All Case Converters

A case converter is a text transformation tool that changes the capitalization format of your text. Simply paste your text, select a conversion type (like uppercase, lowercase, camelCase, etc.), and instantly transform your text to the desired format. The tool preserves your original spacing and line breaks while only changing letter case.

ConvertCase.co offers 18 different case conversion formats including basic formats (Uppercase, Lowercase, Sentence Case, Title Case), programming conventions (camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE), creative formats (Alternating Case, Random Case), and specialized formats (Hashtag Case, Train-Case, COBOL-CASE, dot.case).

Absolutely. Our case converters preserve all line breaks, paragraph spacing, and text structure. Only the letter case is changed according to your selected format. Numbers, punctuation, and special characters remain unchanged.

Title Case follows professional style guides by capitalizing major words while keeping minor words (like 'a', 'the', 'and', 'of') lowercase. Capitalized Case capitalizes the first letter of every word without exceptions. Title Case is better for professional titles and headlines, while Capitalized Case is useful for names and certain display text.

Yes! There are no character limits. You can convert large documents, code files, or data exports of any size. The tool provides real-time statistics showing character count, word count, line count, and reading time as you work.

Yes, our converters support UTF-8 encoding and work perfectly with international characters, accented letters, and special symbols. Whether you're working with English, Spanish, French, German, or any other language using Latin script, the tool handles it correctly.

CONSTANT_CASE (also called SCREAMING_SNAKE_CASE) is the universal standard for naming constants and environment variables in programming. It uses all uppercase letters with underscores separating words (e.g., MAX_CONNECTION, API_KEY). This format makes constants highly visible and distinguishable from regular variables.

Use the Hashtag Case converter to automatically convert your text into hashtag format. It converts text to lowercase and adds a # symbol before each word, creating multiple hashtags separated by spaces (e.g., 'social media marketing' becomes '#social #media #marketing'). Perfect for Twitter, Instagram, LinkedIn, and TikTok posts.

kebab-case is the best format for URLs and web slugs because it's SEO-friendly, readable, and uses web-safe characters. Search engines treat hyphens as word separators, making 'best-practices-guide' better than 'best_practices_guide' or 'bestpracticesguide' for URLs.

Absolutely! If you accidentally typed with CAPS LOCK on, use the Toggle Case or Inverse Case converter to instantly fix your text. These converters swap uppercase to lowercase and vice versa. You can also use Sentence Case to properly format the text with correct capitalization.
