Text Toolbox

Q: Does this tool send my text anywhere?

No. Every transformation — case conversion, sorting, find & replace, counting — runs entirely in your browser using JavaScript. Nothing is uploaded to a server.

Q: How is the word count calculated?

Words are counted as sequences of letters, numbers, apostrophes, and hyphens, similar to how most word processors count words. Punctuation and whitespace are treated as separators.

Q: Why is UTF-8 byte length different from the character count?

JavaScript's character count reflects Unicode code points. When encoded as UTF-8 (the encoding used by most APIs, files, and databases), characters outside the basic ASCII range — accented letters, emoji, CJK characters — take 2 to 4 bytes each, so the byte length can be larger than the character count.

Q: What happens if my find & replace pattern is an invalid regular expression?

The tool validates the pattern before running it and shows an explicit error message instead of silently failing or crashing, so you always know whether the replacement actually happened.
