Frequently Asked Questions

Why is this text case converter free?
As a professional IT solutions company, our business relies on our core enterprise services, not ad revenue. Because these tools process data entirely locally on your own device, they cost us virtually nothing to host. This allows us to provide high-quality, ad-free utilities to the community without needing to monetize your screen time.
Do you store or collect my text?
Absolutely not. There is a common saying in tech: "If you aren't paying for the product, you are the product." We built these tools specifically to challenge that standard. Because our tools use 100% client-side processing, your inputs never even reach our servers. We do not track your usage, use cookies, or harvest your data. Your privacy is mathematically protected by design.
What is sentence case?
Sentence case capitalizes only the first letter of each sentence and proper nouns. It is the standard format for most body text, emails, and general writing. Example: "The quick brown fox jumps over the lazy dog."
What is title case?
Title case capitalizes the first letter of major words in a title or heading. Minor words like articles (a, an, the) and short prepositions are typically lowercase. Example: "How to Write a Blog Post".
What is camelCase?
CamelCase writes compound words without spaces, with the first word lowercase and each subsequent word capitalized. It is commonly used for variable names in programming. Example: "userProfileData".
What is snake_case?
Snake_case writes compound words in lowercase with underscores separating each word. It is commonly used in Python, Ruby, and database column names. Example: "user_profile_data".
Can I convert long text safely?
Yes. The tool handles large amounts of text entirely in your browser. There are no server limits because no data is sent anywhere. However, extremely large texts (hundreds of thousands of characters) may take a moment to process.
