Fixing capitalization shouldn’t take longer than writing the sentence. SnipText’s free Case Converter switches text to UPPERCASE, lowercase, Sentence case, Title Case, or aLtErNaTiNg-instantly, accurately, and without storing your text.

What you can convert

  • UPPERCASE: Useful for headings, labels, and emphasis.
  • lowercase: Standardize style, especially for usernames or tags.
  • Sentence case: Capitalizes the first letter after a period/exclamation/question mark.
  • Title Case: Capitalizes key words while respecting small words (of, and, the) and hyphenated terms.
  • Alternating case: Playful casing for memes and attention-grabbing snippets.

How to use it (fast)

  1. Open the SnipText Case Converter.
  2. Paste your text or start typing.
  3. Click the case you want (Upper, Lower, Sentence, Title, Alternating).
  4. Copy, download, or apply the result back to the input.
  • Preserve ACRONYMS: Keep all-caps terms such as NASA or HTML unchanged.
  • Capitalize after colon: In Title Case, words following a colon can be capitalized for style consistency.
  • Hyphen-aware titles: Handles parts of hyphenated words individually (State-of-the-Art).

Why a case converter matters

Consistent casing improves readability and brand voice. It’s helpful for headings, emails, UI labels, social posts, academic titles, and data cleanup (CSV/Excel). Automating it reduces typos and saves time-especially in bulk edits.
