Character Count
Measure text locally with live character totals, no-space counts, word and line counts, UTF-8 bytes, and a 280-character remaining counter.
What does Character Count do?
Character Count reports characters, words, lines, and UTF-8 bytes for pasted text.
- Primary use: Character Count reports characters, words, lines, and UTF-8 bytes for pasted text.
- Key technical fact: UTF-8 uses 1 to 4 bytes per Unicode code point, so byte count can exceed visible character count.
- Practical check: Review Unicode, whitespace, line break, and punctuation behavior before treating the output as production text.

Measure characters, lines, and UTF-8 bytes
Character Count helps you check text against hard length limits for posts, SMS-style messages, database fields, API payloads, titles, descriptions, and validation rules. It reports total characters, characters without spaces, words, lines, UTF-8 bytes, and remaining characters against a 280-character reference limit.
Character counts and byte counts are not the same. ASCII usually uses 1 UTF-8 byte per character, while accented letters, CJK characters, emoji, and many symbols can use multiple bytes. Some platforms also count grapheme clusters, links, or emoji sequences with their own rules.
How to use
- Paste or type your text into the input editor.
- View live statistics in the panel below the editor. All metrics update instantly as you type.
- Check the Twitter remaining counter to see how many characters you have left for a tweet. It turns red when you exceed 280 characters.
- Use Copy to copy the text to your clipboard, Download to save it as a text file, or Clear to reset everything.
What is Character Count?
Character Count is a local measurement tool for checking visible length and encoded size before you paste text into a form, API request, database column, or social post.
The UTF-8 byte total is useful when systems limit storage by bytes instead of characters. Newlines, spaces, tabs, combining marks, and emoji can affect counts, so test with the exact text you will send.
Input notes
Use this counter for a close local estimate, then confirm in the target platform when limits are strict. X/Twitter, SMS gateways, search snippets, databases, and APIs may apply their own counting or normalization rules.
Example
Emoji can make the UTF-8 byte total larger than the visible character count:
--- Sample Text --- Hello, World! 🌍 --- Expected Statistics --- Total Characters: 16 Characters (no spaces): 14 Words: 2 Lines: 2 Bytes (UTF-8): 18 Twitter remaining: 264
MCP integration
MCP (Model Context Protocol) lets AI agents and apps discover and run Coding.Tools utilities for repeatable conversions, formatting, hashing, and generation workflows.
MCP tool name: character-count
MCP endpoint: https://coding.tools/mcp
Call tools/list first. Each tool entry includes inputSchema, outputSchema, and examples so an AI agent or client can build valid arguments without guessing.
For tools/call, read result.content[0].text for the display value and result.structuredContent for machine parsing. Tool-level failures return isError: true; protocol failures return a JSON-RPC error.
Example tools/call request:
curl -s https://coding.tools/mcp \
-H "Content-Type: application/json" \
-H "Accept: application/json" \
-H "MCP-Protocol-Version: 2025-06-18" \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"character-count","arguments":{"input":"MCP endpoint is ready for tool automation."}}}'
Most text and data tools accept an input string plus optional options. Browser-only image tools are listed for discovery and return a web UI link when they need browser image APIs.
