Paste text to clean, case-convert or transform it — every operation runs locally in your browser and nothing is ever uploaded.
What you can do with the Text Toolkit
The Text Toolkit bundles more than 200 everyday text operations into a single page, so you don't need a different site for each small job. Everything runs locally in your browser — your text is never uploaded — which makes it safe for drafts, private notes, code, and client work.
Case and formatting
Convert text to UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case, kebab-case and more. Clean up messy formatting by trimming leading and trailing spaces, collapsing repeated spaces, removing blank lines, and normalizing line endings between Windows (CRLF) and Unix (LF).
Lines and lists
Sort lines alphabetically or numerically, reverse their order, shuffle them, remove duplicate lines, add line numbers, and add or strip prefixes and suffixes. These are the operations you reach for when cleaning up a list of emails, keywords, or log entries.
Counting and analysis
See live counts of words, characters (with and without spaces), sentences, paragraphs, and estimated reading and speaking time as you type. Keyword-density analysis shows how often each word appears, which is useful for checking whether writing reads naturally rather than being stuffed with repeated terms.
Encoding and transformation
Encode and decode text for the web and code — URL encoding, HTML entity escaping, and Base64 — plus find-and-replace with optional regular-expression support for more advanced substitutions. Everything updates instantly, so you can chain operations one after another.
Text is more than visible letters
Digital text includes spaces, line endings, punctuation and invisible control characters. Operations such as trimming, line normalization and case conversion can therefore change data that is easy to overlook.
Unicode made text global but more complex
Modern text can represent writing systems and symbols far beyond ASCII. A visible 'character' is not always equivalent to one byte---or even one simple code unit in every programming environment.
Frequently asked questions
Is my text uploaded to a server?
No. Every operation runs locally in your browser, so your text is never uploaded. You can safely process drafts, private notes, code, or client work.
How many text operations are included?
Over 200, covering case conversion, whitespace cleanup, line sorting and deduplication, counting and analysis, and encoding such as URL, HTML entity and Base64.
Can I use regular expressions for find and replace?
Yes. Find-and-replace supports optional regular-expression mode for advanced substitutions, alongside plain-text matching for simpler edits.
Does it work offline?
Once the page has loaded, the tools keep working without a connection, because all processing happens on your device rather than on a server.
