What this Text Analyzer does

This all-in-one text analyzer gives you instant insights into any text — character count, word count, sentence detection, line statistics, paragraph breakdown, and UTF-8 byte size. It also checks your text against real character limits for Google, X, LinkedIn, Instagram, and SMS. Everything runs entirely in your browser with zero data uploaded to any server.

  1. 1.Paste your text into the input area, or drag and drop a .txt / .md / .json / .csv file directly onto the editor.
  2. 2.View real-time statistics — characters, words, sentences, lines, paragraphs, and UTF-8 byte size update instantly as you type.
  3. 3.Check the Platform Limits panel to see how your text length compares to Google, X, LinkedIn, Instagram, and SMS character limits.
  4. 4.Copy stats to clipboard, download as TXT, or clear the editor to start a new analysis.

Frequently asked questions

Is my text uploaded to any server?

No. Every calculation — character count, word count, byte size, and all other statistics — happens entirely in your browser. Your text never leaves your device, making this tool completely private.

Does it work with Chinese, Japanese, Korean, and other non-English languages?

Yes. The word counter uses the browser's Intl.Segmenter API, which provides accurate word boundary detection for English, Chinese, Japanese, Korean, Thai, and many other languages. Mixed multilingual text is handled correctly too.

Can I analyze very large text files?

Yes. The tool uses an optimized processing pipeline that keeps the interface smooth even with multi-megabyte texts. Large inputs are automatically handled without lag or browser freezing.

How is the UTF-8 byte count calculated?

The tool uses the browser's built-in TextEncoder API to encode your text as UTF-8 and measures the resulting byte length. This gives you the exact file size the text would occupy when saved as a UTF-8 encoded file on disk.

What platform character limits are shown?

The Platform Limits panel shows real character limits for: Google Title (60 characters), Meta Description (160), X / Twitter (280), LinkedIn Post (3,000), Instagram Caption (2,200), and SMS (160). Your current text length is compared against each limit.

Does this tool work offline?

Yes. Once the page is loaded, all analysis runs locally in your browser. You can disconnect from the internet and the tool will continue to work — your text is never sent anywhere.

How accurate are the statistics?

The tool uses browser-native APIs (Intl.Segmenter for words, TextEncoder for bytes) and well-tested algorithms for sentences, lines, and paragraphs. Results are equivalent to desktop text editors and professional word processors.
