Programming Projects

Different languages have different naming conventions. Converting between styles helps you follow each language's best practices and maintain clean, readable code.

  • • JavaScript variables: camelCase
  • • Python functions: snake_case
  • • CSS properties: kebab-case

Content Writing

Proper capitalization makes your writing look polished and professional. Different contexts call for different styles - headlines need impact, body text needs readability.

  • • Article headlines: Title Case
  • • Body paragraphs: Sentence case
  • • Important notices: UPPERCASE
  • • Section headings: Capitalize Words

Social Media Posts

Case styles can completely change how your post feels. All caps grabs attention but can feel aggressive, while alternating case adds playfulness. Choose based on your message tone.

  • • Important announcements: UPPERCASE
  • • Relaxed conversations: lowercase
  • • Playful content: AlTeRnAtInG
  • • Ironic comments: iNVERSE cASE

Frequently Asked Questions

Title Case vs Capitalize Words - what's different?

Title Case follows English grammar rules - it skips small words like "and," "the," "of" unless they start the title. Capitalize Words just makes every single word start with a capital letter, no exceptions.

camelCase or PascalCase - which should I pick?

camelCase starts lowercase and works great for variables and function names (like "getUserData"). PascalCase starts uppercase and fits better for class names and types (like "UserAccount"). It's mostly about following conventions.

What about numbers and special characters?

Numbers stay exactly the same in all conversions. Most special characters do too, except when converting to programming formats like snake_case or kebab-case - those might remove or replace some symbols to create valid variable names.

Can I upload really large files?

Since everything happens in your browser, it depends on your device's memory. Files up to a few megabytes usually work great, but huge files might make things sluggish. Try breaking them into smaller chunks if needed.
