans up its formatting. Paste text from a document, a message or a web page, pick a case, and copy the result back out. It gives the same results as convertcase.net.

Features:

- Seven cases: UPPER CASE, lower case, Sentence case, Capitalized Case, Title Case, aLtErNaTiNg cAsE and InVeRsE CaSe. Sentence case keeps abbreviations, initials such as U.S. and quoted sentences right, and Title Case keeps short words such as "and" and "of" in lower case.

- Programming Cases: camelCase, PascalCase, snake_case, SCREAMING_SNAKE_CASE, kebab-case and dot.case, with a tab for each. Your text stays as you typed it and the converted text appears below, so you can switch between cases freely. Each line is converted on its own, and words in any alphabet are kept whole.

- Fancy Fonts: 66 Unicode styles, including Script, Fraktur, Double-Struck, Circled, Small Caps, Upside Down, Mirror, Strikethrough and Underline. Tap a style to copy it, filter the list by name or by words such as "cursive" or "bubble", and pin the styles you use most to Favorites at the top.

- Remove Formatting: remove extra spaces, leading and trailing spaces, line breaks, empty lines, HTML tags, URLs, emojis, em and en dashes, punctuation, numbers and special characters. Choose as many options as you need and apply them at once. Ordinary text is left intact: "don't" keeps its apostrophe, "$3.50" keeps its decimal point, and accents and other alphabets are kept. Your choices are remembered.

- Encode / Decode: Base64, URL encoding, ROT13, UTF-8 hex bytes, HTML entities, binary and Unicode escapes, updated as you type. If you paste encoded text while Encode is chosen, the app offers to decode it.

- Undo: Clear, Remove Formatting and a conversion can be undone for a few seconds afterward.

- Sync text between tools: paste once and the same text is in Convert, Fancy Fonts, Remove Formatting, Encode / Decode and Programming Cases.

- 14 languages: English (US and UK), German, Spanish, French, Portuguese, Polish, Italian, Hungarian, Slovenian, Greek, Filipino, Hindi, Turkish and Ukrainian.

- Language rules: German ẞ in capitals, Turkish dotted İ, Greek capitals without accents, and Title Case keeps the short words of French, German, Spanish and Italian in lower case.

- Proper nouns: over 3,000 names and abbreviations (iPhone, NASA, YouTube) keep their casing. Words that are also ordinary words, such as "rest" or "polish", only keep it where you typed them that way. Add your own terms in Settings.

- Settings: language, System, Light or Dark theme, copy after converting, sync text between tools, and remember text between sessions.

- Reminder notification: if you leave the app with text in it, a notification lets you come back and convert it. You can turn it off in Settings.

- Paste, copy and share: one tap to paste text from another app, copy the result, or share it to messages, email or social media.

- Quick-launch shortcuts: long-press the app icon to open Fancy Fonts, Remove Formatting, Encode / Decode or Programming Cases directly.

- Works offline: everything works without an internet connection, and your text stays on your device.

- Text selection menu: select text in another app and tap Convert Case. Gmail, Google Messages and Google Keep don't show other apps in this menu.
