How the Case Converter works

This tool analyses your text in real time using clear, consistent rules for counting words, characters, sentences and paragraphs, and for transformations such as case conversion and cleaning. Where readability is measured, it uses established formulas such as Flesch reading ease. All processing happens in your browser as you type, so nothing you write is uploaded.

Tips & best practices

• Title Case capitalises major words; check your style guide, as some lowercase short words like "and" and "the".
• Sentence case is best for body text and gives a natural, readable result.
• Convert all-caps text to Sentence case to make it far easier to read.

Standards & accuracy

Provides accurate, real-time text analysis using consistent, transparent counting rules.

Counts follow consistent, transparent rules. Different platforms occasionally count characters slightly differently (for example, how they treat emoji), so check against your target platform for hard limits.
