Convert Case transforms your text in seconds. Whether you're writing a professional document, crafting a message, or fixing a copy-paste from the web, Convert Case handles the formatting so you don't have to.
Features:
- Seven conversion modes: UPPERCASE, lowercase, Sentence case, Capitalized Case, Title Case, aLtErNaTiNg cAsE, and InVeRsE CaSe.
- Programming Cases: convert text to camelCase, PascalCase, snake_case, kebab-case, SCREAMING_SNAKE_CASE, or dot.case — built for code identifiers, with a tokenizer that handles spaces, camel humps, uppercase runs (HTMLParser → html_parser), and Unicode letters.
- Fancy Fonts: type your text and instantly preview it in 20 Unicode font styles — Script, Fraktur, Double-Struck, Circled, Squared, Small Caps, and more. Copy or share any style with one tap, and favourite the ones you use most.
- Remove Formatting tool: strip extra spaces, line breaks, HTML tags, URLs, emojis, em & en dashes, punctuation, numbers, and more — multi-select the cleanup options you need and apply them all at once.
- Encoder / Decoder: encode and decode text as Base64, URL percent-encoding, ROT13, UTF-8 hex bytes, HTML entities, binary, and Unicode escapes — pick an encoding, toggle Encode or Decode, and see the result update as you type.
- Sync text between tools: paste once and the same text shows up in Home, Fancy Fonts, Remove Formatting, Encoder, and Programming Cases — switch between tools without re-pasting.
- Available in 14 languages: English (US/UK), German, Spanish, French, Portuguese, Polish, Italian, Hungarian, Slovenian, Greek, Filipino, Hindi, Turkish, and Ukrainian — with an in-app language picker so you're never stuck with the system default.
- Smart locale handling: respects German ß → ẞ, Turkish dotted-I rules, and language-specific small-word lists for proper Title Case in French, German, Spanish, and Italian.
- Settings your way: pick your language, choose System / Light / Dark theme, toggle the background notification, auto-copy converted text to your clipboard, sync text between tools, remember text between sessions, and fine-tune the 3000+ built-in proper-noun corrections with your own custom terms.
- Background reminder: switch to another app with text waiting and Convert Case will quietly remind you to come back and finish the job — turn it off any time.
- Clipboard integration: one-tap paste brings text from any app straight into Convert Case, and one-tap copy sends the result back out.
- One-tap sharing: Send converted text directly to messages, email, or social media without switching apps.
- Quick-launch shortcuts: long-press the app icon to jump straight into Fancy Fonts, Remove Formatting, Encode / Decode, or Programming Cases without first landing on the home screen.
- Works offline: Full functionality without an internet connection, every time.
- Simple interface: No learning curve. Open the app, paste your text, pick your format, done.
- Download Convert Case and stop wasting time on manual reformatting.
