About Text & Unicode Toolkit

What this site is

Text & Unicode Toolkit is a static website with eight tools for everyday text tasks. There are no accounts, no uploads and no server-side processing: each tool is a small JavaScript function that runs on your own device as you type or change an option.

Who it is for

The tools are built for people who handle text all day: writers and editors checking length and formatting, SEO specialists and marketers preparing slugs and metadata, developers and data analysts cleaning lists and debugging Unicode, and students or office workers tidying text copied from documents, emails and PDFs.

Principles

A few principles guide how the tools are built.

• Fast: pages are lightweight and results appear instantly.
• Private: text is processed in the browser and never sent to a server.
• Solid Unicode handling: emoji, combining accents, NFC and NFD forms, and Vietnamese text are handled deliberately and covered by tests.
• Honest results: each tool page explains what the tool does and where its limits are.

The eight tools

The toolkit currently includes:

• Word & Character Counter: words, characters, sentences, paragraphs, lines and reading time.
• Case Converter: lowercase, UPPERCASE, Sentence case and Title Case.
• Remove Accents: strips diacritics from Latin letters, with an option for đ/Đ.
• Slug Generator: turns titles into clean URL slugs.
• Whitespace Cleaner: collapses spaces, trims lines and tidies blank lines.
• Remove Duplicate Lines: keeps the first occurrence and the original order.
• Sort Lines: alphabetical, numeric, by length or reversed.
• Unicode Normalizer & Inspector: NFC, NFD, NFKC, NFKD, code points and byte lengths.
