What Is TextToolbox?
TextToolbox is a free collection of 100+ online text utilities built for writers, developers, marketers, and social media creators. Whether you need to generate bold Unicode text for your Instagram bio, remove duplicate lines from a CSV export, convert a sentence to title case, or decode a binary string, choose a tool that matches the operation you need. No installation, no sign-up, no cost.
Which Tool Should I Use?
Start from the job you need done. Each tool page lists its own input limits, examples and limitations.
| Job | Tools | Good to know |
|---|---|---|
| Style a short name, bio or caption with Unicode letters | The result is substituted characters, not real formatting. Paste a short sample into the destination field first. | |
| Clean a pasted list | Remove repeated lines, blank lines or stray spaces without retyping. | |
| Count words, characters or sentences | Useful for limits on forms, captions and essays. | |
| Change capitalization | Compare several case styles for the same text before copying one. | |
| Compare two versions of a text | See what changed between a draft and a revision. | |
| Convert text to another representation | Morse, binary or Braille mappings for learning, puzzles and checks. | |
| Generate a username, password or random string | Check each tool’s page for what it randomizes and its limits. | |
| Find a symbol or kaomoji to copy | Search curated collections and copy the exact character. |
Limits Worth Knowing
- Styled Unicode text is made of substituted characters. Apps, fonts and screen readers handle it differently, so keep important information in plain text.
- Every tool has an input limit. For example, Change Case accepts up to 200,000 UTF-16 units and Font Generator up to 2,000 source grapheme clusters; the tool page states the exact figure.
- Copy relies on your browser’s clipboard permission. If it fails, select the output and copy it manually.
Browser-Based Tools and Website Data
Browser-based processing does not make a website visit private under every condition. TextToolbox pages include analytics and third-party scripts, and features such as theme, recent tools and favourites can use browser storage. Check the tool’s save, copy, export or share actions and the Privacy Policy. Keep confidential material out of a workflow until its handling meets your requirements.
